A 0.25 kg object is experiencing a net force of 15 N while traveling in a circle at a velocity of 8.0 m/s. What is the radius of its motion?

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

there are no atoms
