A 1500 pound car is stopped in traffic on a hill that is at an incline of 10. The force that is required to keep the car from rolling down the hill will be 1133.53 N.

When all the forces that act upon an object are balanced, then the object is said to be in equilibrium motion. The forces are considered to be balanced if the rightward forces are balanced by the leftward forces and the upward forces are balanced by the downward forces.

It can be observed from the diagram that in order resist the car to rolling down the hill we need to apply an equal and opposite force against the inclined force( that is mgsin(x)) to form an equilibrium position because rolling is associated with horizontal forces hence we need to apply force against the force which can drive down the car .

mass = 1500 pound = 680.39 kg

sin(10) = 0.17

F (counter force ) = m*g*sin(x)

                             = 680.39  * 9.8 * 0.17

                             = 1133.53 N

(a) The potential difference between the plates. The capacitance of the parallel plate capacitor is given by,

C = ε₀ (A/d), where A = 9.60 cm² = 9.60 × 10⁻⁴ m², d = 2.30 mm = 2.30 × 10⁻³ m and ε₀ is the permittivity of air or the free space which is 8.85 × 10⁻¹² F/m. Then,

C = 8.85 × 10⁻¹² (9.60 × 10⁻⁴/2.30 × 10⁻³) = 36.9 × 10⁻¹² F. Voltage, V = 9.80 V

Then, Q = VC = 9.80 × 36.9 × 10⁻¹² C.

Now, the distance between the plates, d' = 8.60 mm = 8.60 × 10⁻³ m, then the capacitance of the capacitor will be,

C' = 8.85 × 10⁻¹² (9.60 × 10⁻⁴/8.60 × 10⁻³) = 0.986 × 10⁻¹² F.

The charge on the capacitor remains constant. Therefore, the potential difference between the plates will be

V' = Q/C' = (9.80 × 36.9 × 10⁻¹²) / 0.986 × 10⁻¹² = 370 V

(b) The initial stored energy is given by,

U = (1/2) QV = (1/2) CV² = (1/2) (8.85 × 10⁻¹²) (9.80)² (9.60 × 10⁻⁴/2.30 × 10⁻³)= 1.12 × 10⁻⁸ J

(c) The final stored energyThe final stored energy is given by,

U' = (1/2) C'V'² = (1/2) (0.986 × 10⁻¹²) (370)²= 1.37 × 10⁻⁷ J

(d) The work required to separate the platesThe work done in separating the plates is given by the difference between the final stored energy and the initial stored energy.

W = U' - U = (1.37 × 10⁻⁷) - (1.12 × 10⁻⁸) J= 1.25 × 10⁻⁷ J

Capacitors are one of the most used passive components in electronic circuits. Capacitors store electrical energy and release it when needed. It is used in smoothing circuits, filters, and so on. A capacitor is a passive electronic component that stores energy in an electric field, which is then used in electronic circuits. When a potential difference is applied across the terminals of the capacitor, an electric field develops across the capacitor's plates. One plate gains positive charges and the other gains negative charges, which is separated by a dielectric material. Capacitance is defined as the amount of charge stored per unit of potential difference, which is measured in farads. It depends on the distance between the plates, the area of the plates, and the dielectric material between them. When the plates are pulled apart, the distance between them increases, and so does the capacitance. The potential difference remains constant, and the charge stored on the capacitor is also constant. The work done in separating the plates increases the stored energy of the capacitor.

Hello your question is poorly written hence I will just give the difference between conduction and convection

answer :

Conduction occurs when there is direct contact between solids and source of heat. while convection occurs when there is transfer of thermal energy due to movement of liquid or gas

Explanation:

when a pot of water is placed on a hot stove the pot is heated through conduction because the metal pot is in direct conduct with the heat from the stove ( which is the primary source of heat in this scenerio ).

while the heat transfer from the hot pot to the water is executed through convection this is because heat transfer via convection requires the movement of liquid or gas.  as the warmer liquid moves over to the top the cooler liquid goes below inside the pot that way the whole liquid becomes warm .

