Answer:
The value is 
Explanation:
From the question we are told that
The efficiency of the carnot engine is 
The efficiency of a heat engine is 
The operating temperatures of the carnot engine is 
to 
The rate at which the heat engine absorbs energy is 
Generally the efficiency of the carnot engine is mathematically represented as
![\eta = [ 1 - \frac{T_1 }{T_2} ]](https://tex.z-dn.net/?f=%5Ceta%20%3D%20%20%5B%201%20-%20%5Cfrac%7BT_1%20%7D%7BT_2%7D%20%20%5D)
=> ![\eta = [ \frac{T_2 - T_1}{T_2} ]](https://tex.z-dn.net/?f=%5Ceta%20%3D%20%20%5B%20%5Cfrac%7BT_2%20-%20T_1%7D%7BT_2%7D%20%5D)
=> 
Generally the efficiency of the heat engine is
=> 
Generally the efficiency of the heat engine is also mathematically represented as
Here W is the work done which is mathematically represented as
Here 
is the heat exhausted
So
=> 
=>
Based on your question where a car leaves skid marks 85m long on the highway nad getting to stop. The deceleration of the car is 3m/s^2 to estimate the speed of the car just before braking first is to analyze the problem then apply the necessary formulas. the possible answer is 510m/s
Helium... from the greek word helios... the sun
<span>selenium... from the greek word selene... the moon </span>
<span>palladium.. after the asteroid pallas </span>
<span>tellurium...from the greek word tellus... the earth </span>
<span>mercury...after the planet mercury </span>
<span>cerium... after the asteroid ceres </span>
<span>uranium...after the planet uranus </span>
<span>neptunium.. after the planet neptune </span>
<span>plutonium.. after the planet pluto</span>
Answer:
The graph appears to be in error.
The actual figure appears to be a rhombus with sides of 5 and 15 with a height of 5
The work done (F * S) is the area of the rhombus
1/2 * (5 +15) * 5 = 50 J
Answer:
Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container.
Explanation:
The pressure at any point in the fluid is equal in all directions.
