First, let's find the total force exerted by the man on the stool.
F = mg
F = (75 kg)(9.81 m/s²)
F = 735.75 N
Next, we must know the maximum load the stool can take. Suppose, the it can take up to 700 N. Since each leg of the stool takes an equal amount of force, this is uniformly distributed. So, the solution is as follows:
Percentage = [(735.75- 700)/700]*100 =<em> 5.1%</em>
Energy is in Joules ( J )
specific heat capacity is in ( Joules per Kilogram per degree Celsius) ( J/kg C )
Answer:
The swimmer has a distance traveled of 800 meters.
The final displacement of the swimmer is 0 meters.
Explanation:
A lap is a round trip made by a swimmer in the pool, so that the distance traveled by swimmer is sixteen times the length of the swimming pool. That is:
A swimmer has a distance traveled of 800 meters.
The displacement is the distance between swimmer and a reference point, let suppose that reference point is located at the beginning of the first lap. Hence, the final displacement of the swimmer is 0 meters.
Answer:
an absorber of x-ray
Explanation:
To make x-ray detection/vision work, you will need at least two items: a source of x-ray and absorbed or x-ray.
The object you want to see itself doesn't have to be the source, but it has to absorb some of the rays instead. When doing a chest x-ray test, the medical employee will put your chest between absorber and source. The heart can absorb some of the rays so it will appear more white than lungs who made of air and won't absorb the rays.
