Answer:
orbital speed of the electrons in their orbit will increase
Explanation:
As we know that centripetal force for electrons will be due to electrostatic attraction force of electron.
So it is given as
so we have
now on the left side if the force of attraction will increase and hence there must be the change in that part of equation
So here at the same position the speed of the electron
So we can say that correct answer will be
orbital speed of the electrons in their orbit will increase
The total momentum before and after the collision must be conserved.
- Let's start from the end: at this point, both cart and laundry bag are moving together, with a total mass of (m1+m2) and velocity 2.6 m/s. Therefore, the total momentum is
- The momentum must be conserved, so the initial momentum must be equal to this value:
- At the beginning, the cart is stationary, so its momentum is zero. There is only one momentum, the one of the bag, which has a mass of 20 kg and unknwon velocity vi:
- So, using the conservation of momentum we find
and from this, the initial velocity of the laundry bag:
