Answer:
A simple machine consisting of an axle to which a wheel is fastened so that torque applied to the wheel winds a rope or chain onto the axle, yielding a mechanical advantage equal to the ratio of the diameter of the wheel to that of the axle.
1 cubic cm is the same as 1 mL, so the answer would be C.
The answer is C. elastic potential energy
Mass: the amount of matter an object contains
Weight: mass•acceleration due to gravity(9.8m/s) / the force of gravity acting on an object
Answer:
for the people of the Earth traveling they last much more than 70 years
Explanation:
In order to answer this answer we must place ourselves in the context of special relativity, which are the expressions for time and displacement since the speed of light has a finite speed that is the same for all observers.
The life time of the person is 70 years in a fixed reference system in the person this time we will call their own time (t₀), when the person is placed in a ship that moves at high speed, very close to the speed of the light the time or that an observer measures on Earth, the expression for this time is
t = t₀ 1 / √(1 - (v / c)²)
We see that if the speed of the ship is very close to the speed of light the
the value of the root of the denominator is very high, for which for the person on Earth it measures a very large time even when the person on the ship travels has a time within its 70 years of life
In concussion, for the people of the Earth traveling they last much more than 70 years
