Given what we know, we can confirm that the tensional force of a system can in theory be changed without diminishing its force through the use of an ideal pulley.
<h3>What is an ideal pulley?</h3>
- A pulley is a small wheel through which a string or chain is run.
- These are used in order to change the direction of a force.
- An ideal pulley would be one in which there is no friction and the pulley itself would have no mass.
- Therefore, the force would be able to change directions without giving part of its force to the pulley system.
Therefore, we can confirm that the only known way to change the direction of a force without diminishing its value would be through the use of a frictionless and massless pulley system otherwise known as an ideal pulley.

Answer:
The water would weigh 25.04 pounds.
Explanation:
Mass = volume × density
Given;
Volume of water = 3 gallons of water
Density of water = 1000kg/m^3
Converting the density to pounds per gallon.
Density = 1000kg/m^3 × 2.205pounds/kg × 1/264.172gallon/m^3
Density = 8.347 pounds/gallon
Therefore, the mass can be calculated as;
Mass = 3 gallons × 8.347pounds/gallon
Mass = 25.04 pounds
Therefore, the water would weigh 25.04 pounds.
Nothing happens to the mirror.
However, if the ray is within some suitable range of
wavelengths, the ray is reflected from the mirror's surface.
