Consider an atom. Which contributes most to the size of the atom?

Which of the following choices describes the difference between work and power? A. Work done is the net force in every equal time interval. Power is the work done in every equal time interval. B. Power is the product of net force and displacement.

The resistance of the body varies from approximately 500 kΩ (when it is very dry) to about 1.00kΩ (when it is wet). The maximum safe current is about 5.00 mA. At 10.0mA or above, muscle contractions can occur that may be fatal.

The left plate of a parallel plate capacitor carries a positive charge Q, and the right plate carries a negative charge - Q. The magnitude of the electric field between the plates is 100 kV/m.

The symbol for speed is v and the symbol for time is t. If v = 13t + 11, then what is t?

If the car's speed decreases at a constant rate from 60 mi/hmi/h to 50 mi/hmi/h in 3.0 ss, what is the magnitude of its acceleration, assuming that it continues to move in a straight line?

What happens to particles when a substance gains energy and changes state?

The density of mercury is 13,600 kg/m³. Determine the mass of 10.0 cm³ of mercury.

A force of 250 N is applied to an object that accelerates at a rate of 10m/sec2. What is the mass of the object?

The grounded conductor and the grounding conductor are one and the same conductor and perform the same function.
