To solve this problem it is necessary to apply the equations related to the Force of Friction and Energy.
By definition the friction force is defined as
Where,
Frictional Constant
N = Normal Force -> mg
At the same time we have the definition of the Energy, which can be
E = F*v
Where,
Force
v = Velocity.
Then replacing with our values we have that,
F = 0.5 *34
F = 17
The energy then would be,
E = f v
E = 17 * 0.30 = 5.1 W
Therefore the rate at which heat is generated is 5.1W
The jet stream winds blow storms from west to east
The term is Social facilitation.
Social facilitation can be defined as an improvement in performance caused by the mere presence of others, it can be further distinguished into two types:
- co-action effects which is a phenomenon where increased task performance is caused by the mere presence of others doing the same task.
- audience effect where performance is increased in the presence of a passive spectator/audience
Answer:
Explanation:
Let the total force be F
The force that produces motion in the x direction is given as, 
Let the frictional force be given as:
Thus, the net force is given as:
