usually, the fuel pump turns on, along with all of the vehicle's electric systems, but on a large diesel engine, like in a semi, or agricultural equipment, the intake, and carburetor are activated first to allow diesel (fuel) into the engine to combustion can be produced once the engine turns over

A closed system consisting of 10 lb of air undergoes a polytropic process from p1 = 75 lbf/in2, v1 = 4 ft3/lb to a final state w
Vitek1552 [10]

Answer:

The polytropic exponent (n) is 1.2

The amount of energy transfer by work is 552.45 Btu

Explanation:

P1V1^n = P2V2^n

P1 = 75 lbf/in^2 = 75 lbf/in^2 × 143.3 in^2/ft^2 = 10,747.5 lbf/ft^2

V1 = 4 ft^3/lb × 10 lb = 40 ft^3

P2 = 20 lbf/in^2 = 20 × 143.3 = 2866 lbf/ft^2

V2 = 12 ft^3/lb × 10 lb = 120 ft^3

(V2/V1)^n = P1/P2

(120/40)^n = 10747.5/2866

3^n = 3.75

ln 3^n = ln 3.75

n ln 3 = ln 3.75

n = ln 3.75/ln 3 = 1.2

W = (P2V2 - P1V1)/1 - n = (2866×120 - 10747.5×40)/1-1.2 = (343,920 - 429,900)/-0.2 = -85,980/-0.2 = 429,900 lbf.ft = 429,900/778.17 Btu = 552.45 Btu

If a golf ball and a ping-pong ball both move with the same kinetic energy, which has the greater speed?.
Digiron [165]

Given what we know, if a golf ball and a ping-pong ball both move with the same kinetic energy, the ping-pong ball must be traveling at a greater speed.

<h3>How do we know that the ping-pong ball is faster?</h3>
  • This has to do with the formula for kinetic energy.
  • The formula is  KE= 1/2 *m * v^2.
  • This means that mass and velocity are proportional.
  • If the total Kinetic energies are equal, the object with the lower mass must have a higher velocity.
  • Since ping-pong balls are known to have very little mass, we know it must be traveling faster.

Therefore, we can confirm that if a golf ball and a ping-pong ball both move with the same kinetic energy, the ping-pong ball must be traveling at a greater speed due to its lower mass and the relationship between mass and speed when calculating kinetic energy.
