The work done on the box by the applied force is zero.
The work done by the force of gravity is 75.95 J
The work done on the box by the normal force is 75.95 J.
<h3>The given parameters:</h3>
- Mass of the box, m = 3.1 kg
- Distance moved by the box, d = 2.5 m
- Coefficient of friction, = 0.35
- Inclination of the force, θ = 30⁰
<h3>What is work - done?</h3>
- Work is said to be done when the applied force moves an object to a certain distance
The work done on the box by the applied force is calculated as;

where;
a is the acceleration of the box
The acceleration of the box is zero since the box moved at a constant speed.

The work done by the force of gravity is calculated as follows;

The work done on the box by the normal force is calculated as follows;

Explanation:
Seismic waves are both transverse and compressional or longitudinal waves.
A seismic wave is an elastic wave that causes a sudden disturbance in earth materials.
- Seismic waves are both longitudinal and transverse waves.
- There are two main types of seismic waves which are the surface and body waves.
- The surface waves runs on the earth surface. These are the rayleigh and love waves.
- The surface waves causes damages on the earth surface as they are both longitudinal and transverse.
- Body waves moves within the earth surface. They are p-waves and s-waves.
- P-waves are longitudinal or compressional waves that propagates within the earth surface.
- S-waves are transverse waves that moves perpendicularly to their direction of propagation.

Answer:
If the boat is going 36 km/h, then it will take about 5.8 hours to travel a distance of 210 km/h.
Explanation:
To calculate time, you have to divide the distance by the speed.
In this case, we take 210 and divide it by 36. The answer you will get is 5.83...
