Answer:
306500 N/C
Explanation:
The magnitude of an electric field around a single charge is calculated with this equation:
With ε0 = 8.85*10^-12 C^2/(N*m^2)
Then:
E(0.89) = 306500 N/C
The answer is B. darker; cooler
the dark spots give off less energy then the rest of the sun.
Hope this helps
I think the North Pole
If I understand this correctly
Answer:
Explanation:
dU= dq+w
dU is change in internal energy of the system
dq is the amount heat added or released by the system which be positive or negative respectivelý
And w is the amount of work done by the system or on the system which will be positive or negative respectively.
Hence,
dU= 250+80= 330 J
The change will be positive
Answer:
+5m/s
Explanation:
When doing the math we figure out that e is going to be slowing down at -4m/s² for 5 seconds. In total he is slowing down -20m/s which we take from the total speed of +25m/s to get his current new speed.
