You need to purchase a motor to supply 400 joules [J] in 10 seconds [s]. All of the motors you can choose from are 80% efficient
kondor19780726 [428]

Answer:

32 W.

Explanation:

Power: This can be defined as the ratio of energy to time. The S.I unit of power is watt(W). The formula for power is given as,

P = W/t.................... Equation 1

Where P = power, W = work done, t = time.

Given: W = 400 J, t = 10 s.

Substitute into equation 1

P = 400/10

P = 40 W.

If the motors that is choose is 80% efficient,

P' = P(0.8)

Where P' = minimum power

P' = 40(0.8)

P' = 32 W.

A roof tile falls from rest from the top of a building. An observer inside the building notices that it takes 0.28 s for the til
PIT_PIT [208]

Answer:0.246 m

Explanation:

Given

height of window (h)=1 m

Time to pass window =0.28 s

Let roof is at a distance of h_0 above window

let t be the time to cover h_0

h_0+1=\frac{g(t+0.28)^2}{2}------1

h_0=\frac{gt^2}{2}--------2

subtract 1 & 2

1=\frac{g(t+0.28)^2}{2}-\frac{gt^2}{2}

1=\frac{g}{2}\left [ \left ( 2t+0.28\right )\left ( 0.28\right )\right ]

t=0.224 s

h_0=\frac{9.8\times 0.224^2}{2}

h_0=0.246 m
