6. Give an example of an energy transformation from nuclear to electromagnetic.

1 answer:

7 0

An example of an energy transformation from nuclear to electromagnetic is: The sun transforms nuclear energy into ultraviolet, infrared, and gamma energy all forms of electromagnetic energy.

Explanation: The change of energy from one form to another is known as energy transformation. In every second energy transformations is constantly occurring everyplace.

Energy is transferable but it cannot be generated or destroyed. Electrical, mechanical, electromagnetic, nuclear, and chemical are some forms of energy.

The energy stored in the nucleus of an atom is known as Nuclear energy. Huge amounts of energy gets released at the time when nuclei combines or breaks. The gravitational collapse of hydrogen clouds produce heat and pressure that helps in activating Nuclear Fusion.

a baseball is hit straight up into the air. If the initial velocity was 20 m/s, how high will the ball go?How long will it be un

AleksAgata [21]

1) The motion of the ball is an uniformly accelerated motion, with constant acceleration equal to $g=-10 m/s^2$ (the negative sign means it is directed towards the ground).

For an uniformly accelerated motion, we can use the following relationship:
$2gh=v_f^2-v_i^2$
where h is the maximum height reached by the ball, $v_i = 20 m/s$ is its initial velocity and $v_f$ the velocity of the ball when it reaches the maximum height. But $v_f=0$ (when the ball reaches the maximum height, it stops before going down, so its velocity at that moment is zero), so we can use the relationship to calculate h, the maximum height:
$h=- \frac{v_i^2}{2g} =- \frac{20 m/s)^2}{2 \cdot (-10 m/s^2)} =20 m$

2) We can find the time the ball takes to return to the ground by requiring that the space covered by the ball returns to zero:
$S(t)=0$
where for an uniformly accelerated motion,
$S(t)=v_i t + \frac{1}{2} gt^2 =0$
By solving this, we have two solutions: one is t=0, which corresponds to the moment the player hits the ball, the second one is
$t=- \frac{2 v_i}{g}=- \frac{2 \cdot 20 m/s}{-10 m/s^2}=4 s$
so, the ball returns to the ground after 4 s.

3) The velocity of the ball when it returns to the ground is given by:
$v(t) = v_i +gt=20 m/s + (-10 m/s^2)(4 s)=-20 m/s$
where the negative sign means the ball is going downwards.

You push a heavy crate down a ramp at a constant velocity. Only four forces act on the crate. Which force does the greatest magn

Brilliant_brown [7]

The friction force does the greatest magnitude of work on the crate

Consider all four forces. The normal force does no work at all, since there is no motion in the direction of that force, perpendicular to the ramp. The force of gravity is smaller than the force of friction, since you still need to push the crate to get constant velocity. The force of you pushing is also smaller than the force of friction, since you are moving down a ramp, and are therefore assisted by gravity. Therefore the force doing greatest magnitude of work is the force of friction. Note that, even though the frictional work is negative, it still has the greatest magnitude
