Answer:
Explanation:
Given that d = 0.11cm = 0.0011m, l = 2.2m, extension = 1.24cm = 0.0124m, mass = 34kg
force = 34 x 9.81 = 333.54N, Area = Pi x d²/4 = 3.142 x 0.0011^2/4 = 9.505x10^-7m²
Calculate the stress = Force/Area = 333.54N / 9.505x10^-7m²
= 350926661.4N/m²
calculate the strain = extension/original length
= 0.0124 / 2.2 = 0.00563
Young modulus of elasticity = Stress/Strain = 350926661.4N/m² / 0.00563
= 6.2332 x 10^10Pa
Answer:
B) Water does not soak into the ground
Explanation: A runoff is when the water does not get soaked into the water after any type of perciptation. ex: rain or snow. The water in an runoff is from the water that the land couldn't absorb.
Answer:
I believe you're missing the decomposers
Explanation:
Answer:
Yes
Explanation:
In natural systems, both energy and matter are conserved within a system. This means that energy and matter can change forms but cannot be created or destroyed.
I think the answer is B because when you think of wind as an energy source you think of wind turbines,, the big things that turn high in the sky. And since it’s in the sky, birds and other flying animals can fly into it and die. Furthermore it can’t be A since wind energy doesn’t use radioactive material, for C I do not believe it uses ground water, and for D the small greenhouse gas emissions it may make to convert the wind energy into electricity (it might not produce any, it depends on how far science has come in the past few years) would be nothing compared to the amount produced burning coal or using gasoline or something like that.
