The answer for your diving board would be 7.2
The mechanical advantage is defined as the ratio between the load (output force) and the effort (input force):
for the ramp in our problem, the output force is 300 N, while the input force is 100 N, so the mechanical advantage of the ramp is:
Explanation:
work input is the work done by the machine in lifting the drum = Force × distance
100N × 10m
= 1000 J
Answer:
273 Kelvin
Explanation:
If -273 Celsius is 0 Kelvin, then 273 Kelvin will be 0 Celsius.
