Given 28.2 grams of an unknown substance, if the substance absorbs 2165 joules of energy and the temperature increases by 35 kelvin, what is the specific heat of the substance? 2.14 x 106 j/g·k 2.19 x 100 j/g·k 5.73 x 10-4 j/g·k 2.69 x 103 j/g·k if someone could tell me how to do it as well, it would be greatly appreciated.

Why is retrograde motion an apparent motion

Ajet plane is speeding down the runway during takeoff. air resistance is not negligible. identify the forces on the jet.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
