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
Based on this scatter plot, I can say that in general, test scores vary directly with study time. In other words, in a population large enough to reveal the direct relationship, the more time a student spends studying, the higher that student's test scores will be.
I didn't need a scatter plot to reveal that to me. That's practically in the category of Law given to Moses at Sinai.
The average velocity is 12.5 meters per second
Im not sure about controlled parameters, but i can explain how variables work. There are different types of variables. An independent one is the thing you change every time you do the experiment. Dependent variables are what you keep the same every time you do the experiment. (i hope this somewhat helped)
Answer:
To calculate the energy in joules, simply enter the mass of ammunition (in grams) that you use, and the fps that you've read from your Chrono unit.
