Answer:
C₁ = 3 pF
C₂ = 6 pF
Explanation:
Let the capacitance be C₁ and C₂.
For parallel combination
C₁ +C₂ = 9
For series combination
C₁ X C₂ = 18
( 9-C₂ )X C₂ = 18
C₂²- 9C₂ +18 = 0
C₂ = 6 or 3.
C₁ = 3 or 6.
C₁ = 3 pF
C₂ = 6 pF
Answer:
1000kg
Explanation:
We can use the equation "p=mv"
- p is the momentum in kg m/s
- m is the mass measured in kg
- v is the velocity measured in m/s
If we rearrange the equation to find mass (m), then the equation becomes:
m=p/v
We can substitute in the values of p and v as they are already given in the question.
So, now we just substitute in the values to get our answer.
m=p/v
m=25,000/25
m=1000kg
Changing the tilt of the axis from 23 degrees to 45 degrees would dramatically change the seasons. They would be more extreme. Increasing the tilt angle means a larger section of the earth would experience one season for a longer period. There would be longer and colder winters and likewise hotter and longer summers.
Answer:
They do this because it covers the whole surface which they are cleaning. the cleaner all hold the same charge and repel from each other and cover the whole surface. They want to do this to make sure the item that they cleaning is clean.
how does the electric force between two charged particles change if the distance between them is increased by a factor of 3?
a. it is reduced by a factor of 3
