Explanation:
The two postulates of special theory of relativity
Postulate 1: The law of physics are invariant under any of inertial frame of reference.
Postulate 2: The velocity of light is remains same in each ans every frame of reference and independent of relativity.
They are differ from classical mechanics that in classical mechanics there is no change in mass and length in relative velocity but in relativistic mechanics it changes.
These two postulates implements in phenomenon like time dilation , length contraction etc.

The acceleration at the bottom of the loop is 34m/
Explanation:
<u>Given: </u>
Mass=52kg
Force=1750N
To calculate:
The acceleration at the bottom of the loop
<u>Formula:
</u>
Force=Mass x Acceleration
1750=52 x Acceleration
1750/52=Acceleration
Therefore acceleration at the bottom of the loop is 34m/
Roller coasters are mainly based upon acceleration theory they have two types of acceleration one is at the top of the loop and the other is at the bottom of the loop.
Then the net forces and the values are given. In many problems the roller coaster concept is included and it gives another level of clarity to the problems including the net forces
Answer:
Wheelbarrows, fishing rods, shovels, brooms, arms, legs, boat oars, crow bars, and bottle openers are all examples of levers. Levers may be one of the most used simple machine. As with all simple machines like the lever, they are designed to help make work easier to do.
Explanation:
The correct answer for this question is B)Beats
