Answer:
Explanation:
What a lot of words to solve such a simple problem! The perpendicular force is the one that is pushing straight down on the plane. There is no side to side movement here or friction acting on this dimension at all. Perpendicular force is the same as the weight of the block. That's it! Perpendicular force is also normal force which is the same thing as weight:
w = mg so
w = (4.04)(9.8) and
w = 4.0 × 10¹ N
Answer:
100 Nm and 25Nm/s.
Explanation:
<u>Given the following data;</u>
Force = 25N
Distance = 4m
Time = 5secs
To find the workdone;
Workdone = force * distance
Substituting into the equation, we have;
Workdone = 25*4
Workdone = 100 Nm
To find the power consumed;
Power = workdone/time
Substituting into the equation, we have;
Power = 100/4
Power = 25Nm/s
The work done on the box is 100 Nm, and the power is 25 Nm/s.
Answer:
d. Critical transportation; situation assessment; and mass care services
Explanation:
The correct answer is option d which is Critical transportation: Situation assessment and mass care services are core capabilities for response.
As we know that critical transportation are very important factor which control capability for responses. Due to fast transportation a life can be saved, people can be out of danger in the situation of natural calamity.
P = U × I
I = P / U = 1600W / 120V = 13.4A
P = 240V × 13.4A = 3216W
If your hair blower isnt rated for 220- 230V(this is the voltage in EU) you are most likely going to burn it.
