The ball was kicked in the air and it iss about to hit the . if horizonta componenet of its final velocity is 10m/s and vertical component of its final velocity is -10m/s .what is the magnotide of th final vellocity of the ball?

Answers

Answer:

The total velocity of the ball will be 14.14 m/s.

Explanation:

Horizontal Velocity component = 10 m/s

Vertical Velocity component = -10 m/s

Total velocity of the ball will be found from the following equation:

(Total velocity) ^2 = (Horizontal Velocity) ^2 + (Vertical Velocity) ^2

Total Velocity ^2 = 10^2 + (-10)^2

Total Velocity^2 = 100 + 100

Total Velocity = $√(200)$

Total Velocity = 14.14 m/s

If the distance is halved and the charges of both particles are doubled, the force is ________ as great.

Answers

If the distance is halved and the charges of both particles are doubled, the force is 16 times as great.

Coulomb's Law

According to Coulomb's law, the electrostatic force between two charges is given by;

$F=k(q_1 q_2)/(r^2)$

Where 'k' is the Coulomb's constant.

If the charges of both particles are doubled and the distance is halved, the new force will be;

$F\,'=k(2q_1 * 2q_2)/((r/2)^2)=k (4* 4* q_1 q_2)/(r^2) =16\,F$

So, the new force will be 16 times greater than the old force.

Answer:

The new force is 16 times of the initial force.

Explanation:

The electric force between charges is given by :

$F=(kq_1q_2)/(r^2)$

If the distance is halved, d' =d/2 and charges are doubles, $q_1'=2q_1\ \text{and}\ q_2'=2q_2$

New force becomes,

$F'=(kq_1'q_2')/(r'^2)\n\nF'=(k(2q_1)(2q_2))/((d/2)^2)\n\nF'=16* (kq_1q_2)/(r^2)\n\nF'=16F$

So, the new force is 16 times of the initial force.

Two similar sized stones one heavy and one light dropped from the same height into a pond explain why the impact of the heavy stone would produce with a higher amplitude than the impact of the light stone would

Answers

The impact of the heavy stone would produce with a higher amplitude than the impact of the light stone would because of having high potential energy.

What is gravitational potential energy?

An object's gravitational potential energy is described as the energy it would have had if it had defied gravity and risen to a certain height. Due to having only magnitude and no direction, it is a scalar quantity with SI unit of Joule.

Let, the mass of the heavy stone is m₁ and mass of the light stone is m₂ (m₁ > m₂). Both of them are dropped from same height h.

Then, gravitational potential energy of heavy stone is, V₁ = m₁gh.

And, gravitational potential energy of lighter stone is, V₂ = m₂gh.

Where, g = acceleration due to gravity.

Now, as m₁ > m₂; V₁> V₂

Due to having more potential energy, when the stones are dropped into a pond from same height, the heavy stone would produce with a higher amplitude than the impact of the light stone would.

in energy point of view, the larger stone had more potential energy before dropping. impacting the water, the larger one, having more kinetic energy which changed from potential energy, tranfered energy to the water and formed wave. the amplitude of the wave indicate the energy of the wave. more energy more amplitude.
