Answer:

.conserves kinetic energy and momentum

.does not coalesce

.causes much lesser deformation as compared to inelastic

.the two bodies involved; after collision move with separate final velocities.

Explanation:

eg. throwing a ball at a wall

<em>collision</em><em> </em><em>between</em><em> </em><em>a</em><em> </em><em>punch</em><em> </em><em>and</em><em> </em><em>your</em><em> </em><em>nose</em><em>,</em><em>haha</em>

<em>I</em><em> </em><em>guess</em><em> </em><em>that</em><em> </em><em>will</em><em> </em><em>cause</em><em> </em><em>a lot</em><em> </em><em>deformation</em><em>.</em><em>.</em>

Why do you think this appeal system is necessary in the legal system?
MatroZZZ [7]

Appeal system enables the higher court to review the case once again. Possible situation for appeal arises when the defendant consider punishment very tough.

<u>Explanation:</u>

The Appeal system is very important in the legal system. Appeal means a process which helps in reviewing the cases. In case of the appeal, a request is made to a higher court to look into the case once again.

A cylinder fitted with a piston exists in a high-pressure chamber (3 atm) with an initial volume of 1 L. If a sufficient quantit
Bess [88]

Answer:

C. 85%

Explanation:

A cylinder fitted with a piston exists in a high-pressure chamber (3 atm) with an initial volume of 1 L. If a sufficient quantity of a hydrocarbon material is combusted inside the cylinder to produce 1 kJ of energy, and if the volume of the chamber then increases to 1.5 L, what percent of the fuel's energy was lost to friction and heat?

A. 15%

B. 30%

C. 85%

D. 100%

work done by the system will be

W=PdV

p=pressure

dV=change in volume

3tam will be changed to N/m^2

3*1.01*10^5

W=3.03*10^5*(1.5-1)

convert 0.5L to m^3

5*10^-4

W=3.03*10^5*5*10^-4

W=152J

therefore

to find the percentage used

152/1000*100

15%

100%-15%

85% uf the fuel's energy was lost to friction and heat
