If I drop a paper clip from rest and it falls freely until it hits the ground with a speed of 30 m/s,we ae to find the time taken for the ball to drop. To do that we will use the equation of motion v = u + gt

v is the final velocity = 30m/s

u is the initial velocity = 0m/s (the object drops from rest)

g is the acceleration due to gravity = 9.81m/s²

time is the time taken

Substituting the given parameters into the formula;

30 = 0 + (9.81)t

30 = 9.81t

t = 30/9.81

t = 3.06secs

Hence it will take the object 3.06secs in free fall

A net forward force as well as gravitational force pulls the marble downwards whereas frictional force slows it down.

A force is an agent which causes a change in the motion or state of an object.

Forces are of two types:

Andrew applies force on the marble causing it to move.

When Andrew pokes the marble, he gives it net forward force. As the marble rolls down the ramp, gravitational force pulls it down.

The movement of the marble is slowed down by frictional force from the ramp.

Therefore, a combination of applied force and gravitational force moves the marble forward, while frictional force slows it down.

The orbital speed of spacecraft A is one-half that of craft B.

A spacecraft needs to move at a speed of roughly 8 kilometres (5 miles) per second to maintain a circular orbit just above the Earth's atmosphere. A faster launch velocity will cause the spacecraft to swing farther away from Earth. If it is increased to 11 km/s (7 miles/s), the spaceship will completely depart the planet.

A satellite's orbital speed is influenced by the mass of the planet and how far it is from the planet's centre. The third law of Kepler states that the square of a satellite's orbital period is proportionate to the cube of the distance of the satellite from the planet's centre:

T is the orbital period, and r is the separation from the planet's centre (T2 r3).

To calculate the ratio of their orbital speeds, we can apply the equation above:

Spacecraft A and B's orbital speeds are given by v_A and v_B, respectively, while their distances from the planet's centre are given by r_A and r_B, respectively.

r_B = 2r_A

This is substituted into the equation above to produce the result: v_A / v_B = r_B / r_A = 2.

Answer:

A) 80 N

Explanation:

The closer the particles get, the stronger the Coulomb force, which elongates choices C and D. The Coulomb force is inversely proportional to the distance squared. If the distance is cut in half, the force is multiplied by the reciprocal of (1/2)^2, which is 4. Multiplying it out, 20 times 4 is 80 N.

The Coulomb force if the same particles are separated by a distance of 6 meters is 222.221 N.

Coulomb force is also known as electrostatic force is the force of attraction or repulsion of particles or objects because of their electric charge. It is given by the formula,

\(F = k \dfrac{q_1q_2}{r^2}\)

Where

F = electric force

k = Coulomb constant = 8.9875517923×10⁹ kg⋅m³⋅s⁻²⋅C⁻²

\(q_1, q_2\) = charges

r = distance of separation

We know that the distance between the two particles is 12 meters while the force between the two particles is 20N, therefore, the Coulombs force can be written as,

\(F = k \dfrac{q_1q_2}{r^2}\\\\20 = k \dfrac{q_1q_2}{20^2}\\\\k {q_1q_2} = 20 \times 20^2\\\\k {q_1q_2} = 8000\)

Now, if the distance between the two particles is reduced to 6, the force will be,

\(F = k \dfrac{q_1q_2}{r^2}\\\\F = \dfrac{8000}{6^2}\\\\F = 222.221\rm\ N\)

Hence, the Coulomb force if the same particles are separated by a distance of 6 meters is 222.221 N.

The weakest intensity of red light that Jacob is able to see is his threshold for that light.

This refers to the minimum amount of red light that is needed for Jacob to perceive it. The threshold for any given sense is the lowest level of stimulation that is needed for the sense to be activated.

The threshold for any given sense is the minimum level of stimulation required to activate that sense. In the case of Jacob's vision, his threshold for seeing red light refers to the minimum amount of red light that is needed for him to perceive it. This means that if the intensity of the red light falls below his threshold, he would not be able to see it.

The concept of threshold is important in understanding how our senses work. Our senses are constantly bombarded with stimuli from the environment, but we are not aware of all of them. The stimuli need to reach a certain level of intensity or quality to cross the threshold and be perceived by our senses. This is why we may not notice a faint sound or a dim light, but we can easily hear a loud noise or see a bright light.

