Answer:
Yes
Explanation:
The speed of light when it travels through glass, diamond, etc, the light travels at different speed from the speed of light. Speed of the light in material is related to the index of refraction.
The change in speed which occurs when the light passes from one medium to the another is responsible for bending of the light which is called as refraction.
<u>When the light goes into a medium with the higher index of the refraction, light bends towards normal. Conversely, if the light traveling goes from higher refractive index to lower refractive index, it will bend away from the normal.
</u>
<u>Hence, the refraction is different in both the scenario.</u>
Answer:
100 J
Explanation:
From the question, The work done by the forces in moving the box is given as
W = FxdcosФ+Fydcosα................... Equation 1
Where W = Work done, Fx = force acting parallel to the floor, d = distance moved by the box, Ф = angle the parallel force makes with the floor, Fy = force acting perpendicular to the floor, α = angle the perpendicular force make with the floor.
Give: Fx = 10 N, d = 20 m, Fy = 5 N, Ф = 0°, α = 90°
Substitute into equation 1
W = 10×10×cos0°+5×20×cos90°
W = 10×10×1+0
W = 100 J.
Note: The work done by the perpendicular force is zero
Hence the work done = 100 J
Answer:
a)
b)S= 46.4 cm
Explanation:
Given that
Velocity = 16 Km/s
V= 16,000 m/s
E= 27 mV/m
E=0.027 V/m
d= 22.5 cm
d= 0.225 m
a)
lets time taken by electron is t
d = V x t
0.225 = 16,000 t
b)
We know that
F = m a = E q ------------1
Mass of electron ,m
Charge on electron
So now by putting the values in equation 1
Here initial velocity u= 0 m/s
S=0.464 m
S= 46.4 cm
S is the deflection of electron.
V=v0+at=38m/s;
v^2=v0^2+2ad=>d=(v^2-v0^2)/2a=544/4=68m
