Not so fast.
I think you're using 'accelerating' to mean 'speeding up', but you really need
to be more careful with it. "Acceleration" means ANY change in speed OR
direction.
If an object's speed to the left is decreasing, or its speed to the right is
increasing, then the net force on the object must be directed towards
the right.
If an object is moving with constant speed in a circular path, then it's
constantly accelerating, because its direction is constantly changing.
The force on it is always directed towards the center of the circle, so
there's one point on the path where the force is directed straight to the right.

F=ke where f is the force, k is the spring constant, e is the extension....all in standard units
Answer: The correct order of energy transformation is from CHEMICAL ENERGY to ELECTRICAL ENERGY to LIGHT ENERGY
Explanation:
Energy which is simply defined as the ability to perform work is made up of different forms, these include:
- Mechanical energy: Associated with machines at work.
- LIGHT ENERGY: produced by light bulbs
- ELECTRICAL ENERGY: taking in by television set and other electrical appliances.
- CHEMICAL ENERGY: stores in food and other fuels
- Sound energy: Produced by vibrating objects example piano, drums.
According to the law of conservation of energy, energy can neither be created nor destroyed in a closed system, but can be transformed from one form to another, thereby keeping the energy in the closed system constant. From the question, the circuit is an example of a closed system and the order of energy transformation taking place is from the battery (CHEMICAL ENERGY) to ELECTRICAL ENERGY(power source) to LIGHT ENERGY(bulb). I hope this helps, thanks.
Explanation:
Given that,
Speed of particle = 0.720 c
Momentum = 4.350\times10^{-19}\ kgm/s[/tex]
(I). We need to calculate the mass of the particle
Using formula of momentum
We need to calculate the rest mass of particle
Using formula of rest mass
Where, = rest mass
Put the value into the formula
(b). We need to calculate the rest energy of the particle
Using formula of energy
Put the value into the formula
(c). We need to calculate the kinetic energy of the particle
Using formula of kinetic energy
(d). We need to calculate the total energy of the particle
Using formula of energy
Put the value into the formula
Hence, This is the required solution.
Answer:p Pulls down on the object changing inertia creating an affect in momentum
