2a for example the first one,2sec. You know that every second it moves 3metres further. So 2x3=6 but you start at 0.50m so 6+0.50=6.5
Answer:
Explanation:
Expression for relative velocity
=
= (.54 + .82 )c/
= 1.36 c / 1.4428
= .94 c
β = .94
Hi there!
Assuming you're asking about the solar system, there are nine planets. But, if you're wanting to know about the universe, there are trillions and trillions of planets (most of which we haven't yet discovered).
Hope this helps!
Answer:
The minimum work per unit heat transfer will be 0.15.
Explanation:
We know the for a heat pump the coefficient of performance () is given by
where, is the magnitude of heat transfer between cyclic device and high-temperature medium at temperature and is the required input and is given by , being magnitude of heat transfer between cyclic device and low-temperature . Therefore, from above equation we can write,
Given, and . So, the minimum work per unit heat transfer is given by
