-- The mass of the sun never increases.
-- It does decrease, but not nearly enough to have any noticeable
effect on the orbital motion of the Earth, or any other planet.
-- When Earth is closer to the sun, it moves faster in its orbit.
-- When Earth is farther from the sun, it moves slower in its orbit.
-- The result is that the line from the sun to the Earth always covers
the same amount of area in the same length of time.
-- Johannes Kepler noticed this, and it's his Second Law of planetary motion.
-- Newton showed that if his equations for gravity and motion are correct,
then planets MUST behave this way.
If two forces act on an object in the same direction, the net force is equal to the sum of the two forces
Answer:
60 Amperes
Explanation:
current is the main factor, so current is measured in Amperes
Answer:
Dynamic equilibrium is when the products and the reactants are forming at the same rate. This means that the backward and forward reaction rates are equal.
I hope this helps.
Answer:
The deformation in the pole due to force is 0.70 mm.
Explanation:
Given that,
Height = 20.0 m
Diameter = 4.00 cm
Force = 1100 N
We need to calculate the area
Using formula of area
We need to calculate the deformation
Using formula of deformation
Where, s = shear modulus
F = force
l = length
A = area
Put the value into the formula
Hence, The deformation in the pole due to force is 0.70 mm.
