Answer:
Maximum height = 1.27 m
Explanation:
Given:
θ = 30°
Speed = 10 m/s
Find:
Maximum height
Computation:
Maximum height = v²(sinθ)² / 2g
Maximum height = 10²(sin30)² / (2x9.81)
Maximum height = 1.27 m
Qualitative data would be taken in this investigation. This is because the effect of the cold temperature on the leaves can not be measured quantitatively, but can be observed in the leaves' appearances. The qualitative data may include how green the leaf looks or how upright and rigid it is. The readings would be taken for leaves with and without snow.
I think the correct answer from the choices listed above is the first option. One of the challenges of wind power is the <span>location of wind farms. Wind farms require large areas in order to function. It consumes a lot of space. Hope this answers the question.</span>
Answer:
f = 2 f₀
Explanation:
A mass-spring system has angular velocity
w = √ k / m
The angular velocity is related to the frequency
w = 2π f
f = 1 /2π √k / m
If we change the mass for another that is ¼ of the initial mass
m = ¼ mo
We replace
f = 1 / 2π √(k 4 / mo)
f = (1 / 2π √k/m₀) √ 4
f = 2 f₀
In summary the frequency doubles from the initial frequency
Answer: v = 43.98 m/s
Explanation: 22 + 15.7x1.4 = 43.98.
Hope this helps!
