If you're holding the apple at your waist, lift it to your mouth.
Potential energy relative to any level is proportional to its height
above that level. Increase that height, and you've increased the
potential energy.
Since energy is conserved ... it never magically appears or
disappears ... you need to tell where that extra energy for the
apple came from.
It's exactly the work you did ... the force of your muscles acting
through the distance you raised the apple ... that became the
additional potential energy that the apple gained.
The primary sex organs for men are called testes and ovaries for the women. They produce sex cells called gametes and they secrete sex hormones.
There’s a first
“clump”/drum beat every half second. That clump will travel about 170m in half
a second. Someone 170m away would do their “clump” as the second “clump” was
taking place. I think. <span>

Answer:
3/5 v
Explanation:
The computation of speed will the alpha particle have after the collision is shown below:-
In a perfectly elastic the kinetic energy and collision the momentum are considered.
The velocity of the particles defines the below equation:
As we know that
Here, we consider A is the alpha particle and B is the proton and now by the above values we can solve the equation which is below:-
Therefore the correct answer is
