A student has a mass (including clothes and shoes) of 65.0 kg. She drinks a 12 oz. can of soda, with a nutritional energy content of 140 Cal.

A pendulum is taken to another planet where it swings back and forth exactly 17 times every 35.66 seconds. The pendulum's arm is 0.74 m long. What is the acceleration due to gravity on this planet in units of m/s?

Suppose that a box is accelerating at a rate of 4 m/s2. If the net force is tripled and the mass is doubled, then what is the new acceleration of the box?

Two planes, which are 37403740 miles apart, fly toward each other. their speeds differ by 35mph35â¢mph. if they pass each other in 44 hours, what is the speed of each?

A toy truck has a speed of 3 m/s and kinetic of 36 J what is its mass?

Resistors in parallel together contain less resistance than resistors in series together. Create an analogy to explain this phenomena and post it here.

Unlike the idealized voltmeter, a real voltmeter has a resistance that is not infinitely large. part a a voltmeter with resistance rv is connected across the terminals of a battery of emf e and internal resistance r.

The acceleration of an object is the slope of its velocity-time graph. True False
