the cross section area of a hole is 725cm^2. Given that the area of a circle is A=3.14r^2 , find the radius of the hole.
asambeis [7]
The\ area\ of\ a\ circle\ =  \pi r^2 \\ 725\ cm^2 =  3.14r^2 \\
230.57 cm^2 = r^2 \\ \sqrt{230.57\ cm^2} = r \\ \boxed{r = 15.18\  cm}

Approximately how many kilograms (kg) of carnivore (secondary consumer) biomass can be supported by an area of a field containin
Anastasy [175]

Only 10 Kg of secondary consumers can be supported by the ecosystem.

There exists such a thing as the 10% rule in the transfer of energy in biomass from one trophic level to another. This rule ultimately controls the mass of biomass that is available at the next higher trophic level.

This rule state that only 10% of the energy in biomass is transferred to the next trophic level. By this rule, only 10% of the energy in the plant material is transferred to the carnivore population. Therefore, only 10 Kg of secondary consumers can be supported by the ecosystem.

The height of the empire state building is 318 m if a stone is dropped from the top of the building what is the stones velocity
lutik1710 [3]

79 m/s. A stone dropped from the top of the Empire State Building will have a velocity of 79 m/s just before it strikes the ground.

This problem is about free fall, to find the velocity of the stone before it strikes the ground we have to use the equation v_{f}^{2}=v_{0}^{2}+2gh, the initial velocity  of the stone is 0 m/s. Then:

v_{f}^{2}=2gh

v_{f}=\sqrt{ 2gh}

Solving the equation above with g = 9.8 m/s², and h = 318.0 m:

v_{f}=\sqrt{ 2(9.8m/s^{2})(318.0m)}= 78.95 m/s

v_{f}≅ 79 m/s

Andrei [34K]

Answer:

Obviously Our Yellow Star: The Sun....

Explanation:

With a staggering mass of 1.989 × 10^30 kg as well as a gravitation pull of about 274 ms^-1. I think, no other object in our solar system at least have those properties. Not to mention Sun makes <em>99.86% of our solar system </em>combined.
