What is impulse? How does this relate to momentum?

Molecular clouds range in mass from a few times the mass of our Sun (solar masses) to 10 million solar masses. Individual stars range from 0.08 to about 150 solar masses. What does all of this imply about how stars form from molecular clouds

A driver wearing a seat beat decelerates at roughly the same rate as the car it self. Since many modern cars have a "crumble zone" built into the front of the car, let us assume that the car decelerates of a distance of 0.9 m.

A truck moving at 36 m/s passes a police car moving at 45 m/s in the opposite direction. If the frequency of the siren is 500 Hz relative to the police car, what is the change in frequency (in Hz) heard by an observer in the truck as the two

A transverse wave on a rope is given by y (x, t) = (0.750cm) cos (π[ (0.400cm-1) x + (250s-1) t]). find the period

Which best describes why a physical change differs from a chemical change? A. A physical change predicts the behavior of a substance when in a reaction, whereas a chemical change is used to identify characteristics of a substance. B.
