Answer:
Explanation:
Temperature is the degree of hotness or coldness of a body.
Energy is the ability to do work by a body. They are of two forms, potential and kinetic energy. Potential energy is due to the position of a body whereas kinetic energy is due to the motion of a body.
Motion is the change in position of a body with time.
Temperature, energy and motion are all related.
Thermal energy is a form of kinetic energy which is concerned about the motion particles. This form of energy results from heat changes in a body which causes temperature differences.
When a body is heat and changes temperature, the particles begins to vibrate as they gain, thermal energy, a form of kinetic energy. At a point, the particles will break lose and set in motion.
Answer:
v = 12.12 m/s
Explanation:
Given that,
Radius of the curvature, r = 30 m
To find,
The car's speed at the bottom of the dip.
Solution,
Let mg is the true weight of the passenger. When it is moving in the circular path, the centripetal force act on it. It is given by :
The normal reaction of the passenger is given by :
N = 1.5 mg
Let v is the car's speed at the bottom of the dip. It can be calculated as:
v = 12.12 m/s
So, the speed of the car at the bottom of the dip is 12.12 m/s. Hence, this is the required solution.
The interaction that does not take place due to field forces is the interaction between a pen and paper while you write.
<h3>What is the gravity law?</h3>
Gravity law is a well-established scientific theory that states objects can attract each other according to their masses.
This theory (gravity law) was developed by Sir Isaac Newton to explain the movement of objects.
In conclusion, the interaction that does not take place due to field forces is the interaction between a pen and paper while you write.
