The world’s largest jelly, which had a mass of about 4.00 × 104 kg, was made in Australia in 1981.
a. How much energy must be transferred by heat from the jelly in order for its temperature to decrease 20.0°C? Assume that the specific heat capacity of the jelly equals that of water.
b. Suppose all this energy is transferred by heat to a sample of gas. At the same time, the gas does 1.64 × 109J of work on its surroundings. What is the net change in the internal energy of the gas?

Ball b is hanging from an inextensible cord. an identical ball a is released from rest when it is just touching the cord and drops through the vertical distance h a 5 8 in. before striking ball b. assuming e 5 0.9 and no friction, determine the resulting maximum vertical displacement h b of the ball b

Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

Atank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. the values in the table show the volume v of water remaining in the tank (in gallons) after t minutes. t(min) 5 10 15 20 25 30v(gal) 694 444 250 111 28 0(a) if p is the point (15, 250) on the graph of v, find the slopes of the secant lines pq when q is the point on the graph with t = 5, 10, 20, 25, and 30.(b) estimate the slope of the tangent line at p by averaging the slopes of two secant lines.(c) use a graph of the function to estimate the slope of the tangent line at p. (this slope represents the rate at which the water is flowing from the tank after 15 minutes.)show all steps.
