Answer:
e)
Explanation:
In an RC series circuit, at any time, the sum of the voltages through the resistor and the capacitor must be constant and equal to the voltage of the DC voltage source, in order to be compliant with KVL.
At= 0, as the voltage through the capacitor can't change instantaneously, all the voltage appears through the resistor, which means that a current flows, that begins to charge the capacitor, up to a point that the voltage through the capacitor is exactly equal to the DC voltage, so no current flows in the circuit anymore, and the charge in the capacitor reaches to its maximum value.
No one can really tell exactly how old the universe is. However, scientists have attempted to estimate the time by using the concept of Doppler effect which depends on the frequency of the stars and their relative velocities. From literature, the universe is about 13.82 billion years old. Thus, the age of the universe is 13.82×10⁹ times longer than a year.
I believe the answer is #4. u can always ask google if u believe that's the wrong answer :)
I beleive that the answer is B.
As it stands now, that statement is false.
There are two ways to make the statement true:
#1). Exchange the places of the words "Opposite" and "like".
#2). Exchange the places of the words "repel" and "attract".
Either ONE of these changes will make the statement true.
Doing BOTH of these changes will leave it false.
