We know, dₓ α n² d₁
For n = 15 (15th Orbit)
It would be: d₁₅ = 15² * 1.06
d₁₅ = 238.5 A
In short, Your Answer would be: 238.5 A
Hope this helps!
Answer:
The Richter Scale is used to define the power of earthquakes, it was created by Charles Ritcher in the 1930s to work as a seismogram, regulated and assessed by a seismometer, which responds to ground motions at a distance of around 62 miles from the event, and records the seismograph, a <em>base 10</em> logarithmic scale.
Thereby the most suitable options are <em>A)</em><em>, </em><em>B)</em><em> </em>&<em> </em><em>D)</em><em>.</em>
Answer:
Explanation:
Heat absorbed by oil
= mass x specific heat x rise in temperature
= 30 x 10⁻³ x 950 x 2.2 x 10³ x ( 50-10 )
= 25.08 x 10⁵ J
Heat absorbed by air
= 50 x 1.2 x 1.0054 x 10³ x ( 20-10 )
= 6.03 x 10⁵ J
Total heat absorbed = 31.11 x 10⁵ J
If time required = t
heat lost from room
= .35 x 10³ t
Total heat generated in time t
= 1.8 x 10³ t
Heat generated = heat used
1.8 x 10³ t = .35 x 10³ t + 31.11 x 10⁵
1.45 x 10³ t = 31.11 x 10⁵
t = 31.11 x 10⁵ / 1.45 x 10³
t = 2145.5 s
Answer:
Explanation:
given,
rotational inertia, I = 474.0 kg·m²
decrease in angular velocity
ω₁ = 26.2 rad/s ω₂ = 0 rad/s
time = 204 s
torque = ?
α = 0.128 rad/s²
frictional torque acting by the flywheel is equal to 60.88 N.m
