Who know the answer
bekas [8.4K]

First, let's explain the variables. F means force, m means mass, and a means acceleration. F is measured in Newotns [N], mass is measured in kilograms [kg], and acceleration in measured in meters per squared second [m/s²].

Now let's mover on the first problem.

Given

m = 1000 kg

a = 3 m/s²

According to the second law of Newton, the force is equal to the acceleration multiplied by the mass.

F = am\\F = 3 * 1000\\F = 3000 N

The answer is 3000 N.

The second problem is smiliar.

Given

m = 70 kg

F = 250 N

We use the same formula from before, and use a bit of algebra to adapat it to our needs.

F = ma\\\frac{F}{m} = a\\a = \frac{F}{m}\\a = \frac{250}{70} \\a = 24\frac{1}{7} m/s^{2}

The answer is 24 1/7 s/m^2.

How does a nuclear reactor produce electricity
kaheart [24]

Answer:

Explanation:

Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity. Nuclear power plants use heat produced during nuclear fission to heat water. The heat produced during nuclear fission in the reactor core is used to boil water into steam, which turns the blades of a steam turbine. As the turbine blades turn, they drive generators that make electricity
