The resistance of a circuit is a measure of the energy
that a current loses while flowing through the circuit.
Ease or difficulty is not a helpful concept in the case of
an electrical circuit.
Answer:
Approximately
upwards (assuming that
.)
Explanation:
External forces on this astronaut:
- Weight (gravitational attraction) from the earth (downwards,) and
- Normal force from the floor (upwards.)
Let
denote the magnitude of the normal force on this astronaut from the floor. Since the direction of the normal force is opposite to the direction of the gravitational attraction, the magnitude of the net force on this astronaut would be:
.
Let
denote the mass of this astronaut. The magnitude of the gravitational attraction on this astronaut would be
.
Let
denote the acceleration of this astronaut. The magnitude of the net force on this astronaut would be
.
Rearrange
to obtain an expression for the magnitude of the normal force on this astronaut:
.

The proportion of the total energy input that is put to use in a solar cell is known as its efficiency, so this is a true statement.
<h3>What is a Solar cell?</h3>
A solar cell, also known as a photovoltaic cell, is a type of electronic device that uses the photovoltaic effect to convert light energy directly into electricity.
<h3>What is Energy?</h3>
Energy is the ability to perform work. It could exist in several different forms, such as potential, kinetic, thermal, electrical, chemical, radioactive, etc. Additionally, there is heat and work, that is energy being transferred from one body to another. It is always assigned based on its nature once it has been transmitted. Thus, heat transmitted may manifest as thermal energy while work performed may result in mechanical energy.
Hence, the proportion of the total energy input that is put to use in a solar cell is known as its efficiency, so this is a true statement.
