A revolution equals 2*pi radians.
As the wheel rotates half every 4 seconds, then it means that it rotates half revolution.
Thus, the angular velocity of the wheel is given by:
w = (pi) / (4) = 0.79 rad / sec
answer
The wheel's angular velocity is 0.79 rad / sec
dimensions of the bed is given as
now the volume of the bed is given as
now the mass of water in it is given as
<em>so it will contain 1581 kg mass in it</em>
A chemotroph gains its energy by eating something else
Answer:
<-0.45, 0, 0> kgm/s
Explanation:
The change in momentum would equal to the impulse generated by force F = <-0.3, 0, 0> over time duration of Δt = 1.5 second. The impulse is defined as the product of force F and the duration Δt
So the change in momentum is <-0.45, 0, 0> kgm/s
