Yes, yea, yep, you don't make much sense.
Answer:
The angular separation equals 
Explanation:
We have according to Snell's law


Using this equation for both the colors separately we have

Similarly for violet light we have

Thus the angular separation becomes

Charging a balloon and rubbing it on wool is an example of static electricity.

Answer:
The voltage drop across the bulb is 115 V
Explanation:
The voltage drop equation is given by:

Where:
ΔW is the total work done (4.6kJ)
Δq is the total charge
We need to use the definition of electric current to find Δq

Where:
I is the current (2 A)
Δt is the time (20 s)


Then, we can put this value of charge in the voltage equation.

Therefore, the voltage drop across the bulb is 115 V.
I hope it helps you!
