The work done by the elephant to lift one log is the force multiplied by the height at which the log has been lifted:
And so, the total work done to lift the 7 logs is 7 times the work done to lift each log:
Answer:
Explanation:
the object will not move as the force exerted is not sufficient enough to overcome its force of friction
N2O is nitrous oxide becuase of the nitrogen and oxygen
Answer:
Explanation:
wavelength, λ = 2.5 m
speed, v = 13.8 m/s
Amplitude, A = 0.14 m
The general equation of the transverse harmonic wave which is travelling right is given by
where, Ф is phase
At t = 0, x = 0 , y = 0.14 m
0.14 = 0.14 Sin Ф
Ф = π/2
So, the equation is
