Answer:
16.63265306 Kg
Explanation:
This is a Newtons to weight conversion.
Fg = weight
Fg = N/9.8
Answer:
V_{average} =
, V_{average} = 2 V
Explanation:
he average or effective voltage of a wave is the value of the wave in a period
V_average = ∫ V dt
in this case the given volage is a square wave that can be described by the function
V (t) = 
to substitute in the equation let us separate the into two pairs
V_average = 
V_average = 
V_{average} = 
we evaluate V₀ = 4 V
V_{average} = 4 / 2)
V_{average} = 2 V
Impulse is the interval of a force ,f,over the time interval ,t,for which it acts
Formula p=f t
Momentum is the quantity of motion of a moving body measured as a product of its mass and velocity
Formula p=m v
P=momentum
M=mass
V=velocity
