Answer:
502.2 m/s
Explanation:
initial velocity, u = 0 m/s
Let the final speed is v.
acceleration, a = 6.2 x 10^5 m/s^2
time taken, t = 8.10 x 10^-4 s
The muzzle speed is the final speed.
Use first equation of motion
v = u + a t
v = 0 + 6.2 x 10^5 x 8.10 x 10^-4
v = 502.2 m/s
Thus, the muzzle speed of the bullet is 502.2 m/s.

When two spheres, each with charge Q, are positioned a distance Rapart, they are attracted to ... doubled, the electric-force between the two spheres
True.
A nanometer is a unit of mass, whereas a nanosecond is a unit of time. To convert 1.3 hours to minute, you would multiply by 1 h / 60 min. Kilometer is a unit of length, whereas kilogram is a unit of mass. True.
took longer to complete one oscillation, that means its PERIOD increased, and the distance between the peaks of the graph would be longer.
line would be less. the period of oscillation would have any effect on the graph
