5c) 300 Degrees is the junction

10b )


ON 08
2d) You can take any 2 piece of information and add 200G to it.
So I'll take 400 and 300
400 + 300 + 200 = 900g
1kg = 10N
1kh = 1000 gram
1000 gram = 10N
900 gram = 9N

5c) Energy = Mass X Specific latent heat
E = Pt
Pt = 40 X 120 (2 minutes)

40 X 120 = (16.3-2.1) x Specific latent heat
4800 = 14.2 X Specific latent heat

Specific latent heat = 4800/14.2 = 338 J/g

6d) Monochromatic light means a light with one wavelength so when it hits at F, many colors would appear such as red to violet.
6e) 90 Degres
6f) Total Internal Reflection

7c) 8 Hz, same value as the one above as diffraction doesn't change frequency of the wave

8c) There is 12J of energy in the circuit for each coulomb of charge

How?

10 B
How?

Light in room - High
Dark in room - Low

Position P - High
Position Q - Low

As it is in use the position is in P so it is HIGH over in P and hence the light is also high

I know the answer but HOW??

I know the answer but HOW??

Voltage level is high when there is light in the room as when there is light - the buzzer will ring.
When there is dark in the room - There is no buzzer so the voltage is low

Similarly when P is connected in the circuit - The room is being used so it is high
In Q it is not being used to the voltage is low
