Answer:
<h2> The refracted angle is r= 34.47°</h2>
Explanation:
According to snell's law the incident normal and refracted ray at the point of incidence all lie in the same plane
Given
incident angle i= 60°
refracted angle r= ?
index of refraction u= 1.53.
Applying the formula
solving for r
r= 34.47°
Answer:
A 50 kg ball traveling at 20 m/s would have 4 times more kinetic energy.
A 50 kg ball traveling at 5 m/s would have 4 times less kinetic energy.
A 50 kg person falling at 10 m/s would have the same kinetic energy.
Explanation:

Brendan drew a diagram to illustrate the centripetal force acting on a satellite.
How can Brendan correct his diagram?
Draw the Fg = Fc vector so it points at a 45° angle from the v vector.
Change the Fg = Fc vector label so it reads Fa = Fc.
Draw the Fg = Fc vector so it is longer than the v vector.
Change the Fg = Fc vector so it is perpendicular to the v vector.
D is the answer
Answer:
Mia is correct, but did not show a lot of work.
Explanation:
Mia must explain her answer and give reasoning by using what knowledge she has on the subject.
Answer:
The location of helicopter is behind the packet.
Explanation:
As the packet also have same horizontal velocity as same as the helicopter, and also it has some vertical velocity as it hits the ground.
The horizontal velocity remains same as there is no force in the horizontal direction. The vertical velocity goes on increasing as acceleration due to gravity acts.
So, the helicopter is behind the packet.
