Answer:
55 min
Explanation:
The missing question is: how long does the trip take?
First of all, we need to find the initial distance covered by Dylan. In the first part, he rides for
at a speed of
v = 15 mph
therefore, the distance he covered is
Then Dylan stopped for a time of
Finally, on the way back, Dylan covered again this distance but travelling at a new speed of
v = 10 mph
So, the time he took is
So, the total time of the trip was
Einstein's energy mass equivalence relation say that if the whole given mass is converted to energy then it would be
where
m = mass in kg
c = speed of light in m/s
this is the origination of quantum physics and by this formula we can relate the dual nature of light and particle
So correct relation above will be
Answer:
Explanation:
