Answer:
The maximum depth of water in the tank shall be 22.784 centimeters.
Explanation:
The maximum height will be reached when the rate at which water enters the tank will be equal to the rate at which water will leave the vessel.
Let us assume that the maximum level of water in the tank is 'h' meters
Since the hole is at bottom
According to Torricelli's Law the speed at which the water shall leave the tank equals
Thus the rate at which water leaves the tank will be equal to
Thus equating the rate of inlet of water and rate of outlet of water we get:
The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.
Explanation:
Substances become neutral at the number 7 because at this point, the acid and Base are equal and becomes neutralized
Water freezes at 0 and boils at 100 Celsius. That's my best answer
The universal formula for gravitational force (i.e. Weight) is
W = GMm/(r^2)
Where G is the gravitational constant 6.67*10^-11
M is the larger mass (in this case, the earth)
m is the smaller mass (the astronaut)
And r is the distance between the centers of mass of the objects.
In this case, you start from the given at the surface of the Earth:
800N=GMm/(6.378*10^6m)^2
*Since GMm will remain the same throughout, you don't actually need to solve any of them individually. Just solve for GMm as a single constant.*
After solving for GMm, plug that into the force at the new distance, which is the radius of the earth + height above the surface. Notice that the height above the surface given is the same as the radius of the earth.
W = GMm/(6.378*10^6*2)^2
Solving, you get W = 200 N
