4 times 12 is 48 so 12 times
Answer:
1.) 15.24 J
2.) 7.62 W
Step-by-step explanation:
Given that You do a pull-up, lifting yourself by 0.5 in 2 seconds. If your weight is 600 N,
Convert inches into metres
1 inches = 0.0254 metres
Work done = Force × distance
Work done = 600 × 0.0254
Work done = 15.24 J
Power is the rate at which work is done.
That is,
P = WD / time
Power = 15.24 / 2
Power = 7.62 W
Therefore, 15.24 Joule of work done must be done and 7.62 watt of power output must be required to lift the yourself.
2a and 15a. These are like terms due to the fact they have the same variables in this case "a".
Step-by-step explanation:
100-50=50
50/5=10
10/10=1 and
