Explanation:
work done =force *distance
work done =17000*26
work done=442,000 joules.
Refer to the figure shown below.
The velocity of the child and the velocity of the ship should be added vectorially to find the speed and direction of the child relative to the water surface.
The magnitude of the child's velocity is
v = √(2² + 18²) = 18.11 mph
The direction of the child's speed is
θ = tan⁻¹ (18/2) = tan⁻¹ 9 = 83.7° north of east or counterclockwise from the eastern direction.
Answer:
The magnitude is 18.1 mph.
The direction is 84° north of east.
Answer:
-In the isothermal process, temperature is kept constant so change in temperature when work is done on the system is zero. The internal energy of the system depends on temperature. So, $\Delta U=0$.
Explanation:
Circular. Look at a clear horizon, you'll see a curve. Go skydiving. Become smart enough, become an astronaut, go into space and look at the shape of earth yourself.
