Lift your legs up and down and redo that
Answer:
The current would you need flowing through the loop is
Explanation:
The magnetic moment is permanent, the area is equal to:
The current is:
Replacing the area value, the current is:
Answer:
6250 J
Explanation:
Work is the distance times the component of the force along that distance.
The horizontal component of the force is:
25 N × cos(60°) = 12.5 N
So the work done is:
W = (500 m) (12.5 N)
W = 6250 J
The diagram is in the picture attached.
Options are:
A) 32 °C
B) 70 °C
C) 92 °C
D) 100 °C
In order to find the value required, you need to look at the diagram and follow these steps:
1) search for the value of 70 kPa on the y-axis;
2) move on a horizontal line towards the right until you reach the line D;
3) move on a vertical line down, towards the x-axis;
4) read at what value of °C you are at.
Doing so, you can see that you are at a value a little bit above 90 °C (see picture).
Hence, the correct answer is
C) 92°C.
27) Velocity and time
28) it indicates increasing velocity
29) It is moving in constant velocity which means no acceleration.
