Answer:
(a) W=217 J
(b) Tc=378K
(c) e=0.39=39%
Explanation:
For part (a)
We to calculate the mechanical work W the engine does. By knowing QC and QH can obtain the work using equation
W = IQHI — IQcl .....................eq(1)
Put given values for QH and QC into equation (1) to get
the mechanical work of the engine
W = 550 - 335
W=217 J
For part (b)
We want to determine the temperature of low temperature reservoir which means Tc
IQc|/|Qh| =TC/TH
for Tc
Tc=(IQc|/|Qh|)*TH
Now we can put values
Tc= 620K (335/
550.1)
Tc=378K
For part (c)
Here we want to find the thermal efficiency (e) of the cycle
e=1-TC/TH
e=1-(378/620)
e=0.39=39%
Because it generates high amounts of energy for a small amount of material, and doesn't produce as much pollution as fossil fuels.

Explanation:
Linear acceleration is a type of acceleration of a body along a straight path or line.
Acceleration is defined as the rate of change of velocity with time.
Acceleration = 
There are different types of acceleration .
- linear acceleration is used to describe the rate of change of velocity of a body along a straight path with time.
- centripetal acceleration is the rate of change of velocity of a body traveling along a circular path with time. It is directed towards the center.
- Angular acceleration is the rate of change of angular velocity.
