Answer:
The speed of the 1 kg red ball 8.04 m/s .
Explanation:
Given :
Separation between rods , d = 1.5 m .
Mass of the red ball is 1 kg .
Mass of the orange ball is 5.7 kg .
Angular velocity , .
Now , distance of center of mass from red ball is :
We know , speed is given by :
Hence , this is the required solution .
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
