Answer: P = 40 W
Explanation: Power is defined as the amount of work per unit time or expressed in the formula of P = W /t
Work is the product of force and distance so W = Fd.
So the working equation will be:
P = Fd / t
= 20 N ( 2.0 m) / 1 s
= 40 W
Is the amount of power exerted.
Antelope: uniform motion => V = d/t => d = Vt = 7m/s * t
Lion: uniformly accelerated motion, with initial velocity = 0 => d = [1/2]a*t^2 = [1/2]*[5m/s^2]*t^2
7*t = 2.5*t^2=> 2.5t^2 - 7t =0 => t(2.5t - 7) = 0
2.5t - 7 = 0 => t = 7/2.5 = 2.8 m/s^2
Answer:
v = 2.974
Explanation:
Perhaps the formula should be
v = √(2*g*d (sin(θ) - uk*cos(θ) ) This is a bit easier to read.
v = √(2* 9.80*0.725(0.707 - 0.12*0.707) ) Substitute values. Find 2*g*d
v = √14.21 * (0.707 - 0.0849) Figure out Sin(θ) - uk cos(θ)
v = √14.21 * (0.6222)
v = √8.8422 Take the square root of the value
v = 2.974
Answer:
electric potential energy=
so the electric potential energy and distance(r) are inversely proportional.
then, the greatest energy occur in the smallest distance b/n the two balloon.
Answer: The complexity of filter is the order of the filter. Greater the order of the filter, more efficient the filter is. Roll of value of one filter is 20dB/dec. So the roll-off value of 8th order filter is 160dB/dec. 8th order filter is more efficient than the second order low-pass filter.
