Well, if we've been paying attention in class, we already KNOW that the electrostatic force changes as the inverse square of the distance, and the top graph is conveniently labeled "Electrostatic Force".
But if we didn't already know that, we'd have to examine the graphs, and find the one where 'y' changes like 1/x² .
The top graph does that. After 1 unit of time, the force is 350. Double the time to 2 units, and the force should drop to 1/4 of 350 ... sure enough, it's a little less than 90. Double the time again, to 4 units, and it should drop to 1/4 of a little less than 90 ... by golly, it's down below 30.
The first graph is what an inverse square looks like. Now that you've worked out this graph, you'll know an inverse square relationship whenever you see it.
Explanation:
Sky appears blue because of Scattering.Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
Answer:
1.11 x 10^6 m
Explanation:
mass of Pluto, M = 1.1 x 10^22 kg
acceleration due to gravity on Pluto, g = 0.59 m/s²
let R be the radius of the Pluto and G is the universal gravitational constant.
G = 6.67 x 10^-11 Nm²/kg²
use the formula for the acceleration due to gravity
R = 1.11 x 10^6 m
Thus, the radius of the Pluto is 1.11 x 10^6 m.
Both
Explanation: the thing is you will adapt to your environment in order to survive I know this because if you live in a environment where a whole bunch of people get sick, you will get a stronger immune system when you are born.Your genes also come from you family members to. That is why the answer is both. Have a nice day!
Answer:
electrons
Explanation:
The total charge Q is the sum of the charge of the N electrons contained in the sphere:
charge of a electron
We solve to find N:
