How much mass does the sun lose through nuclear fusion per second?

An object starts from rest at point f and speeds up continuously as it moves around an oval. a. choose a point about 1/8 th of the way around the oval from point f, and label it point g. draw a vector to represent the velocity of the object at point g. b. determine the change in velocity vector   between points f and g.

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

Anybody wanna ? (picture included? )
