Answer:
1.94 x 10^-10 m
Explanation:
V = 40 V
The relation for the de broglie wavelength and teh potential difference is given by
λ = 1.94 Angstrom = 1.94 x 10^-10 m
Answer:
Explanation:
The refractive index of the lens is
d = 1.570 dioptres
Therefore, her focal length is
f = 1 / d
f = 1 / 1.570
f = 0.6369 m
f = 63.69cm
The distance between the newspapers and her eyes is 42cm
Distance from her eye to the glasses is 2cm
We want to calculate her near point?
So, the distance between the newspaper and the glass
do = 42 - 2 = 40cm
The distance between the glass and the virtual image formed is given as
di = f•do / (do —f)
di = 63.69 × 40 / (40 — 63.69)
di = 2547.6cm / -23.69
di = —107.54cm
The relation use is obtain from the lens equation and the negative shows that virtual image formed.
The near point from her eye is
107.54 + 2 = 109.54cm
Answer: If one billiard ball hits another, the second will move with the same force as the first.
A child wants to jump to climb a tree (reaction), he must push the ground to propel himself (action).
A man deflates a balloon; the force with which the air comes out causes the balloon to move from one side to the other.
