Can you help me in 1 question. A mad physicist performs two
A mad physicist performs two experiments at the same time. She sits in a small boat floating in a circular water tank with a diameter of 2.4 m and a depth of 1.42 m (without the boat in the tank). The water has a temperature of 20.0 ° C. With her in the boat she has a large iron weight with a mass of 79 kg which she has warmed to 1380 ° C. She gently releases the weight overboard (she is very strong and has good protective equipment despite being crazy ) and waits for the water and the weight has reached the same temperature.(a) What temperature does the water and weight eventually get? You can ignore heat losses to the surroundings (including the boat).(b) How much does the water level rise or fall in the tank when she releases the weight overboard? It's the change I want, not the depth. This is the question can you help me please … read more
