Mechanical waves are those waves that require a material medium for propagation.
<h3>What are mechanical waves?</h3>
Generally, we define a wave as a disturbance along a medium which transfers energy. It then follows that waves move energy from one point to another.
Waves can be classified as;
- Mechanical waves
- Electromagnetic waves
Mechanical waves are those waves that require a material medium for propagation such as sound, and waves on a strings.

9.4 × 10⁻¹⁹ J. (2 sig. fig).
<h3>Explanation</h3>
The kinetic energy of an object depends on its mass and its speed. Mass is given for this neutron. However, the speed of the neutron needs to be found.
What's the speed of this neutron?
(3 sig. fig. Speed is an intermediate quantity. Include at least one more sig. fig. for the value of kinetic energy to be accurate to 2 sig. fig.)
What's the kinetic energy of this neutron?
,
where
- is the mass of the object, and
- is the speed of the object.
.
(2 sig. fig as in mass, distance travelled, and time).
Answer:
8.2 m/s
Explanation:
The horizontal component of the velocity is given by:
where
v = 10 m/s is the magnitude of the velocity
is the angle at which the ball has been thrown, with respect to the horizontal
Substituting the values into the equation, we get
Answer:22N
Explanation:
Net force = F1 + F2
=12+10=22N
Both forces are applied in the same direction. So the net force 22N causes a change in the body's state of rest. When several forces act in a body, the body will move in the direction of the net force.
