Answer:

The magnitude of the displacement of the ball = 35

Explanation:

The initial location of the ball = The 15-yard line

The height to which the ball is kicked = 24 feet

The location where the ball lands = The 40-yard line

The location the where the ball rolls to and stops = The 50-yard line

The displacement = The change in location of the ball

∴ The displacement = Final location - Initial location

The displacement = 50-yard line - 15-yard line = 35 yards

The displacement of the ball = 35.

Given :

Velocity of bullet, \(v_b=300\ m/s\).

Mass of bullet, m = 0.005 kg.

Mass of rifle, M = 5 kg.

To Find :

The recoil velocity of the rifle.

Solution :

Since, their is no external force is acting.

So, momentum of the system will be conserved :

Initial momentum = Final momentum

m(0) + M(0) = m(300) + Mv

\(v=-\dfrac{300m}{M}\\\\v=-\dfrac{300\times 0.005}{5}\\\\v=-0.3 \ m/s\)

Therefore, recoil velocity of the rifle is 0.3 m/s.

Hence, this is the required solution.

Answer:

200 m

Explanation:

Initial velocity- 0

final velocity= v

time= 10 seconds

to find final velocity

v= u + at

v= 0 + 4*10

v= 0 + 40

v= 40 m/s

to find distance

s= ut + 1/2at²

s= 0*10 + 1/2*4*(10)²

s= 1/2 *4*100

s=200m

Answer:

A centripetal force

Explanation:

The type of force in the given scenario is tension. The correct option is c.

Tension is defined in physics as the pulling force conveyed axially by a string, cable, loop, or similar material, or by every end of a rod, truss member, or similar three-dimensional object.

Tension can also be defined as the action-reaction pair of forces acting at each end of said elements.

Newton's second law states that the tension in the rope must equal the weight of the backed mass.

Tension, the normal force, and friction are all examples of contact forces.

Since the weight is not moving, the acceleration is zero. Even if the acceleration is not zero, this equals zero.

Thus, the correct option is c.

Explanation:

Acellus

Answer:

It would be cut in half.

Explanation:

If the momentum of the ball is cut into half, the velocity will also be halved.

The momentum of a body is the amount motion a body possess.

Momentum is given as;

       momentum= m x v

Given that;

 mass  = 1kg

 velocity  = 12m/s

Now find the momentum;

            momentum  = 1 x 12 = 12kgm/s

Halving the momentum = 6kgm/s

              mass = 1kg

 Momentum  = 1 x v

       6  = 1 x v

           v  = 6m/s

Answer :The answer is 3.1

Explanation: For this equation we solve it by dividing the voltage by the current flowing in the circuit. So the resistance formula is represented by

voltage/current.

Answer:

the velocity is 200

Explanation:

The resistance of the longer wire will be 54 ohms.

When a wire is drawn out through a die, its length increases while its cross-sectional area decreases, resulting in a change in its resistance. However, the resistivity of the material remains constant. According to Ohm's law, resistance is directly proportional to length and inversely proportional to cross-sectional area, so we can use the formula:

R = ρL/A

Where R is the resistance, ρ is the resistivity, L is the length, and A is the cross-sectional area.

Since the resistivity and density of the material are unchanged, we can assume that the wire's cross-sectional area is reduced by a factor of 3 when its length is tripled. Therefore, its new length is 3 times its original length, and its new cross-sectional area is 1/9 of its original value.

Thus, plugging in the given values into the formula:

Rnew = ρ(3L)/(A/9)

Rnew = 27ρL/A

Since Rnew = 27Roriginal, we can substitute Roriginal = 6 ohms into the equation to get:

Rnew = 27(6 ohms) = 162 ohms

However, we need to remember that the question asks for the resistance of the longer wire, not the change in resistance. Therefore, we need to subtract the original resistance from the new resistance:

Rlonger = Rnew - Roriginal

Rlonger = 162 ohms - 6 ohms

Rlonger = 156 ohms

Thus, the resistance of the longer wire is 156 ohms, or 54 ohms when rounded to one decimal place.

The upper-air patterns that support severe thunderstorms or tornadoes include a strong jet stream, low-level wind shear, high instability, and strong low-level moisture convergence. These conditions can interact to produce favorable environments for severe weather.

The upper-air patterns that would support a forecast for severe thunderstorms or tornadoes include:

1. Jet Stream: A strong jet stream, particularly one with a trough or dip in the pattern, can provide the necessary lift and wind shear for severe thunderstorms and tornadoes. The jet stream also aids in the transport of moisture and instability.

