Reactions occur within the sun to transform what energy in

These are equal and opposite forces that do not cause a change in position or motion.

Isotopes are atoms with identical numbers of __ and different numbers of __. protons; electrons neutrons; protons electrons; neutrons protons; neutrons

A car is travelling at a velocity of 15 m/s due north speeds up uniformly to a velocity of 30 m/s in 3 seconds. calculate its accelartion.

A plane is traveling at north east direction, 30° regard to the north. if not wind it could travel at 60 m/s but it results that there is wind going to the east at 20 m/s. determine the resulting speed of the plane regard to earth.

When distances were carefully measured from Earth to globular clusters above and below the Milky Way plane (where our view of them is not obscured by interstellar dust and gas), their distribution was found to be

Imagine you transfer heat into a gas. This heat splits up in two different ways: Additional thermal energy making the gas hotter and "fuel" for the gas to do work. Let's suppose, 64% of the transferred heat transforms into thermal energy.

How much heat is absorbed by a 61g iron skillet when its temperature rises from 5oC to 29oC?

Explain the relationship between motion and frame of reference.

Two students are looking at a brightly lit full Moon, illuminated by the reflected light from the Sun. Consider thefollowing discussion between the two students about what the spectrum of moonlight would look like.
