A car moving with constant acceleration covers the distance between two points 180 m apart in

patriot [66]

distance = 180m

time = 6 secs

velocity = 45m/s

s= ut+ 1/2at²

2s=2ut+at²

2s-2ut= at²

2(180)-2(25)(6) =a(6)²

60=36a

1.66666 m/s² = a

What is the efficiency of an engine that exhausts 440 J of heat to a cold reservoir and receives 570 J of heat from a hot reserv

katrin2010 [14]

Answer:

Efficiency = 77%

Explanation:

Input energy = 570 J

Output energy = 440 J

To find the efficiency;

$Efficiency = \frac {Out-put \; energy}{In-put \; energy} * 100$

Substituting into the equation, we have;

$Efficiency = \frac {440}{570} * 100$

$Efficiency = 0.7719 * 100$

Efficiency = 77.19 ≈ 77%

Therefore, the efficiency of the engine is 77 percent.
