4. a poor insulator
If rest other things are kept constant or unchanged then a good conductor can be termed as a poor insulator.
C: reflected
because the sun shines on the water when u look into the water u can see the sun
Answer:
gamma rays < X-ray < ultraviolet ray < visible light < infrared < radio wave
Explanation:
given light form,
A) radio waves,B) infrared,C) visible light,D) ultraviolet,E) X-rays,F) gamma rays
we know,
wavelength of radio wave = 10000 Km
wavelength of infrared = 700 nanometers (nm) to 1 millimeter (mm)
wavelength of visible light = 380 to 740 nm
wavelength of ultraviolet ray = 10 nm to 400 nm
wavelength of X-ray = 0.01 to 10 nm
wavelength of gamma rays = 100 picometer
so, the order of rays.
gamma rays < X-ray < ultraviolet ray < visible light < infrared < radio wave
Answer:
See the explanation below.
Explanation:
Indeed this is a serial circuit, in order to calculate the different questions, we must calculate the current of the circuit. The total resistance of the circuit can be calculated by means of an algebraic summation.
Then using ohm's law,we can calculate the current.
Rt = 2 + 4 + 6 = 12 [ohm]
The current
I = V / Rt
I = 12 / 12
I = 1 [amp]
Therefore the voltage in each resistance will be:
V1 = 2 * 1 = 2 [V]
V2 = 4 * 1 = 4 [V]
V3 = 6 * 1 = 6 [V]
The total voltage will be:
V = V1 + V2 + V3 = 12 [V]
The power can be calculated by multiplying the voltage by the total current.
P = V * I
P = 12 * 1
P = 12 [W]
