Answer:
25.2 m/s
Explanation:
∑F = ma
Nμ = m v² / r
mgμ = m v² / r
gμ = v² / r
(9.8 m/s²) (0.81) = v² / 80 m
v = 25.2 m/s

You are looking at yourself in a plane mirror, a distance of 3 meters from the mirror. your brain interprets what you are seeing in the mirror as being a person standing 6 meters from you.
<h3>Calculation</h3>
The plane mirror shows an exact replica of the real world. that means the distance of you from the mirror is the same distance as your reflection form the mirror at the opposite side of the mirror.
Thus, distance of image from the plane mirror is same as the distance of object (person) from the plane mirror but the image is formed behind the mirror.
Thereby we have v=u=3 m
Thus, distance between image and the person
is d = v + u = 3 + 3 = 6 m
Thus, the person is 6 meters away from the image.

Answer:
c)Tidal forces from the planet prevent them from accreting.
Explanation:
According to the Roche limit and Hill spheres limit Saturn's rings are too close to the planet. This causes the tidal forces to tear the particles i.e., accretion will not start.
This can be even noticed in the rings itself. The C ring of Saturn which is closer to the planet has unclumped particles while in the B ring you can observe clumping.
