the net torque about the point (-1 m, 1 m) is 4 N-m.
The resultant force acting on the object is calculated as
R^2=(-5+3)^2+2^2=2.82 N
Distance of the point from the resultant force
d^2=(-1)^2+1^2=1.414
The net torque acting on the point (-1 m, 1 m) is
T=2.82×1.41=3.98 N-m
Answer:
I just doing this because a I want points so hello halajsojaj sha lajajapajsjaljsja que te valla bien ;)
Answer:
70 m/s
Explanation:
The frequency of earthquake = 2.0 Hz
The wavelength = 35 m
How fastbthw earthquake is t traveling is given bythw velocity of the wave, velocity of wave is related to frequency and wavelength using the formula :
V = frequency * wavelength
V = 2 * 35
V = 70 m/s
