In a lab investigation one group of students group A measures the speed of a 0.1 kg toy car to be 2.5 m/s at the bottom of the ramp. another group of students Group B measures the speed of the car to be 3 m/s at the bottom of the ramp. The car's starting position at the top of the ramp is 1 M High 1.calculate the kinetic energy of the car for group A.

2. calculate the kinetic energy of the car for Group B

When fat comes in contact with sodium hydroxide, it produces soap and glycerin. determine whether this is a physical change or a chemical change. explain your answer

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.
