Use Newton’s second law (Fnet = ma) to answer each question. SHOW ALL YOUR WORK, including the units! 1N = 1 kg m/s2. A rocket accelerates 2.0 m/s2 when a force of 12.0 Newtons is applied to it. What is the mass of the object?

How does the electric potential energy between two charged particles change if one particle is reduced by a factor of 3? a. increased by a factor of 3 b. it is decreased by a factor of 9 c. it is reduced by a factor of 3 d. it is increased by a factor of 9

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.

What ia the energy of an object because of its potential and kinetic energies
