Can you please tell what "it" is?
Answer:
Explanation:
Pressure is defined as the thrust acting per unit area.
the pressure by a person wearing loafers is less than the pressure by a woman wearing high heels.
It is because the area of loafers is much more than the area of heels.
Thus, the woman hurts a lot than man.
Answer:
20m/s
Explanation:
Given parameters:
Distance of throw = 50m
Time = 3s
Unknown:
Average speed = ?
Solution:
Average speed is distance divided by time;
Average speed =
Insert the parameters and solve;
Average speed = = 16.66667m/s = 20m/s
The electric flow is defined as the change of the charge in relation to the constant of the vacuum permittivity constant.
That is to say that mathematically this expression could be given as
Here,
= Electric Flux
q = Charge
= Vacuum Permittivity
Replacing with our values and solving to find q, we have,
Therefore the charge is enclose within the octahedron with a charge of
We can base this on the equation of thermal expansion.
ΔL = L₀αΔT
where
ΔL is the expansion of length upon heating
L₀ is the initial length
α is the coefficient of linear expansion
ΔT is the temperature difference
So, if α for Aluminum is greater than α for Copper, then after heating, aluminum would be longer than copper.
