The specific heat of a certain metal can be determined by measuring the temperature change that occurs when a piece of the metal is heated and then placed in an insulated container that is made of the same material and contains water. Suppose the piece of metal has a mass of 118 g and is initially at 100°C. The container has a mass of 160 g and contains 599 g of water at an initial temperature of 20.0°C. The final temperature is 21.4°C. What is the specific heat of the metal?
kJ/kg·K
At this point, he throws a forward pass 45.0 yards straight downfield perpendicular to the line of scrimmage. Illustrate what is the magnitude of the football's resultant displacement?
An 8.30 kg stone at rest on a spring. The spring is compressed 11 cm by the stone. The stone is after that pushed down an additional 26.00 cm and free. To what highest height (in cm) does the stone rise from that position.
A satellite in a circular orbit around the earth with a radius 1.019 times the mean radius of the earth is hit by an incoming meteorite. Calculate the amount of that work converted to heat

A bowling ball (mass= 7.2 kg, radius= 0.14m) and a billiard ball (mass= .44 kg, radius= .028m) may each be treated as uniform spheres. find the magnitude of the maximum gravitational force
In Millikan's experiment, an oil drop of radius 1.85 μm and density 0.852 g/cm3 is suspended in chamber C whilst a downward electric field of 0.62 × 10^5 N/C is applied. Find the charge on the drop, in terms of e.
How much time is neccesary to stop the crate. A block with mass m = 5.5 kg slides down an inclined plane of slope angle 10.9 ° with a constant velocity. It is then projected up the same plane with the initial speed 3.85 m/s. How far up the incline ..
