A projectile of mass 0.877 kg is shot straight up with an initial speed of 27.3 m/s. (a) How high would it go if there were no air resistance? (b) If the projectile rises to a maximum height of only 8.49 m, determine the magnitude of the average force due to air resistance.

Hydrogen and helium are both members of?

Sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) attraction that bonds them together.

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
