CLO1 C2
b) A steel block with a mass of 30 g and a temperature of 100 °C was put into
container of water. The water temperature is 20 °C . If the temperature of the
mixture is 25°C, calculate the mass of water in the container (unit kg). Given
the specific heat capacity of water is 4200 J/kg°C and steel is 1400 J/kg°C.

Need asap ‼️ 20 pts which gravitational force field diagram is drawn correctly? (answers in pictures below)

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