2. Low-Level Wind Shear: Wind shear, the change in wind speed and/or direction with height, is essential for the formation of supercell thunderstorms and tornadoes. Low-level wind shear can result from a southerly flow at the surface and westerly winds aloft, causing the air to rotate horizontally.

3. High Instability: An unstable atmosphere, characterized by warm, moist air near the surface and cooler, drier air aloft, promotes strong updrafts and severe thunderstorm development. The greater the instability, the stronger the updrafts and potential for severe weather.

4. Strong Low-Level Moisture Convergence: Converging winds at the surface can force moist air to rise, providing a source of energy for thunderstorm development. When low-level moisture convergence is strong, it can enhance the potential for severe storms and tornadoes.

In summary, the upper-air patterns that support severe thunderstorms or tornadoes include a strong jet stream, low-level wind shear, high instability, and strong low-level moisture convergence. These conditions can interact to produce favorable environments for severe weather.

1. The direction of the magnetic field at the center of the loop is perpendicular to the plane of the loop and follows the right-hand rule.

The right-hand rule states that if you curl the fingers of your right hand in the direction of the current flow in a loop, your thumb will point in the direction of the magnetic field at the center of the loop. The magnetic field lines are circular and perpendicular to the plane of the loop.

2. The expression for the magnitude of the magnetic field at the center of the arc can be calculated using the formula for the magnetic field due to a circular loop of wire. The expression is given by: B = (μ₀ * I) / (2 * r), where B is the magnetic field, μ₀ is the permeability of free space, I is the current in the loop, and r is the radius of the arc.

The magnetic field at the center of the arc formed by the right-angle bend in the wire can be calculated using the formula for the magnetic field due to a circular loop of wire. The magnetic field strength is directly proportional to the current in the loop (I) and inversely proportional to the radius of the arc (r). The permeability of free space (μ₀) is a constant value. By plugging in the values of current and radius, the expression for the magnitude of the magnetic field at the center of the arc can be determined.

3. The force per unit length between two parallel wires carrying current can be calculated using the formula: F/L = (μ₀ * I₁ * I₂) / (2 * π * d), where F/L is the force per unit length, μ₀ is the permeability of free space, I₁ and I₂ are the currents in the wires, and d is the distance between the wires.

The force per unit length between two parallel wires carrying current can be calculated using the formula above. The force is directly proportional to the product of the currents in the wires (I₁ and I₂) and inversely proportional to the distance between the wires (d). The permeability of free space (μ₀) is a constant value.

4. The force between two parallel wires depends on the direction of the currents. If the currents are in the same direction, the force is repulsive, and if the currents are in opposite directions, the force is attractive.

The direction of the currents in the two parallel wires determines the direction of the magnetic fields around the wires. When the currents flow in the same direction, the magnetic fields around the wires interact and result in a repulsive force between the wires. When the currents flow in opposite directions, the magnetic fields interact differently and result in an attractive force between the wires.

5. To find the current in the other wire when two parallel wires separated by a distance carry a force per unit length, the formula can be rearranged to solve for the current in the second wire, I₂ = (F/L) * (2 * π * d) / (μ₀ * I₁), where I₂ is the current in the second wire, F/L is the force per unit length, d is the distance between the wires, μ₀ is the permeability of free space, and I₁ is the current in the first wire.

By rearranging the formula for the force per unit length between two parallel wires, the current in the second wire (I₂) can be calculated. The force per unit length (F/L), the distance between the wires (d), and the current in the first wire (I₁) are known quantities, and the permeability of free space (μ₀) is a constant value.

While it is true that a dentist can use a special light during a teeth whitening procedure, it is not the light that actually changes the color of the teeth.

The light is simply a catalyst that activates a chemical reaction in the whitening gel or solution that is applied to the teeth.

Most teeth whitening products use a peroxide-based gel or solution, which breaks down into water and oxygen ions when it comes into contact with the teeth.

These oxygen ions then penetrate the enamel and dentin of the teeth, breaking apart the chemical bonds that cause tooth stains and discoloration.

The process of whitening teeth can take several treatments, with the use of a special light during each treatment to help speed up the chemical reaction.

So, in short, it is not the light itself that changes the color of Jayden's teeth, but rather the chemical reaction that is activated by the light.

The additional charge that flows to the positive plate from the 8 Volts battery is  12 x 10⁻³ Coulomb's.

