Answer:
The water vapor contains a lot of stored, "latent heat", energy (sunlight energy that was added during evaporation). The stored energy is released when the water vapor condenses and turns back into water.
Explanation:
Answer:
Vp = velocity of plane
Vpx = Vp cos 55 = 8 * .57 = 4.59 m/s velocity of plane along x-axis
Vpy = Vp sin 55 = 8 * .82 = 6.55 m/s velocity of plane along y-axis
If Wx = -3 m/s then
Vx = 4.59 - 3 = 1.59 m/s
Vy = 6.55 m/s wind does not affect vertical speed
tan theta = Vy / Vx = 6.55 / 1,59 = 4.12
theta = 76.4 deg above x-axis
V = (1.59^2 + 6.55^2)^1/2 = 6.74 m/s
Answer: The law of conservation of energy can be seen in these everyday examples of energy transference: Water can produce electricity. Water falls from the sky, converting potential energy to kinetic energy. This energy is then used to rotate the turbine of a generator to produce electricity.
Explanation: Thats what we learned
Answer:
311,850 N
Explanation:
We can solve the problem by using Newton's second law:
where
F is the net force applied on an object
m is the mass of the object
a is its acceleration
For the object in this problem,
m = 27 kg
Substituting, we find the force required:
