a. is wrong because that is called magnetic force.
b. gravitational force
c. is an electrical force
Answer:
No.
Explanation:
We shall solve this problem by calculating the resolving power of eye for given wavelength
Resolving Power of eye = \frac{1.22\lambda }{D}
Where λ is wave length of light and D is diameter of eye.
λ is 600 nm and D is 3.5 mm . Put these values in the given formula
Resolving Power = \frac{1.22\times 600\times 10^{-9} }{3.5\times 10^{-3}}\\
=209.14 \times 10^{-6}radian
From the formula
Φ = \frac{L}{D}[/tex]
Where Ф is resolving power . If L be distance between two points that can be resolved at distance D. D is 6 km or 6000 m .
209.14 \times 10^{-6}=\frac{L}{6000}\\
L= 1.254 m
So minimum distance that can be resolved is 1.254 m.
Answer:
c
Explanation:
Mineral water, water, and salt water are all liquid solutions, while oxygen is a gas. Gases are less dense than liquids.
The answer to the question asked above is vertical acceleration is the acceleration of a body in a vertical path either up or down, while lateral acceleration is the acceleration of body in a side manner either left of right.