We have an uncharged capacitor which is charged in two different ways using battery of two different voltages. Firstly, it is connected to the terminals of a 4.0 V battery, and 12 μc of charge flows to the positive plate. Then, the 4.0 V battery is disconnected and replaced with a 8.0 V battery

We have to determine the Additional charge that flows to the Positive plate from this 8 V battery.

Capacitance is the ability of an object to collect and store energy in the form of an electrical charge. Mathematically -

C = Q/V

According to the question, we have -

Electric potential of battery 1 = V[1] = 4 V

Charge flow from battery 1 to the positive plate = Q[1] = 12 x 10⁻³ C

Electric potential of battery 2 = V[2] = 8 V

Now, using the following relation, we will find Q[2] {Charge flow from battery 2 to the positive plate} →

V[1] / V[2] = Q[1] / Q[2]

Substituting the values -

Q[2] = (12 x 10⁻³ x 8)/4 = 24 x 10⁻³ C

Additional Charge that flowed to the positive plate →

Q[2] - Q[1] = 12 x 10⁻³ Coulomb's

Answer:

The net force acting on the car is zero.

Explanation:

From the question given above, the following data were obtained:

Mass (m) = 350 Kg

Velocity (v) = constant = 15 m/s

Net Force (F) =?

An object moving with a constant velocity is not accelerating. The acceleration of such object is zero. Thus, the net force acting on the object is also zero. This can further be explained as shown below:

Mass (m) = 350 Kg

Acceleration = 0 (since the velocity is constant)

Net Force (F) =?

Force (F) = mass (m) × Acceleration (a)

F = m × a

F = 350 × 0

F = 0

Thus, the net force acting on the car is zero.

Frictional forces are forces that oppose the relative motion of two surfaces in contact. Friction is created between two surfaces in contact as a result of the bumps and valleys on the surface.

The magnitude of the frictional force is proportional to the amount of force applied to the object and the coefficient of friction. There are two types of friction: static and kinetic. Static friction is the force that opposes the relative motion of two objects in contact that are not moving.

Kinetic friction is the force that opposes the relative motion of two objects in contact that are in motion. The properties of frictional forces are:

- It opposes motion
- It depends on the force between the surfaces
- It is a contact force
- It can cause wear and tear on surfaces
- It can be reduced by the use of lubricants


b) The coefficient of static friction between the tires and the road is 0.3. The automobile is moving at a speed of 60 km/hr. We need to find the shortest distance in which the automobile can be stopped. We know that the frictional force opposing the motion of the automobile is:

f = µN, where µ is the coefficient of static friction and N is the normal force.

The normal force acting on the automobile is equal to the weight of the automobile. The weight of the automobile is given by:

W = mg

where m is the mass of the automobile and g is the acceleration due to gravity.

The force required to stop the automobile is:

F = ma

where a is the acceleration of the automobile.

We know that the force required to stop the automobile is equal to the frictional force opposing the motion of the automobile.

f = F

µN = ma

µmg = ma

a = µg

The distance required to stop the automobile is given by:

d = v²/2a

where v is the initial velocity of the automobile.

Substituting the values, we get:

a = µg

a = 0.3 × 9.8 m/s²

a = 2.94 m/s²

v = 60 km/hr = 16.67 m/s

d = v²/2a

d = 16.67²/2 × 2.94

d = 48.06 m

Hence, the shortest distance in which the automobile can be stopped is 48.06 m.

Therefore, the velocity of the ball just before it hits the ground is approximately 22.1 m/s. Therefore, the closest value to this option is 21.0 m/s.

When a ball of mass 0.25 kg falls from a height of 50 m, we can calculate its velocity using the principle of conservation of energy. According to this principle, the sum of the potential and kinetic energy of an object remains constant.

Therefore, we can equate the potential energy at the initial height to the kinetic energy at the final velocity.Let's calculate the potential energy of the ball at the initial height

:Eg = mghEg = 0.25 kg × 9.81 m/s² × 50 m

Eg = 122.625 J

This is the energy that the ball has due to its position. As it falls, this energy is transformed into kinetic energy. At the moment the ball reaches the ground, all the potential energy has been transformed into kinetic energy

.Ek = 1/2mv²Ek = Egv² = 2Ek/mv = √(2Ek/m)

Let's plug in the values we obtained:Eg = 122.625 Jm = 0.25 kgv = √(2Ek/m)
