I'm pretty sure that it's 815.
Well, energy can be produced from the burning of fossil fuels which produce steam to spin turbines which generates electricity. But fossil fuels like coal and oil are no renewable.
Some renewable ways to get energy is water where they separate hydrogen from h2o because hydrogen can be made into energy. Also nuclear fission is another way to get energy. That's when in a nuclear power plant, the atoms nucleus is split which sends a large amount of energy.
Wind energy is another source of energy, which is from windmills. Another renewable energy source is solar energy. That's when u use solar cells, like some houses and calculators have, which generates a lot of energy, but only in the day since the sun doesn't shine in the nigh.
Hope I helped!!!
It should be a metamorphic rock as those rocks are formed due fue to heat and pressure
Answer:
gravitational force
Explanation:
We have four types of fundamental forces in nature
1) Electromagnetic force: It is of either repulsive or attractive type of force and this depends on distance between charges and polarity of charge.
2) Strong and weak nuclear force: this is also of attractive or repulsive type of force and it only depends on distance between two nuclei.
3) Gravitational force: It depends on the mass of the objects and it is only attraction type of force.
so here all matter in universe attract each other only due to gravitational force because all other forces are of both type i.e. attraction and repulsion both.
so correct answer will be
gravitational force
Both physicians Einstein and Newton explained the gravity.
Einstein described the gravity by suggesting that the space-time around any object is bent, while Newton described gravity by principle of action.,
