That was Johannes Kepler.
He couldn't say why that should happen. But he was able to show that
if we <em><u>assume</u></em> the the sun is in the center of the solar system, and <em><u>assume</u></em>
that the planets revolve around the sun in elliptical orbits, and <em><u>assume</u></em> that
the farther a planet is from the sun the longer it takes to orbit the sun, then
<em>that matches everything that we see the planets actually doing in the sky</em>.
Then Isaac Newton came along, and wrote down a short, simple formula
for the force of gravity. And then he showed that <u>IF</u> his formula for gravity
is correct, then the planets MUST do everything that we see them actually
doing in the sky, and they MUST behave according to Kepler's laws.

The answer is B because there is a total of 10N to the right and 5 to the left, 10-5=5
Answer:
V = 31.62 m V
Explanation:
Given,
Voltage across thick membrane = ?
Thickness of the membrane, d = 5.5 n m
Electric field = 5.75 M V/m
we know
V = E d
V = 5.75 x 10⁶ x 5.5 x 10⁻⁹
V = 31.62 x 10⁻³ V
V = 31.62 m V
Hence, The Voltage across the membrane is equal to 31.62 m V.
