The internal pressure increases as the gas is heated
A futuristic design for a car is to have a large solid disk-shaped flywheel within the car storing kinetic energy. The uniform flywheel has mass 370 kg with a radius of 0.500 m and can rotate up to 320 rev/s. Assuming all of this stored kinetic energy could be transferred to the linear velocity of the 3500-kg car, find the maximum attainable speed of the car.
Answer
given,
Echo time = t = 1000 s
speed = ?

a) speed of electromagnetic wave

wave travels Venus two time



d = 1.5 x 10¹¹ m
b) now, echo time



t = 5 x 10⁻⁷ s
