Thinking about an analogue clock, calculate the angular displacement in revolutions, radians and degrees for the following: • A
second hand after three minutes An hour hand after 20 minutes The minute hand as it moves from 9.15 to 12.45.
1 answer:
Answer:
1.047 rad
Explanation:
A secondhand makes a complete revolution (360 degrees) in 60 seconds, so it displaces 6 degrees for every second of elapsed time (360/60 = 6).
And in 10 seconds, it will make a displacement of 10 degrees (6 * 10 = 60).
Finally converting the result into Radians by multiplication with π/180.

Answer: 2000 J.
Explanation: Since work is force*displacement, we just have to multiply the force by the distance: w = f*d = 400 N*5.0 m = 2000 J.

Hello!
Use the equation F = m · a (Newton's Second Law) to solve. Substitute in the given values:
F = 5 · 20
F = 100N
