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.

A generator has a 46-turn coil with an area of 0.07 m2 that turns at 25.0 rad/s in a 0.48 T magnetic field. What is the current through the coil when the normal to the coil makes an angle of 30o with the magnetic field? The resistance in the coil is 7.84 Ohms. Give your answer in Amperes.
True or False A moving charge entering a magnetic field parallel to the field will move in a straight line. A man whose resistance is 10,000 Ω has 120 volt potential difference across his body. This would cause a fatal shock. Adding resistors to a parallel circuit decreases the equivalent resistance. The resistance of a resistor increases with decreased temperature The terminal voltage (V) of a battery is always less than its EMF (ξ). The electric field E is a scalar but the electric potential V is a vector.
