The answer is D. Electrical energy can be transformed into both heat and light.
A particle confined to move along a curved path has only one degree of freedom. inclined plane are some examples of constrained motion. Every condition of constraint reduces the number of degree of freedom by one.
I hope this helps!
If you increased the speed of rotation of the Earth you would get a perceived decrease in the weight of the object due to an increased centrifugal force.
Increase it fast enough and the momentum of the object will eventually overcome the gravitational pull on it and it will fly off the planet.
I believe it would be 60*3.5. I apologize if this information is wrong.
Answer:
D. Asthenosphere
Explanation:
The asthenosphere is relatively plastic part of the mantle which underlies the brittle lithosphere. In the asthenosphere, it is generally believed that the rocks are in ductile state and easily moves. It is the site of convection within the earth. In mantle convection, hot and light materials rises and keeps moving into upper crustal levels till they solidify. Here also, cold and denser materials sinks deeper till they turn to melt. This differences in temperature and density sets up a convective cell within the mantle. Several convective cells are in the mantle.
