Answer:
215.6Nm
Explanation:
The figure below shows a 10-kg mass hung from the end of a rod that is 2.2 m in length. Find the magnitude of the torque produced by the hung mass (m)
Torque = Force × radius
Torque = mg × radius
Torque = 10(9.8) × 2.2
Torque = 98 × 2.2
Torque = 215.6Nm
The answer is that it showed the scientist that on the area of the mantle from the subduction zones the slabs of the ocean floor remains or returns after such tectonic movement or earthquakes.
Answer:
a) I = 3.63 W / m²
, b) I = 0.750 W / m²
Explanation:
The intensity of a sound wave is given by the relation
I = P / A = ½ ρ v (2π f )²
I = (½ ρ v 4π² s_{max}²) f²
a) with the initial condition let's call the intensity Io
cte = (½ ρ v 4π² s_{max}²)
I₀ = cte s² f₀²
I₀ = cte 10 6
If frequency is increase f = 2.20 10³ Hz
I = constant (2.20 10³) 2
I = cte 4.84 10⁶
let's find the relationship of the two quantities
I / Io = 4.84
I = 4.84 Io
I = 4.84 0.750
I = 3.63 W / m²
b) in this case the frequency is reduced to f = 0.250 10³ Hz and the displacement s = 4 s or
I = cte (f s)²
I = constant (0.250 10³ 4)²
I = cte 1 10⁶
the relationship
I / Io = 1
I = Io
I = 0.750 W / m²
Example: A apple rotting.
If I put my apple in a fridge, then it would not rot as fast because it is in a cooled area. (example)
