Answer:
Angle of twist;Φ = (to•L²)/Gπc⁴
Explanation:
I have attached the explanation.
However, I used D for radius of shaft against c used in the question. So, if we replace the D with c, we'll have;
Φ = (to•L²)/Gπc⁴
Answer:
0.04455 Hz
Explanation:
Parameters given:
Wavelength, λ = 6.5km = 6500m
Distance travelled by the wave, x = 8830km = 8830000m
Time taken, t = 8.47hours = 8.47 * 3600 = 30492 secs
First, we find the speed of the wave:
Speed, v = distance/time = x/t
v = 8830000/30492 = 289.58 m/s
Frequency, f, is given as velocity divided by wavelength:
f = v/λ
f = 289.58/6500
f = 0.04455 Hz
T1 = 2×W / squrt (3) +1
T2 = squrt(6) ×W/ squrt (3) +1
Here, T1 is along A.
T2 is along B
W = 250N.
Yo can directly use above formula to find solution.
Answer:
Explanation:
velocity of ship with respect to water = 6.5 m/s due north
velocity of water with respect to earth = 1.5 m/s at 40° north of east
velocity of ship with respect to water = velocity of ship with respect to earth - velocity of water with respect to earth
The magnitude of the velocity of ship relative to earth is = 5.66 m/s
<span>Buddy, remember one formula.. speed=distance/time
your all problems will be solved.
in this case the answer is 5 km per hr</span>
