Answer:
Follows are the explanation to this question:
Explanation:
In this solution, it is defined that there are two principal motions for the moon, which are its revolution as well as rotation. In such a movement called revolution, its Moon is relocating around the Earth, in which the approximate movement of the moon from around earth has an average movement of about 13.2° per day, or 92 degrees every week, that's once in 27.3 days.
Answer: no definite shape (takes the shape of its container)
no definite volume.
particles move in random motion with little or no attraction to each other.
highly compressible.
Explanation:
Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form.
Answer:
b) The light slows down and it changes direction towards the perpendicular.
Explanation:
Light travels at different speed in different mediums.
Refractive index is equal to velocity of the light 'c' in empty space divided by the velocity 'v' in the substance.
Or ,
n = c/v.
Light travels at a slower speed in water as compared to air because there are more number of interfering molecules in the path of the light in case of water as compared to liquid.
<u>When a light travels from lower denser medium say water to higher denser medium say water, it bends towards the perpendicular as its speed reduces in that medium.</u>
Let L = length of the swing.
Let the lowest position of the swing be the reference point.
Therefore in the lowest position,
The height of the swing = 0,
The support for the swing is at height = L.
At 32° swing relative to the vertical,
The height of the swing is
A = L - Lcos(32°) = L[1 - cos(32°)] = 0.152L
Answer:
The amplitude is 0.152*L, where L = length of the swing.
Answer:
Explanation:
given,
radius of circle = 1.8 m
mass of the ball = 0.1 Kg
linear speed of the ball = 27 m/s
angular velocity of orbit = ?
ω is the angular speed of the circle
the angular velocity of the orbit is
