The compound NaCl (salt) has the same properties as sodium (Na) and chlorine (CI) because it is made of both of those elements. True False

13.79 revolutions

Explanation:

Velocity of ball = v = 34.5 m/s

Spin rate of ball = 26 revolutions/s

Distance between home plate and pitching mound = s = 18.3 m

Time taken by the ball to reach the home plate = t

Number of revolutions the ball completes is

∴Number of revolutions the ball completes before reaching home plate is 13.79
