Answer:
stratosphere
Explanation:
the stratosphere is the second major layer of the atmosphere just above the troposphere, it has its lower area to be cooler and higher area to be warmer due to the ozone layers absorption of ultraviolet rays. It is also the layers which planes fly through because it is stable.
Answer:
the energy food has is transformed into mechanical energy during exercise,
Explanation:
When a person is exercising, the energy accumulated in food is transformed into mechanical energy, in general if he is running in kinetic energy and if he is rising and falling in potential energy.
In this case the energy food has is transformed into mechanical energy during exercise,
Answer:
3.974 Joule
Explanation:
Diameter of ring = 7.7 cm
a = Distance from the center = d/2 = 3.85 cm = 0.0385 m
Q = Charge = 5 mC
q = Charge to move = 3.4 mC
k = Coulomb constant = 9×10⁹ Nm²/C²
Work done will be equal to Potential energy when mass is at center
∴ Work to move a tiny 3.4 mC charge from very far away to the center of the ring is 3.974 Joule
Answer:
brooo it is rotation .............
B. The Earth radiates an amount of energy into space equal to the amount it receives.
Part of the solar energy is reflected by the Earth into space, this is known as albedo. The other part of the energy radiated by the Earth in the form of infrared radiation, is absorbed by the greenhouse gases, which cause most of this infrared radiation to be emitted into space. Therefore, the net flow of energy is zero.
