Answer:
A is a gas becasue it contracts and the containers change.
<h2>Answer:</h2><h3>(A) the positively charged surface increases and the energy stored in the capacitor increases.</h3>
When charging a capacitor transferring charge from one surface to the other, the first surface becomes negatively charged while the second surface becomes positively charged. As you transfer the charge, the voltage of the positively charged surface increases and the energy stored in the capacitor also increases. We can solve this by the definition of <em>capacitance</em><em> </em>that is <em>a measure of the ability of a capacitor to store energy. </em>For any capacitor, the capacitance is a constant defined as:
![C=\frac{Q}{V_{ab}}](https://tex.z-dn.net/?f=C%3D%5Cfrac%7BQ%7D%7BV_%7Bab%7D%7D)
To maintain
constant, if Q increases V also increases.
On the other hand, the potential energy
can be expressed as:
![U=\frac{Q^{2}}{2C}](https://tex.z-dn.net/?f=U%3D%5Cfrac%7BQ%5E%7B2%7D%7D%7B2C%7D)
In conclusion, as Q increases the potential energy also increases.
Answer:
you add 67 to 1+1 is this clear also chicken nuggets
Acceleration = (change in speed)/(time for the change)
Change in speed = (end speed) - (start speed)
Change in speed = (10 m/s) - (20 m/s) = -10 m/s
Time for the change = 5.00 seconds
Acceleration = (-10 m/s) / (5 sec)
<em>Acceleration = -2 m/s²</em>
That's choice-A .
Answer:
50.4÷1.18= 42.7m/s as speed is equal to the distance over the time taken
