The force the escaping gas exerts of the rocket is 10.42 N.
<h3>
Force escaping gas exerts</h3>
The force the escaping gas exerts of the rocket is calculated as follows;
F = m(v - u)/t
where;
- m is mass of the rocket
- v is the final velocity of the rocket
- u is the initial velocity of the rocket
- t is time of motion
F = (0.25)(40 - 15)/0.6
F = 10.42 N
Thus, the force the escaping gas exerts of the rocket is 10.42 N.

The answer is weak.
The interaction of nature that will depend on the distance through the
way it acts and involved in beta decay is the weak interaction or the weak
force. This interaction is the responsible for radioactive decay which also
plays a significant role in nuclear fission.
The tactile system is actually made up of two distinct skin senses;
protective and the discriminative system. The function of the protective system
is to alert us to harmful stimuli. The receptors of the system are the hairs of
our skin, head and genitals. The discriminative system is to show us what we
are touching, where on our bodies is touching us and what are touching us. The receptors
for his system are the hands, fingers, soles of feet and mouth and tongue.
The required value of the index of refraction of glass is 1.5.
Given data:
The speed of light in a vacuum is, 
.
The speed of light in a glass is, 
.
Light has the tendency to travel from one medium to another, then the difference between the speeds of light in various mediums is determined by a term, known as the index of refraction. The mathematical expression for the index of refraction of glass is,
n = c / v
Solving as
Thus, we can conclude that the required value of the index of refraction of glass is 1.5.
