the acceleration of an object is 10 m/s2. if the object completed its acceleration in 2 seconds in the intentional velocity was 5 m/s, what was the final velocity

Which subatomic particle has a negative charge

Why is the use of carbon-14 limited

The protons in a nucleus are approximately 2 ✕ 10^−15 m apart. consider the case where the protons are a distance d = 1.93 ✕ 10^−15 m apart. calculate the magnitude of the electric force (in n) between two protons at this distance.
