Answer:0.27*10^{6} (m)
Explanation:
with a wave we know that speed= wavelenght* frecuency so
wavelenght= 3*10^{7} / 109 = 0.27*10^{6} (m)
Selection D makes most sense
Answer:
The distance traveled by the ball before it lands in the other player's glove is 130.96 m.
Explanation:
Given;
angle of projection of the ball, θ = 40⁰
initial velocity of the ball, u = 36.1 m/s
The distance traveled by the ball before it lands in the other player's glove is the range of the projectile, calculated as follows;

Therefore, the distance traveled by the ball before it lands in the other player's glove is 130.96 m.
Power = voltage(V) * current(I)
= 120 * 0.5
Power = 60 watts
