Newton’s law of gravity is considered “universal” because it is believed to be applicable to the entire Universe (to a good approximation). Gravity does not just pull an apple from a tree, but also pulls the Moon to the Earth, the Earth to the Sun, and so on. Gravity is a fundamental force of nature.
Answer:
20 meters per second
Explanation:
If an object accelerates for 2 seconds, and accelerates by 10 meters per second, then that objects speed will be 20 meters per second, assuming hat there are no other factors involved.
Choice-'a' is a slippery, misleading, ambiguous statement,
but it's less wrong than any of the other choices on this list.
Answer:
Find the list below.
Explanation:
Energy conversion imply the transformation of energy from one form to another. Examples of these conversions in my home include the following:
1. Chemical energy stored in food is converted to mechanical energy used in working(example sweeping)
2. Chemical energy stored in batteries are used to produce sound energy from the radio.
3. Electrical energy flowing through the wires are used to provide heat energy from the heating device.
4. Electric energy stored in the fan is converted to kinetic energy.
5. Chemical energy stored in petrol is converted to mechanical and electrical energies in the generator.
6. Electric energy supplied by the electric gas cooker is used to generate thermal energy after heating water.
7. Electrical energy flowing through the wires supply light energy in the bulbs.
8. Electric energy is converted to light and sound energy in the televisions.
9. Light energy from the sun is converted to chemical energy in the plants at the garden.
10. Electric energy is converted to sound and light energy in the kitchen blender.
