Answer: Quadrupled
Explanation:
Because when it’s doubled they are going to make another pair so 2+2=4
When an astronaut brings a cube from the Earth to the Moon, the inertial mass remains constant, but the weight decreases.
<h3>What is the difference between mass and weight?</h3>
Mass of the body is defined as the amount of matter a body have. It is denoted by m and its unit is kg.
Weight is defined as the amount of force an object expert on the surface. It is given as the product of mass and the gravitational pull.
When an astronaut brings a cube from the Earth to the Moon, the inertial mass remains constant, but the weight decreases.Because the value of the gravitational acceleration is different on the moon.
Hence, option D is correct.

I would say 2nd law. Go over this with your teacher though
Then the the speed of the molecules also increase

Hello!</h2>
The answer is A. Chemical energy to heat energy to kinetic energy to electrical energy.
<h2>
Why?</h2>
Let's check the energy conversion given in the statement:
Chemical energy: Chemical energy is usually obtained from a natural resource combustion. For this particular case is the result of natural gas combustion.
Heat energy: Heat energy comes from chemical reactions such as natural gas combustions.
Kinetic energy: Kinetic energy is obtained by turbines transforming the pressurized steam on mechanical movement. Turbines are formed by a turbine that absorbs the heat energy to do mechanical work and transmit it to an output rotating shaft.
Electrical energy: Electrical energy is generated by gas turbines when the rotating output shaft is connected to an electrical generator. Electrical generators use mechanical energy to generate electrical energy by using electromagnetic induction. Electrical generators are basically formed by a rotor and a stator.
Have a nice day!
