5. A piece of metal weighing 50 g and specific heat capacity 0.11 calg is heated to 100°C. The metal is dropped to a calorimeter containing 60 g of liquid. The temperature of the calorimeter with its content changes from 23.5°C to 30°C. If the water equivalent of the calorimeter is 10 g, calculate the specific heat capacity of the liquid​

The earth remains in orbit around the sun due to the force of gravity. how does the force of gravity exerted by the sun on the earth compare to the force of gravity exerted by the earth on the sun?

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

If the spring constant k of a pogo stick is 3500 n m and the weight of the person on the pogo stick is 700 n, how much is the spring in the botom of the pogo stick compressed?
