Answer:
v = ((M(√2gH)/3m)
Explanation:
Initial Moment of Inertia= Moment of Inertia of Rod
I = (ML²)/3
Linear Velocity of moveable end of the rod, just before collision is given by = v = (√2gH)/L
Initial Angular Momentum, about the point of the suspension:
Li= Iw = {(ML²)/3} . {(√2gH)/L} = {ML(√2gH)}/3
Final Angular Momentum = Li = mvl, where 'v' is the speed of the mass 'm' after the collision
Since the collision is elastic, all momentum will be conserved, which means
Initial Angular Momemtum = Final Angular Momentum
{ML(√2gH)}/3 = mvL
solving for v = {(M)/3m} . {(√2gH)/L}
Answer:
The end of the neutral rod which is the closest part to the charged rod would acquire a negative charge.
Explanation:
One of the rods is positively charged and one of them is neutral.
And the important part is that <u>they do not touch one another</u>, but get close to each other.
In this case, the end of the neutral rod which is the closest part to the charged rod would acquire a negative charge. This is because of the Coulomb's Law. The opposite charges exert an attractive force to each other. The positive charges attract the negative charges on the neutral rod.
<span>Ice wedging is caused by water freezing and thawing. During this process of conversion of the water into ice the water is expanded and crack in the ground is formed. These cracks are formed duing the winter, when the water freezes, expands and the enlarges the cracks. In summer, when the ice melts more water is accumulated in the cracks and the process repeats.</span>
Answer: c) Positive acceleration describes an increase in speed; negative acceleration describes a decrease in speed.
Hey
On Earth, you can move or you can not move. if you are moving 50 mph that means relative to Earth (not the Andromeda galaxy). When you start moving (accelerating) you are now moving relative to Earth. when you start slowing down (decelerating [most scientists just say you have negative acceleration]) you are starting to match your velocity to Earth's velocity.
Hope it helped and made any sence at all.
