Answer:
The pressure exerted by the woman on the floor is 1.9061 x 10⁷ N/m²
Explanation:
Given;
mass of the woman, m = 55 kg
diameter of the circular heel, d = 6.0 mm
radius of the heel, r = 3.0 mm = 0.003 m
Cross-sectional area of the heel is given by;
A = πr²
A = π(0.003)²
A = 2.8278 x 10⁻⁵ m²
The weight of the woman is given by;
W = mg
W = 55 x 9.8
W = 539 N
The pressure exerted by the woman on the floor is given by;
P = F / A
P = W / A
P = 539 / (2.8278 x 10⁻⁵ )
P = 1.9061 x 10⁷ N/m²
Therefore, the pressure exerted by the woman on the floor is 1.9061 x 10⁷ N/m²
Answer:
Explanation:
Torque created by force 3.34N
= 3.34 x 1.39 = 4.64 N.m
This torque is acting in clockwise direction .
Torque created by force 8.52 N
8.52 x .48
= 4.09 N.m
The force of 8.52 N is acting downward . It may turn the cylinder in clockwise or anticlockwise direction . So we shall consider both the possibilities.
If it rotates the cylinder in clockwise direction
Total torque = 4.64 + 4.09
= 8.73 Nm
If it rotates the cylinder in anticlockwise direction
Total torque = 4.64 - 4.09
= .55 Nm
Net torque will be in clockwise direction.
Distance is the physical length travelled. While the displacement is the shorter distance between any two given points.
<h3>What is distance?</h3>
Distance is a numerical representation of the distance between two objects or locations.
Distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
Displacement is defined as the shortest distance between the two points.
Sam determines the distance by doing the calculation as;
distance = speed × time
Hence, the Sam determines the distance and displacement by the respective formulas.

The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure.
Subtract the total mass of the tank and water by the mass of the empty tank. That will yield the mass of the water.
51.8 - 3.64 = 48.16.
Your answer is 48.16 kg
