Answer:
Explanation: In DC circuit, the current will flow for a short time, which is required to charge the capacitor. Once you switch it on, it spikes and the gradually decreases to almost zero (0) as the capacitor becomes fully charged.
In an AC circuit, the circuit acts as if the current is flowing throw the plates whereas is not actually flowing. The circuit acts like the AC is flowing through the capacitor.
Answer:
Wavelenght is 4.53x10^-7m
Explanation:
Detailed explanation and calculation is shown in the image below
That is called fully constructive interference.
Answer:
In the reaction you would have 15.0 mols of Y and X.
Explanation:
The stoichiometric coefficents for X and Y are 1 and 2 respectively, if you start the reaction with 10.0 moles of Y you would need 5.0 moles of X in order to achieve a complete reaction so you will have 15.0 total moles in the reaction, assuming no mass loss and no nuclear reactions.

Answer:</h2><h3><u>QUESTION①)</u></h3>
<em>✔ First step : calculate the kinetic energy that this car requires to reach 95 km/h</em>
95/ 3,6 ≈ 26,4 m/s
<em>Ec = ½ m x V² </em>
With Ec in J; m in kg; and V in m/s
- Ec = ½ 1750 x 26,4²
- Ec ≈ 610 000 J
<em>✔ Knowing that the car has a p power of 215,000 W, so :
</em>
T = E/P
- T = 610 000/215 000
- T ≈ 2.8 s
<h3>
The car takes 2.8 s to reach 95 km/h </h3>
<h3><u>QUESTION②)</u></h3>
N = 2,8/6,5 x 100 = 43.07
<h3>The car efficiency is 43 % </h3>
