The correct matches are as follows:
<span>1. Mechanical Energy
</span>This is the energy of motion and position - Kinetic Energy and Potential Energy are included here.
<span>
2. Electrical Energy
</span>This is the type of energy that is given off as a result of electrons (charges!) moving through a conductor.
<span>
3. Light Energy
</span>This is the only form of energy we can see with our eyes!
<span>
4. Thermal Energy
</span>This is heat energy! It can be transferred through conduction, convection, or radiation.
<span>
5. Sound Energy
</span>This is energy that is transmitted through vibrations.
<span>
6. Kinetic Energy
</span>This is the energy that all moving objects have. <span>
7. Potential Energy
</span>This is stored energy, waiting to be used!
There are loads of similarities, but there are differences and that's what you want!
Speed- Is usually referring to how fast an object moves, it is calculated by space per unit.
Velocity- Refers to the rate at which said object changes position in a certain direction. Usually calculated by the displacement of space per unit.
SO it sounds the same, but simple answer Velocity deals with direction, and speed does not!
Thus, the car would travel a distance of 50 metres in 4 seconds.
Answer:
a
When
b
When
Explanation:
From the question we are told that
The radius is R
The current is I
The distance from the center
Ampere's law is mathematically represented as
When
=>
But when
Answer:
2.210N
Explanation:
Workdone = Force x distance
Distance = 38m , Workdone = 84J
Hence 84J = Force x 38m
Force = 84J / 38m
Force = 2.210N =2.2N
