I think the answer is c) 1
Hope it helps and have a good day
Considering the magnetic force is providing the centripetal force,
we get, mv^2/r = qvB
so, r = mv/qB
as the Kinetic energy, K of the particle is given by.5mv^2
so, v = sqrt(2K/m)
substituting the in radius equation,
<span>r = m*sqrt(2K/m)/qB
r = sqrt(2Km)/qB</span>
Answer:
Explanation:
Because friction is always present, the actual mechanical advantage of a machine is always less than the ideal mechanical advantage.
Answer:
In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each component. ... In a series circuit, every device must function for the circuit to be complete. If one bulb burns out in a series circuit, the entire circuit is broken.
Hi there!
Recall the equation for kinetic energy:
KE = Kinetic energy (J)
m = mass (kg)
v = velocity (m/s)
Plug in the given values:
