He needs to measure when he draws the Simpson characters to make sure they are the same time each time he draws them
Answer: 3.12 * 10^12 F ( 3.12 pF)
Explanation: To calculate this capacitor of two hollow, coaxial, iron cylinders, we have to determine the potental differente between them and afeter that to use C=Q/ΔV
The electric field in th eregion rinner<r<router
By using the Gaussian law
∫E*ds=Q inside/εo
E*2*π*rinner^2*L= Q /εo
E=Q/(2*π*εo*r^2)
[Vab]=\int\limits^a_b {E} \, dr
where a and b are the inner and outer radii.
Then we have:
ΔV= 2*k*(Q/L)* ln (b/a)
replacing the values and using that C=Q/ΔV
we have:
C= L/(2*k*ln(b/a)=0.17/(2*9*10^9*3.023)=3.12 pF
Answer:
289.1kg
Explanation:
because W=M*G, and M=W/G, so 2891N/10m/s²=289.1kg
The answer is AREA .............
Displacement is defined as the net distance traveled through the entire trip. That is to say, if you compared where you are at the end of the walk to where you were at the start, the displacement is the distance between those two points.
Distance doesn't compare the two end points. It just counts the total distance you've walked throughout your trip.
Lisa walks once around the block. She starts and ends at the same place. Her displacement is therefore 0 m.
But she has walked 1 mile throughout the trip. Her distance walked is therefore 1 mile.
