b) The velocity vector is 2.33 in/s
Explanation:
a) According to the diagram 1 in the attached image:
Also:

If we comparing both sides of the expression:
b) According to the diagram 2 in the attached image:

Comparing both sides of the expression:

Answer:(c)
Explanation:
Charge particle posses a region of influence called a filed i.e. Electric field.
It is a region around the charged particle such that other charge particle experiences force due to this field. The nature of force is decided by the charge on the particle creating an electric field.
For a positive charge, electric field lines emerge out of it, and for a negative charge, it acts as radially inwards.
Answer:
C
Explanation:
momentum = mass ×velocity
A. mv = 200
B. mv = 300
C. mv= 400
D. mv= 200
highest is C.
The power of the lens is 2 diopter means that this lens has a focal length of 1/2 meter.
The focal length = 1 ÷ ( the number of diopters)
If one's glass prescription shows that the power of the lens is 2 diopter it means that the person is far-sighted. It means if a person needs to see something which is quite distant then his eyes need extra lens power to focus on it. Moreover, if there's a sign convention it means '+' indicates a convex lens and '-' concave lens. Also in-camera close up lens are also measured in terms of diopter.
I hope this answer helps.
