The amplitude of a wave is the distance from the center of the wave to one of its peaks or one of its troughs. The distance from center to peak or center to trough is the same, therefore the top-to-bottom distance is simply twice the wave's amplitude, 8.0m
8. ionic bond because lithium is a metal and oxygen is a non metal.
9. covalent bond because sulfur and oxygen are both non metals.
10. covalent
11. ionic
Given that,
Angle = 30°
Initial velocity = 15 m/s
We need to calculate the time of flight
Using formula of time of flight

Where, u = initial velocity
g = acceleration due to gravity
Put the value into the formula


We need to calculate the final velocity of the ball
Using equation of motion



Hence, The final velocity of the ball is 29.7 m/s.
