C wavelength due to the fact the a frequency does not have an x but a y
Answer:
D = 0.2374 m
Explanation:
let D be the diameter of the image of mars, f be the focal length of the telescope mirror and β be the spatial resolution.
β = 6794×10^3/(5.58×10^7) = 0.1217562724
then:
The diameter of the telescope mirror is given by:
D = f×β
= (1.95)×(0.1217562724)
= 0.2374 m
Therefore, the diameter of the image of mars is 0.2374 m.
Explanation:
It is given that,
Radius of the front sprockets, 
Radius of the rear sprockets, 
The angular speed of the front sprocket is 12.3 rad/s, 
(a) Linear speed of the front sprockets, 
Linear speed of the rear sprockets, 
(b) Let 
is the centripetal acceleration of the chain as it passes around the rear sprocket.
`Hence, this is the required solution.
Answer: C
Explanation:
A bird flying in the air is 3D motion as the bird move up, down, right, left all the possible direction. A leaf falling from a tree is also a 3D motion because a leaf never fall in absolute vertical manner. A lady bug crawling on a soccer ball also 3D. If lady bug crawling on a plane like floor then it is 2D but now lady bug crawling on soccer ball which is in spherical shape so it is also 3D motion. Only train travelling along a track is 2D because train cannot move up and down and the track of train is in a plane. So it is 2D motion.
