Explanation:
A positive point charge Q is fixed on a very large horizontal friction less tabletop. A second positive point charge q is released from rest near the stationary charge and is free to move.
As per the law of conservation of energy the change in kinetic energy is equal to the change in potential energy.
The mathematical expression for the conservation of energy is given by :
On solving the above equation, we get the value of v as :
In the above expression, as the term increase, as increases, the value of decreases. So, the correct option is (B) "As it moves farther and farther from Q, its speed will increase".
The problem about describes a perfectly inelastic collision. We are tasked to find the initial velocity of an object having a mass of 6 kg moving due west. It is given in the problem that after collision the cart sticks together and it stops. Thus, the final mass is the sum of the two cart and the final velocity is zero. For a perfectly inelastic collision,
m1v1-m2v2=vf(m1+m2)
By Substitution,
3(4)-6(v2)=0
6v2=12
v2=2
Therefor, the initial velocity if a 6 kg cart is 2 m/s
Answer:
False
Explanation:
Using your opposite hand will strengthen neural connections in your brain, and even grow new ones. It’s similar to how physical exercise improves your body’s functioning and grows muscles
The choices above are social psychology terms
that help describe the people’s actions in their everyday interaction with
people. The sentence example is:
Those computer geeks are all the same.
They
spend all day playing video games and programming their computers to serve them
breakfast. I don't think I've ever seen one reading a real book or throwing a
baseball. Why, they're almost like machines!
