Choice - B is the correct one.
At the top of the arc, at one end of the swing:
-- it's not going to get any higher, so the potential energy is maximum
-- it stops moving for an instant, so the kinetic energy is zero
At the bottom of the arc, in the center of the swing:
-- it's not going to get any lower, so the potential energy is minimum
-- it's not going to move any faster, so the kinetic energy is maximum
Answer:
Explanation:
As we know that bullet strike the block and fix in it
so here if bullet and box is taken as a system then there is no external force on it
so here the initial momentum of bullet and block must be equal to final momentum of bullet and block
so here we have
now we have
now from above equation we have
This might be totally wrong cause i have no context as to what this question is referring to but a ceiling fan uses magnets and electricity to rotate
Use Newton’s second law: F=ma
m= 250kg. a= 750ms-2
F= 250 x 750 = 187 500N
<span>The ability to navigate, hunt, and communicate by electric current in water most likely helps make up for the effect of vision. The answer to your question is VISION.
</span>If fish live in a dark, murky water, that means that their sense of vision is affected. In dark, murky water they could not see anything. So, fish that lives in this kind of water developed the ability to <span>o navigate, hunt, and communicate by electric current in water. This ability is known as electroreception. Among fish, electroreception is present in some sharks and rays, and electric eels.</span><span>
I hope that this is the answer that you were looking for and it has helped you.
