From the calculation, the force constant is 192 N. Also, friction would decrease the extension.

<h3>What is the force constant?</h3>

We know that the force constant can be obtained by the use of the relation;

F = Ke

F = applied force

K = force constant

e = extension

We know from Hooks law that the force applied is directly proportional to the extension.

We can write;

F = mgcosθ

F = 43 Kg * 9.8 m/s^2 * sin31°

F = 217 N

K = 217 N/1.13 m

K = 192 N/m

If there is friction between the incline and the crate, it will stretch less because some work will be lost due to friction causing only some fraction of the elastic potential energy to be converted to kinetic energy.

An engine has an energy input of 125 J, and 35 J of that energy is transformed into useful energy. What is the efficiency of the
xeze [42]

The efficiency of the engine at the given useful energy and input energy is 28%.

The given parameters:

  • <em>Input energy of the engine, = 125 J</em>
  • <em>Useful energy of the engine, 35 J</em>

The efficiency of the engine is defined as the ratio of the output energy (useful energy) to the input energy and it is calculated as follows;

efficiency\ = \frac{0ut put \ energy}{1nput \ energy} \times \ 100\%\\\\efficiency\ = \frac{35}{125} \times 100\%\\\\efficiency\ = 28 \ \%

Thus, the efficiency of the engine at the given useful energy and input energy is 28%.
