Radio waves, Middle-C, and halitosis are not forms of light.
Answer:
Explanation:
1) The time of flight equation for projectile motion can be used here to find total time in air.
t = 2vsin∅ / g
where v is speed, Ф is launch angle
t = 2×4×sin 60 / 9.8
t = 0.71 seconds
2) Distance where it hit the ground is called as range and has the following standard equation
D = v² sin2Ф/g
D = 4²sin 2×60 / 9.8
D = 1.41m
3) Maximum elevation is maximum time reached
h = v² sin²Ф / 2g
h = 4²sin² 60 / 2*9.8
h = 0.61 m
If it is in its ground state, it will be in the level 1s
An organism that lives in or on an organism of another species (its host) and benefits by deriving nutrients at the other's expense.
Low frequency, low amplitude, or both.
