A person lost 4800 calories in 30 days. If the calory loss is uniform, calculate the loss of calory per day.

Kamatichi, a fruit vendor sells 30 apples and 50 pomegranates. If she makes a profit of ₹8 per apple and loss ₹5 per pomegranate. What will be her overall profit and loss?

A circular coil of radius 8.0 cm and 20 turns is rotated about its vertical diameter with an angular speed of 50 rad s^(-1) in a uniform horizontal magnetic field of magnitude 3.0xx10^(-2)T . Obtain the maximum and average emf induced in the coil. If the coil forms a closed loop of resistance 10Omega , calculate teh maximum value of current in the coil Calculated the average power loss due to Joule heating. Where does this power come from?

The thickness of a metallic plate is 0.4 cm. The temperature between its two surfaces is 20° C. The quantity of heat flowing per second is 50 calories from 5cm^2 area. In CGS system, the coefficient of thermal conductivity will be

A metal ball of mass 1kg is heated by means of a 20W heater in a room at 20^(@)C . The temperature of the ball becomes steady at 50^(@)C . (a) Find the rate of loss of heat to the surrounding when the ball is at 50^(@)C . (b) Assuming Newton's law of cooling, calculate the rate of loss of heat to the surrounding when the ball is at 30^(@)C . (c) Assume that the temperature of the ball rises uniformly from 20^(@)C to 30^(@)C in 5 minutes. Find the total loss of heat to the surrounding during this period. (d) Calculate the specific heat capacity of the metal.

A circular coil of radius 8.0cm and 20 turns rotated about its vertical diameter with an angular speed of 50"rads"^(-1) uniform horizontal magnetic field of magnitude 3xx10^(-2)T. Obtain the maximum and average emf induced in the coil if the coil froms a closed loop of resistance 10Omega then calculate the average power loss due to joule heating.

A gas expands 0.5 L against a constant pressure at 1 atm. Calculate the work done in joule and calorie.

A refrigerator works between 4^@C and 30^@ , it is required to remove 600 calories of heat every second in order to keep the temperature of the refrigetor space constant. The power required is :(Take1 cal = 4.2 joules).
