Answer:
the resulting angular speed after she pulls her hand inwards in (rad/s) is 27.02 rad/s
Explanation:
Given that :
the initial angular speed
Initial rotational inertia
Final angular speed
Final rotational inertia
According to conservation of momentum :
Initial momentum = final momentum
To rad/s ; we have:
Therefore the resulting angular speed after she pulls her hand inwards in (rad/s) = 27.02 rad/s
Answer:
Explanation:
A) Initial kinetic energy of proton
B) How close does the proton get to the line of charge?
Potential energy and kinetic energy are related as:
Change in voltage is