The kinetic energy of an object is the energy that is associated with its motion. The average kinetic energy of the particles that make up an object is a measure of the temperature of the object.

What is kinetic energy?

Kinetic energy is the energy that an object possesses due to its motion. Any object that is moving has kinetic energy. The amount of kinetic energy that an object has depends on its mass and its velocity. The equation for calculating the kinetic energy of an object is KE = 0.5 * m * v^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity (speed) of the object.

The correct answer is A: the average kinetic energy of the particles that make up an object.

The kinetic energy of an object is the energy that is associated with its motion. The average kinetic energy of the particles that make up an object is a measure of the temperature of the object. The higher the temperature of an object, the greater the average kinetic energy of its particles.

Option B describes potential energy, which is the energy stored in an object due to the position of its particles. This energy can be converted into kinetic energy if the object is allowed to move.

Option C describes thermal energy, which is the total energy of all the particles within an object, including both kinetic and potential energy.

Option D describes heat transfer, which is the transfer of thermal energy from one object to another due to a temperature difference.

Where the digit that came after the 5 was a 2, so we rounded down.

Our eyes assume that light is traveling in a straight line. This is called the "law of rectilinear propagation of light." This law states that light travels in a straight line unless it is reflected, refracted, or absorbed by an object.

When light hits an object, it can either be absorbed, reflected, or refracted. If the object is opaque, the light will be absorbed and no light will pass through. If the object is reflective, the light will bounce off of it at the same angle it hit the object. If the object is transparent, the light will pass through it, but it may be refracted, or bent, as it passes through.

Our eyes use the law of rectilinear propagation of light to create an image of the world around us. When light hits the retina in the back of our eye, it creates an image that is sent to the brain. The brain then interprets this image and creates our perception of the world around us.

In conclusion, our eyes assume that light is traveling in a straight line, unless it is reflected, refracted, or absorbed by an object. This assumption is based on the law of rectilinear propagation of light and is used to create an image of the world around us.

Explanation:

The question says that, "A spring is elongated 30 centimeters when we exert a force of 24 N on it a) calculate the value of the spring constant b) calculate the elongation of the spring when applying a force of 60 N"

Given that,

Force exerted on the spring, F = 24 N

Elongation in the spring, k = 30 cm =0.3 m

(a) We know that, the force on the spring is given by :

F = kx

Where

k is spring constant

So,

\(k=\dfrac{F}{x}\\\\k=\dfrac{24}{0.3}\\\\k=80\ N/m\)

(b) When F = 60 N,

\(x=\dfrac{F}{k}\\\\x=\dfrac{60}{80}\\\\x=0.75\ m\\\\x=75\ cm\)

Hence, this is the required solution.

The formula for the horizontal range is dependent on the initial velocity, angle of projection, and acceleration due to gravity. Therefore, the formula is \(range = velocity\;horizontal \times 2V0y / g \times sin\theta\)

The range of a projectile refers to the horizontal distance it covers during its flight. To derive a formula for the horizontal range of a projectile, we can use the kinematic equations.

The horizontal motion of a projectile is constant, and we can use the equation:

distance = velocity × time

In the horizontal direction, the initial velocity of the projectile remains constant throughout its flight. Thus, the horizontal distance traveled can be calculated as:

range = velocity horizontal × time

To determine the time, we can use the vertical motion equation:

\(y = V0y \times t + 1/2 gt^2\)

Where y is the vertical displacement, V0y is the initial vertical velocity, g is the acceleration due to gravity, and t is the time.

We know that at the maximum height, the vertical velocity is zero. Thus, the time taken to reach maximum height is:

t = V0y / g

The time taken for the projectile to reach the ground from the maximum height is also equal to t.

Substituting this value of t into the horizontal distance equation gives:

\(range = velocity\;horizontal \times 2V0y / g \times sin\theta\)

where θ is the angle of projection.

In summary, the horizontal range of a projectile can be derived using kinematic equations by considering the horizontal motion and vertical motion of the projectile. The formula for the horizontal range is dependent on the initial velocity, angle of projection, and acceleration due to gravity.
