Answer:
J=0.211kg.m/s
Explanation:
The impulse-momentum theorem states:
The velocity before the impact is given by:
For the velocity after the impact:
so:
The number of protons
number of neutrons=the mass number- number of protons
14-6=8
Explanation:
3 cause the triangle method of addition are connected to tips of one vector
Answer:
λ = 1.2 x 10⁻⁶ m
Explanation:
Given that,
slit separation, d = 0.050 mm
= 5 x 10⁻⁵ m
Distance between the fringes, D = 5.00 m
distance between the fringes, x = 12.0 cm
= 0.12 m
wavelength of the light = ?
the separation between the fringe is given by
where as n = 1
λ = 1.2 x 10⁻⁶ m
Answer:
Explanation:
Given:
- depth of fish,
- angle of incidence,
- refractive index of water,
<u>Apparent distance from the normal projection at the bottom of entrance at air-water surface to the fish:</u>
<u>Now according to Snell's Law:</u>
<u>Now the actual distance of the fish from the bottom surface at the normal:</u>
<u>Now distance between bullet hole and fish</u>:
