Answer:
A book containing information on various types of science related topics.
Answer:
<h2>Total thermal energy for all air molecules is 59.54 J</h2>
Explanation:
As we know that the ball comes to rest finally so here we can say that
initial total potential energy of the ball is transferred to the air molecules
So here we have


So here we have

So all the gravitational potential energy of the ball will convert into thermal energy of air molecules which is equal to 59.54 J
Answer:
T=189.15 N
Explanation:
As we know that for downward motion
F acting = F (weight) - Tension T
m a = mg - T
⇒ T = m (g - a)
T = 29.1 kg ( 9.8 m/s² - 3.3 m/s²)
T=189.15 N
The given question is incomplete. The complete question is attached with an image below.
Explanation:
Mass flow rate through region A will be calculated as follows.
Rate = 
= 
= 
= 
Therefore, we can conclude that the mass flow rate through region A is
.
