1. Part A Which of the ball (s) described would have the most kinetic energy? A. 1. A basketball resting on a chair in the gym. B. 2. A baseball was hit by a bat and now flying through the air. c. 3. A bowling ball stationary on the floor. D. 4.

When measuring current, always place the meter in a. series with the circuit. c. the highest DC volts position. b. the highest AC volts position. d. parallel with the circuit.

2. A hanging chair is suspended on a spring from the ceiling. The 5880 N/m spring stretches from 15 cm long to 25 cm long when you sit in the chair a) How hard is the spring pulling to lift you? b) How hard does gravity pull down on you?

When you raise the temperature of air, the molecules move farther apart from each other. This lowers the density of the warm air. What will happen to this warm air? (In an ideal gas, increasing the temperature of the gas also increases its volume.)

N object has a charge of - 2.0 μc. how many electrons must be removed so that the charge becomes + 2.2 μc?

A lorry with a mass of 5000kg accelerates to overtake a caravan on the motorway. Its acceleration is 1.5m/s². What force must the engine be providing? You can ignore the effects of friction and air resistance

Norma kicks a soccer ball with an initial velocity of 10.0 meters per second at an angle of 30.0% if the ball moves though the air for 3.2 seconds what's the horizontal distance traveled by the ball

Suppose s (t) is the position of an object moving along a line at time t is greater than or equal to 0. What is the average velocity between the times t=a and t=b? What is the instantaneous velocity at t=a?

Estimate how long it would take one person to mow a football field using an ordinary home lawn mower. suppose that the mower moves with a 1-km/h speed, has a 0.5-m width, and a field is 360 ft long and 160 ft wide. 1 m = 3.281 ft.

Badri makes the table below to review the factors that affect the electric force between objects. Which change will correct the error in Badri's table?
