#8 positive kinetic energy
Answer:
Explanation:
Given that
a= 8 cm (square)
A= a ² = 64 cm²
d= 4.2 mm
d₁= 2.1 mm ,K₁= 4.7
d₂=2.1 mm , K₂=2.6
We know that capacitance given as
Net capacitance
We know that stored energy given as
V= 76 V
The answer is a. nuclear fission is breaking up
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!!!
Explanation:
a. Average speed = distance / time
= 100 m / 70 s
= 1.43 m/s
b. Average displacement = displacement / time
= 0 m / 70 s
= 0 m/s
Distance is the length of the path traveled. Displacement is the difference between the final position and initial position.
