Answer:

Plug in the given values and solve for the final velocity. Remember, when the ball is on the ground it has a height of zero.

An elephant and a mouse would both have zero weight in gravity-free space. If they were moving toward you with the same speed, w
Dovator [93]

The elephant and the mouse having zero weight in a gravity free space will not bump into you at the same effect.

<u>Explanation: </u>

When both are in a gravity free space, the weights are zero, as we know that the\text {weight of the body}=\text {mass of the body} \times \text {acceleration due to gravity}

\text {here, the weight of elephant}=\text {mass of elephant } \times \text {zero gravti} y=zero

\text {similarly,weight of mouse}=\text {mass of mouse } \times \text {zero gravity}=zero

But when they will acquire the speed of same magnitude, say v, their different masses will acquire different momentum, which will make the difference in effect while bumping.  

\text { momentum of elephant }=\text { mass of elephant } \times v  \text { momentum of mouse = mass of mouse } \times v

And as we know \text { mass of elephant }>\text { mass of mouse }  Therefore, effect of impact by elephant will be more than that of mouse . An elephant breaking into you will take you back faster than a mouse in space hits you.

Two pulses are moving along a string one pulse is moving to the right and the second is moving to the left. Both pulses reach po
MatroZZZ [7]

Answer:

Constructive interference

Explanation:

- This is an example of a standing wave produced when two ends of a string are oscillated in the same plane. The displacement of of point on two ends oscillates vertically.

- We are given that two pulses move along the string each coming towards each other and meet at a common point ( P ).

- Each pulse have their own magnitude or displacement in the vertical plane. If the pulses are to meet at a common point at the same instant, then they interfere with each other constructively.

- Where constructive interference of two pulses is the addition of magnitudes of induvidual pulses and form a single puls of the constructed magnitude.

    magnitude ( New pulse ) = magnitude (Pulse 1) + magnitude (Pulse 2)
