Acylinder of pet with the radius of 0.5 cm and a length of 10 cm is subjected to a force of 4 kn . after this force is applied, the length of the cylinder becomes 10.2 cm.

a. calculate the stress and strain on this cylinder.

b. assuming the deformation is purely elastic, calculate the modulus of pet.

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//

conduct current i mean it makes sense

just took the test its not "d"

if i am correct, your answer choices are:

a. the temperature remains constant

b. the temperature increases at a constant rate

c. heat flows at a constant rate into the system

d. heat flows at a constant rate out of the system

e. no heat flows into or out of the system

if so, then the answer is e. no heat flows into or out of the system.
