A change of colour, heat being released or fizzing (a gas being released)
Answer:
20 m/s
Explanation:
The frictional force the road exerts on the car provides the centripetal force that keeps the car in circular motion along the curve:
where
F is the centripetal force
m is the mass of the car
r is the radius of the curve
v is the speed of the car
In this problem we have:
m = 2000 kg
r = 200 m
F = 4000 N is the maximum force
Re-arranging the equation, we can calculate the maximum speed v corresponding to this force:
The overall efficiency of this plant will be 83%. The plant's efficiency is calculated by dividing work output to that of heat supplied.
<h3>What is efficiency of the plant?</h3>
The efficiency of the plant is found as the ratio of work output to the heat supplied.
The heat supplied is found as;
Q= m h
Q=30,000 kJ/kg,× 60 tons/h
Q=30,000 ×10³×60×10³/3600
Q=3×10⁷×16.66
Q=180.720×10⁶
Q=180 mw
The overall efficiency of this plant is ;
The overall efficiency of this plant will be 83%.
