<h2>
Answer: 1.25 km</h2>
Explanation:
The velocity 
of a wave is given by:
(1)
Where:
is the wavelength of the wave
is the frequency of the wave. Its unit is Hertz (
)
So, we have to find from equation (1):
(2)
Finally we obtain the wavelength of the earthquake wave:
Answer:
calar quantity, length of path. displacement: vector quanity, "as the crow flies" difference between start and finish regardless of path taken. Term.
Explanation:
Answer:
156.1 rad/s = 24.8 rev/s
Explanation:
Torque = Momentum of inertial × radial acceleration = Iα
τ = 26.6 N.m
I = 0.162 kg.m²
26.6 = 0.162 × α
α = 164.2 rad/s²
Using equations of motion,
θ = 11.8 rev = 11.8 × 2π = 74.2 rad
w₀ = 0 rad/s (since the grindstone starts from rest)
w = ?
α = 164.2 rad/s²
w² = w₀² + 2(α)(θ)
w² = 0² + (2×164.2)(74.2)
w = 156.1 rad/s = 24.8 rev/s
Hope this Helps!!!
That is the wrong attiude!....dipwad.
Given data
efficiency (η) = 65 %
= 0.65
Machine provides (Work done by the machine) = 1300 × 50
= 65000 J
efficiency (η) = work done by the machine ÷ work supplied to the machine
0.65 = 65000 ÷ Input work
Input work = 100000 J
= 100 KJ
