a shot putter accelerates a 7.3kg shot from rest to 14m/s in 1.5r seconds. what average power was developed?

Sedaia [141]

Explanation:

$power = \frac{energy \: expended}{time}$

m = 7.3kg

u = 0

v = 14m/s

t = 1.5sec

P = (0.5×7.3×14²) ÷ 1.5

P = 476.93

P = 477 watt

if a toaster oven uses 1000 J of electrical energy to produce 800 J of thermal energy, what is the percent efficiency of the toa

ArbitrLikvidat [17]

Answer:

80%

Explanation:

The thermal energy output by the oven is 800 J which is the useful energy that can be utilized for cooking.

The electrical energy input to the oven is 1000 J.

The efficiency of the oven =

(Useful energy output)/(Total energy input to the oven) x 100

$=\frac{800}{1000}\times 100= 80\%$

Hence, the efficiency of the oven is 80%.
