Hello I hope you are having a great day :)

Your question: When a light switch is turned on, the light comes on immediately because....

The answer is: the electrons in the wire are instantly "pushed" by a voltage difference making the the light switch on.

Hopefully that helps you :)

A hockey puck, mass of 0.115 kg, moving at 35 m/s strikes a ray thrown on the ice by a fan. The ray has a mass of 0.265 kg. The

We can use conservation of momentum. MaVa + MbVb = (Ma+Mb)Vf.

Plugging in values:
(.115)(35) + (.265)0 = (.380)(Vf)

Now solve for Vf.
Vf= .115*35 / .380 = 10.6 m/s

Two large thin metal plates are parallel and close to each other. On their inner faces, the plates have excess surface charge of

wariber [46]

Answer:

For left = 0 N/C

For right = 0 N/C

At middle = $-7.6836 * 10^{-11} \vec{i}$ N/C

Explanation:

Given data :-

б = $6.8 * 10^{-22}$ C/ m²

Considering the two thin metal plates to be non conducting sheets of charges.

Electric field is given by

$E = \frac{\sigma }{2\varepsilon }$

1) To the left of the plate

$\vec{E}= (\frac{\sigma }{2\varepsilon })(-\vec{i})+ (\frac{\sigma }{2\varepsilon })(\vec{i})$ = 0 N/C.

2) To the right of them.

$\vec{E}= (\frac{\sigma }{2\varepsilon })(-\vec{i})+ (\frac{\sigma }{2\varepsilon })(\vec{i})$ = 0 N/C.

3) Between them.

$\vec{E}= (\frac{\sigma }{2\varepsilon })(-\vec{i})+ (\frac{\sigma }{2\varepsilon })(-\vec{i})$ = $(\frac{\sigma }{\varepsilon })(-\vec{i})$ = $-\frac{6.8 * 10^{-22} }{8.85 * 10 ^{-12} } \vec{i}$ = $-7.6836 * 10^{-11} \vec{i}$ N/C
