Answer:
Average Velocity = 3.65 m/s
Explanation:
Average Velocity

Answer:
F=5.7×10⁻⁶
Explanation:
Not knowing a formula outright, I decided to follow the units of some relationships I did know. Radiation pressure is defined as force per area and also intensity divided by velocity (the speed of light here of course). Breaking intensity down into power per area and isolating force gave me the relationship F=(Power/Velocity),where power is given and the velocity is a constant.
My work is in the attachment, where I double checked the units too, comment with any questions.
Answer:
9.495 m/s
Explanation:
initial horizontal speed, ux = 2.60 m/s
initial vertical speed, uy = 0
height, h = 4.60 m
acceleration due to gravity, g = 9.8 m/s^2
Let the speed of fish is v as it hits the water level.
Use third equation of motion in vertical direction


v = 9.495 m/s
Thus, the fish hits the water level with the speed of 9.495 m/s.
The duck is not carried by the wave motion because <span>Waves move energy through a medium but don't transfer particles. So when the waves pass by a duck floating on a lake, the duck just bobs up and down, but remains in its place.</span>
