1. How many calories of heat are required to raise the temperature of 550 g of water from 12.0°C to

18.0°C? (remember the specific heat of water is 1.00 cal/g x °C)

If a force of 12 n is applied to an object with a mass of 2kg the object will accelerate at

When cars are equipped with flexible bumpers, they will bounce off each other during low-speed collisions, thus causing less damage. In one such accident, a 1750kg car traveling to the right at 1.

A 2.1 times 103 - kg car starts from rest at the top of a 5.0 - m - long driveway that is inclined at 20 deg with the horizontal. If an average friction force of 4.

You are running a 1m/s and increase your velocity to 2.5m/s in 5s. what is your acceleration?

Find the GCF 12, 18, and 84

True or False: If your gas pedal jams, you should turn the key to lock to lock the steering wheel.

Pylon cables in the National Grid have some resistance. Power (watts) = Current2 (amperes) x Resistance (ohms) Looking at the power equation above, can you explain why transmitting electricity at a very high voltage is beneficial?

A bicycle racer sprints near the end of a race to clinch a victory. The racer has an initial velocity of 12.1 m/s and accelerates at the rate of 0.350 m/s2 for 6.07 s. What is his final velocity?

The current in a wire increases from 5 A to 10 A, what happens to its magnetic field? The field is twice as strong the distance of a charged particle from a wire changes from 10 cm to 20 cm, what happens to its magnetic field?

At a constant pressure and a temperature of 280 K, the gas in a cylinder has a volume of 10.0 liters. If the volume of the gas is increased to 20.0 liters, what is the new temperature? 2800 K 28 K 140 K 560 K
