the answer would be B) displacement of particles is perpendicular to the direction of wave motion
Answer:
θ = 33°
Explanation:
Here, we can use the formula for the total time of flight of a projectile to calculate the launch angle of frog:
where,
θ = launch angle = ?
T = Total time of flight = 0.6 s
g = acceleration due to gravity = 9.81 m/s²
u = launch speed = 5.4 m/s
Therefore,
<u>θ = 33°</u>
D. because the statue has a new chemical called patina. It is no longer copper.
KE = 10 joules
ke = 1/2 x 0.8 x 5 x v2
