Answer:
Stanley Eddington confirmed the theory by his observations and inferences using the solar eclipse
Explanation:
Albert Einstein proposed a theory that energy and mass are interchangeable; termed the theory of special relativity. This can be observed when an object moves with the speed of light. The theory states that all laws in physics are the same for all non-accelerating observers.
Thus,
E = m
This theory could not be proven over many years, therefore it was not fully accepted.
In 1919, Stanley Eddington confirmed the theory by his observations and inferences using solar eclipse. The theory is now very accurate at any given speed when gravitational force tends to zero. This has lead to other observations to prove Einstein's theory.
Answer:
Explanation:
Given
Time taken to reach ground is
Malda initial velocity
Let h be the height of Cliff
using
where, u=initial velocity
t=time
In first case chirpy drop downward thus u=0
For Milada there is horizontal velocity u=95 cm/s=0.95 m/s[/tex]
time taken to reach the ground will be same so distance traveled in this time with 0.95 m/s horizontal velocity is given by
