Solve for the Electric field of a point charge q, with a value of 2.9 nC and a distance of 2.4 m
Find the charge of a test charge with an electric field of 6.0 x 10⁻⁶ N/C and a force of 0.25 N
2 charged particles reacted with a force of 0.31 N with a distance of 1.5 cm, the 2nd charge contains 54 nC. Find the value of the first charge.
A washing machine is spinning at 5 rev/s at the time you open the lid and the motor disengages. The machine’s agitator in the center of the tub then begins to slow down. You observe that it makes 10 revolutions before coming to a stop. Assume that the angular acceleration is constant at all times.
a) What is the angular acceleration of the agitator in this process?
b) How long does it take the agitator to stop?
1 decibel at 500 nm is 100 W, what is the number of watts at 550 nm?
If a Saturn V rocket with an Apollo spacecraft attached had a combined mass of 3.1 × 105 kg and reached a speed of 11 km/s, how much kinetic energy would it then have?
The only force acting on a 2.8 kg canister that is moving in an xy plane has a magnitude of 5.8 N. The canister initially has a velocity of 4.4 m/s in the positive x direction, and some time later has a velocity of 6.7 m/s in the positive y direction. How much work is done on the canister by the 5.8 N force during this time?
Two point charges are placed as follows: charge q1 = -1.50 nC is at y = +6.00 m and charge
q2 = +3.20 nC is at the origin. What is the total force (magnitude and direction) exerted by
these two charges on a negative point charge q3 = -5.00 nC located at (2.00 m, -4.00 m)?
