Given:
heat generated by John's cooling system, = 45 W (1)
If ρ, A, and v corresponds to John's cooling system then let be the variables for Mike's system then:
Formula use:
Heat generated,
where,
= density
A = area
v = velocity
Solution:
for Mike's cooling system:
=
⇒ =
× A ×
= 4.513
A
Using eqn (1) in the above eqn, we get:
= 4.513 × 45 = 203.09 W
Answer:
<u>Option-(A): </u>A new moon is quite near the Sun in the sky.
Explanation:
- While the position of the new moon inside our sky has such an orientation that we are not able to see or observe the actual position and shape of the new moon.
- As the path or revolution is much more elliptical then we can imagine, for the moon there are certain position of motion inside the celestial space that for some times it looks for different then the other and such position generates the concept of a new moon.
