crimeas [40]

Answer:

a) V = 252 cm³

b) Vs = 72 cm³

Explanation:

a)

The volume of the water can be given by the following formula:

Volume\ of\ Water = V = (Base\ Area)(Height)\\V = (Length)^2(Height)\\V = (6\ cm)^2(7\ cm)\\

<u>V = 252 cm³</u>

<u></u>

b)

The volume of stone can be given by the change in volume of the water when the stone is dipped into it.

Volume\ of\ Stone = Vs = (Length)^2(Change\ in\ Height\ of\ Water)\\Vs = (6\ cm)^2(9\ cm - 7\ cm)\\

<u>Vs = 72 cm³</u>

A man of mass 85 kg runs up a flight of stairs of height 4.6 m in a time period
seraphim [82]

Explanation:

a) Power = work / time = force × distance / time

P = Fd/t

P = (85 kg × 9.8 m/s²) (4.6 m) / (12 s)

P ≈ 319 W

b) P = Fd/t

0.70 (319 W) = (m × 9.8 m/s²) (4.6 m) / (9.6 s)

m = 47.6 kg
