A) The design team is evaluating different materials because the first Law of
Thermodynamics states that energy transfer is always 100% efficiency.
B)
The design team is evaluating different materials because the law of
conservation of matter states that electricity cannot be generated from
matter.
The design team is evaluating different materials because the second law
of Newtonian motion states that power is equal to work performed per unit
time.
The design team is evaluating different materials because the second Law
of Thermodynamics states that energy transfer always includes a loss of
usable energy
D)

Please Help me

i believe it is b. what was the cause of the big bang

hope this !

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
