Answer:
t = 0.6933 s
Explanation:
This is a rotational kinematics exercise, let's find the angular acceleration of the wheel
w² = w₀² + 2 α θ
α = (w² - w₀²) / 2 θ
Let's reduce the angles to the SI system
θ = 16 rev (2π rad / 1 rev) = 32π rad
let's calculate
α = (105² - 185²) / (2 32π)
α = -115.39 rad / s²
now let's use the relation
w = w₀ + α t
t = (w- w₀) /α
t = (105 - 185) / (- 115.39)
t = 0.6933 s
D) There will be less available for other living things.
The rate at which the person is now losing thermal energy is 99 J/s.
<h3>
Thickness of the person's skin</h3>
The thickness of the person's skin is calculated as follows;
Q = k(ΔT)h
where;
- k is thermal conductivity
- h is thickness of the person's skin
- ΔT difference in temperature across the skin = 30 °C = 303 K
h = Q/k(ΔT)
h = (120) / (0.22 x 303)
h = 1.8 m
<h3>Rate at which the person is now losing thermal energy</h3>
Q = k(ΔT)h
where;
- ΔT is new temperature difference across the skin = 33 °C = 306 K
Q = (0.18)(306)(1.8)
Q = 99 J/s
Thus, the rate at which the person is now losing thermal energy is 99 J/s.
