<h2>Answer: decreasing</h2>
An RC circuit is an electrical circuit composed of resistors and capacitors, where the charging time 
of the circuit is proportional to the magnitude of the electrical resistance 
and the capacity 
of the capacitor.
As shown below:
In this context, the electrical resistance is the opposition to the flow of electrons when moving through a conductor.
Therefore:
<h2>When a capacitor is being charged in an RC circuit, the current flowing through a resistor <u>decreases</u>.</h2>
And the correct option is b.
Answer:
1.4 * 10 ^-1 Ω
Explanation:
Hi,
For this question, we gotta use the formula
R = pL/A
p = The resistivity of your material at 20°C
L = length of the wire
A = cross-sectional area
The resistivity of tungsten is 5.60 * 10^-8 at 20°C
By plugging the values, we get:
R = (5.60 * 10^-8)(2.0)/(7.9*10^-7) = 1.4 * 10 ^-1 Ω
Your answer is correct. No problem and Have a nice day
Answer:
a) v = 19,149.6 m/s
b) f = 95%
c) t = 346.5min
Explanation:
First put all values in metric units:
The equation of motion you need is:
where 
is the final velocity, a is acceleration and t is time in hours.
Since the spaceship starts from 0 velocity:
Next, you need to calculate the distances traveled on each interval, considering that both starting and final intervals travel the same distance because the acceleration and time are equal. For this part you need the next motion equation:
solving for first and last interval:
Since the spaceship starts and finish with 0 velocity:
Then the ship traveled 
at constant speed, which means that it traveled:
Which in percentage is 95% of the trip.
to calculate total time you need to calculate the time used during constant speed:
That added to the other interval times:
