Answer:
183333 Pa
Explanation:
The weight of the football player is : 550 N ,thus the force the player exerts on the floor is 550 N
The area of blades in contact with the floor is = 30cm² = 0.003 m²
Pressure = Force / Area
Pressure = 550 / 0.003
Pressure = 183333 Pa
Well, first of all, EVERY physical quantity is measured in a combination
of 2 or more units, except for mass, length, time, and electric charge.
ALL other units are made out of these. So it should not surprise you.
[ Example: Speed = (length) / (time) ]
Density is not the mass of a substance. It's the mass of a substance in
a standard volume of it. So the density is made of the mass in any lump
and the volume of that lump. That way, no matter how much of a substance
you have, you can always compare the lump you have to all other substances.
Answer:
20%
Explanation:
Relative Humidity (%) = (water vapor content÷water vapor capacity) × 100
=(7÷35)×100
=(0.2)×100
=20%
According to the Temperature-Water Vapor Capacity Table, the water capacity at 35 °C is 35 grams.
Water Vapor Capacity: The amount of water (grams) which air can hold at a given temperature.
Water Vapor Content: The amount of water vapor actually present in the air.
