Answer: B. a stream of particles
The light is said to travel in a straight line and casts a shadow therefore, Isaac Newton formulated a hypothesis stating that lights is a stream of particles. This theory is later called the Corpuscular theory of light.
Answer:
The current can be controlled by modifying the resistance value
Explanation:
The current can be controlled by modifying the resistance value, usually a variable resistance device called potentiometer is used. This can be observed mathematically using the ohm law which is defined as voltage equal to the current product by resistance.
V = I*R
where:
I = current [amp]
R = resistance [ohm]
V = voltage [volt]
We can see that if we reduce the resistance the current will be increased
I = v / R
And if we amplify the resistance (R) the current will be diminished
When the current is time-dependent, the circuit has a
capacitor. A capacitor could be used to store energy. As you use it up, the
energy depletes. This is why it is time-dependent. The answer is 12 seconds. I
hope I answered your question. Have a good day and thanks.
Frequency multiplied by the wavelength
6*2 = 12
