Which of the following statements are correct about different unit combinations? There is more than one correct answer; points are deducted for wrong answers. Kinetic energy uses different units than other forms of energy. Magnetic field can be measured in Volts per meter, The units for force times distance ("Work") are the same as the units for momentum. Ohms are equivalent to Watts per {Ampere squared}. The units for thermal energy are the same as those for kinetic energy. The units for momentum times units for velocity some out the same as units for electrical energy. Momentum has the same untis as speed. Joules is the same as Coulombs times Volts. The force due to gravity is measured in different units than the electrostatic force.
