Answer:
So capacitance is charge divided by voltage and we can multiply both sides by V to solve for Q. So Q—the charge stored in the capacitor—is the capacitance multiplied by the voltage. So it's 180 times 10 to the minus 6 farads times 120 volts which is 0.0216 coulombs.
Explanation:
Because while you collect your gpa you’re gonna be missing out on all the fun experiences you might have a chance to experience but it’s worth it to study and get a good gpa once u get one you’d go to college, graduate and do whatever you want after!!
Answer:
Explanation:
Given
Halley's closest distance from sun is 
Greatest distance is 
Comet's speed at closest approach is 
As there is no external torque so angular momentum of comet about the sun is conserved


where 
This can be written as 
Therefore



I believe the answer is B
The photoelectric effect supports a particle model of electromagnetic radiation as it behaves like an elastic collision between two particles.
<h3>What is Photoelectric effect?</h3>
This is defined as the emission of electrons when electromagnetic radiation, such as light, hits a material.
The energy of a wave increases with an increase in intensity and in photoelectric effect. However intensity has no effect on the energy of electrons emitted which is why it is inadequate to explain the photoelectric effect.
