A96.1 kg man sits on the stern of a 6 m long boat. the prow of the boat touches the pier, but the boat isn’t tied. the man notices his mistake, stands up and walks to the boat’s prow, but by the time he reaches the prow, it’s moved 3.66 m away from the pier. assuming no water resistance to the boat’s motion, calculate the boat’s mass (not counting the man). answer in units of kg.

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

How many neutrons does plutonium -196 with an atomic number of 78.

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
