When a parallel-plate capacitor is connected to a battery: a ___ is stored on one plate, and a ____ is stored on the other.
1 answer:
Answer:
a.) negative charge, positive charge
Explanation:
In order to solve this problem, we will need to see the image that can be seen in the attached image.
The point a has a higher potential than point B of the resistance R as the current flows from a to b.
The positive plate of capacitor b has higher potential than the negative plate c.
Once the capacitor has been charged to the nominal value, it will have the same potential of the battery, its terminals will open interrupting the flow of current. But keeping the potential or voltage differential through its points. This will allow the capacitor to work as a battery while discharging.

Answer:
The speed of the ambulance is 4.30 m/s
Explanation:
Given:
Frequency of the ambulance, f = 1790 Hz
Frequency at the cyclist, f' = 1780 Hz
Speed of the cyclist, v₀ = 2.36 m/s
let the velocity of the ambulance be 'vₓ'
Now,
the Doppler effect is given as:
where, v is the speed of sound
since the ambulance is moving towards the cyclist. thus, the sign will be positive
thus,
on substituting the values, we get
or
vₓ = 4.30 m/s
Hence, <u>the speed of the ambulance is 4.30 m/s</u>
