During the last 50 million years, the lithospheric plates carrying modern day India moved toward its present position. As it moved, the Himalayan Mountains were formed along the boundary of the Indian and the Eurasian plates. Which of the following best explains why the mountains formed at the plate boundary?

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