Knowing the threshold of a sense can also help in understanding the limitations of that sense. For example, if a person has a high threshold for a particular sense, it may mean that they are less sensitive to stimuli related to that sense. Conversely, a person with a low threshold for a sense may be more sensitive to stimuli related to that sense.

Answer:

the filling stops when the pressure of the pump equals the pressure of the interior air plus the pressure of the walls.

Explanation:

This exercise asks to describe the inflation situation of a spherical fultball.

Initially the balloon is deflated, therefore the internal pressure is equal to the pressure of the air outside, atmospheric pressure, when it begins to inflate the balloon with a pump this creates a pressure in the inlet valve and as it is greater than the pressure inside, the air enters it, this is repeated in each filling cycle, manual pump.

When the ball is full we have two forces, the one created by the external walls and the one aired by the pressure of the pump, these forces are directed towards the inside, but the air molecules exert a pressure towards the outside, which translates into a force. When these two forces are equal, the pump is no longer able to continue introducing air into the balloon.

Consequently the filling stops when the pressure of the pump equals the pressure of the interior air plus the pressure of the walls.

The soccer ball is 38/5 or 7.6 meters high after 2 seconds.

The equation you've given is a quadratic function that models the height of the soccer ball over time, considering gravitational pull.

To find the height of the ball after 2 seconds, we substitute t = 2 into the equation:

h(t) = -4.9t² + 13.1t + 1.

Therefore,

h(2) = -4.9*(2)² + 13.12 + 1

= -4.94 + 26.2 + 1

Answer:

the motion of an object at a constant speed along a circular path is known as Uniform circular motion

Answer:

Hope my answer is understandable to you.

The magnitude of the radial force on the mass can be calculated using the formula:

Fr = mrω²

Where Fr is the magnitude of the radial force, m is the mass, r is the radius of the circular path, and ω is the angular speed.

In this case, we know that the mass is 4.00 kg and the angular speed is 5.00 rad/sec. To find the radius of the circular path, we can use the formula for linear speed:

v = ωr

Where v is the linear speed and r is the radius.

We know that the linear speed is 5.00 m/sec and the angular speed is 5.00 rad/sec, so we can plug these values in and solve for r:

5.00 m/sec = 5.00 rad/sec x r

r = 1.00 m

Now we can plug in the values for m, ω, and r into the formula for the magnitude of the radial force:

Fr = (4.00 kg) x (5.00 rad/sec)² x (1.00 m)

Fr = 100 N

Therefore, the magnitude of the radial force on the mass is 100 N.

The charge of the particle must be +10.2 μC for it to remain stationary in the downward-directed electric field of magnitude 700 N/C.

To determine the charge required for the particle to remain stationary in a downward-directed electric field, we can equate the electric force with the gravitational force acting on the particle. The electric force experienced by a charged particle in an electric field is given by the equation: electric force = charge × electric field.

The gravitational force acting on the particle can be calculated using the equation: gravitational force = mass × acceleration due to gravity. Since the particle remains stationary, the electric force and gravitational force must be equal in magnitude but opposite in direction. Therefore, we can set up the equation:

charge × electric field = mass × acceleration due to gravity

Given that the mass of the particle is 1.46 g (which is equivalent to 0.00146 kg) and the electric field magnitude is 700 N/C, and the acceleration due to gravity is 9.80 m/s², we can solve for the charge:

charge = (mass × acceleration due to gravity) / electric field

       = (0.00146 kg × 9.80 m/s²) / 700 N/C

       = 0.00002076 C

       ≈ 20.8 μC (rounded to one decimal place)

The charge of the particle required for it to remain stationary in the downward-directed electric field is approximately +10.2 μC (since the charge should be positive to oppose the electric field).

Explanation:

Answer:

orce = rate of change of momentum which is m a if the mass is constant

10 Newtons = change of momentum/0.10 second

so change of momentum = 1 kg m/s

by the way the change in speed would be 1/5 = .2 m/s

Explanation:

If a 5-kg object experiences a 10-N force for a duration of 0. 10-second then the impulse exerted by the force on the object would be 1 Ns, and the change in the momentum would be  1 Ns.

It can be defined as the product of the mass and the speed of the particle, it represents the combined effect of mass and the speed of any particle, and the momentum of any particle is expressed in Kg m/s unit.

As given in the problem If a 5-kg object experiences a 10-N force for a duration of 0. 10-second then we have to find out what the impulse exerted by the force on the object.

P = force × time
