A100 w electric heater (1 w = 1 j/s) operates for 11 min to heat the gas in a cylinder. at the same time, the gas expands from 1 l to 6 l against a constant external pressure of 3.527 atm. what is the change in internal energy of the gas? (1 l·atm = 0.1013 kj)
a lot of electric so that the battery can work
these small rocky objects orbiting the sun have no atmosphere and are traces from the formation of the solar system. thousands of asteroids can be found revolving around the sun in an “asteroid belt", an area located between the orbits of mars and jupiter.
series resistors just add.
rt = r1 + r2 + r3r1 = 5r2 = 3r4 = 8
rt = 5 + 3 + 8
rt = 16 ohms
since the car is going 10m/s already just put that aside.
accelerating at a rate of 3m/s for 4 seconds
12+10= 22m/s is the final velocity
