Answer:

Explanation: The two main types of nuclear power are nuclear fusion and fission. Nuclear fission is used in nuclear power plants to create elements. Nuclear fission works by having a stray neutron collide with a nucleus. When this happens, it breaks the nucleus up, and another nuclei collides with another nucleus. A chain reaction occurs as this process continues. I personally think this type of nuclear power is dangerous because the result is radioactive byproducts. Also, meltdowns can occur in a nuclear power plant as a result of nuclear fission. I think nuclear fusion would be a much safer energy source. It is cheap and practically unlimited. Nuclear fusion occurs when two nuclei fuse together to create a larger nucleus. Nuclear fusion also proves Albert Einstein's equation E=mc2. The element you start out with is greater than the element you end up with after fusion occurs. This is due to some of the matter actually being converted into energy, which agrees with Einstein's equation. I think nuclear fusion is a safer energy source because it does not create radioactive byproducts that can be potentially harmful. Nuclear fusion, however, is not understood that well by scientists. As a result, we continue to use nuclear fission because we know how to use it. Until scientists fully understand nuclear fusion, scientists will continue to use nuclear fission for energy sources.

Helpp pls
Kipish [7]

Answer:

The intensity of the electric field is

|E|=10654.37 \:N/C

Explanation:

The electric field equation is given by:

|E|=k\frac{q}{d^{2}}

Where:

  • k is the Coulomb constant
  • q is the charge at 0.4100 m from the balloon
  • d is the distance from the charge to the balloon

As we need to find the electric field at the location of the balloon, we just need the charge equal to 1.99*10⁻⁷ C.

Then, let's use the equation written above.

|E|=(9*10^{9})\frac{1.99*10^{-7}}{0.41^{2}}

|E|=10654.37 \:N/C

I hope it helps you!

Newton’s 3rd law of motion states that “every action has an equal and opposite reaction.” A golf ball was hit with a force of 20
DedPeter [7]

Answer:

<u>Example of Newton's III law</u>

  • In the, golf the ball was hit by a club with certain force. As the club hits the ball it's the action. When the ball flies away its the reaction.
  • When a person swings a golf club at the ball, when it hits the ball, it causes the ball to roll up the face of the club and into the air towards the target.
