Answer:
C is the correct answer
Explanation:
I got it right on my test
Avogadro's number is equal to 6.02 E 23
Thie means we have 6.02 E 23 marshmallows.
Assuming each marshmallow to be a small cylinder we can calculate the area of its base
Area circumference = pi*r² = pi * (0.635/2)² = 0.317 cm²
So, 6.02 E 23 marshmallows * 0.317 cm² cover a total area of
Area covered = 1.908 E 23 cm² = 1.908 E 13 km²
<span>The land area of california is 1.560 E 5 mi</span>² = 4.04 E 5 km²
If we divide the Areas >>>>
1.908 E 13 km² / 4.04 E 5 km² = 47. 227 E 6 (This is the number of times the area of California could be filled with those marshmallows)
Now for the height, we multiply this number times the height of each marshmallow
47. 227 E 6 * 2.54 cm = 119.96 E 6 cm = 1199.6 km above the surface
Answer:
The flux of the electric field is 677.6 Nm²/C
Explanation:
Given that,
Area = 18 cm²
Charge = 6.0 nC
We need to calculate the flux of the electric field
Using Gauss's law
Where, q = charge
=permittivity of free space
Put the value into the formula
Hence, The flux of the electric field is 677.6 Nm²/C.
