Answers

Answer 1

Answer: The earth-moon relationship is unique in many ways. It is the largest moon in the solar system relative to its host planet. The relative size between theearth and moon are so close, some refer to it as a binary planet system. As it is simply a a relationship between a planet and its moon, the system is called a binary system.

Answer 2

Answer:

The relative size of earth and moon are a little bit of close in astronomical world.One can find unique relationship between two planetary systems i.e the earth and moon.

In astrophysics the term binary planet system refers to two planets.Here both the planets are of planetary masses.Two planetary bodies will be considered as the binary system if their sizes are proportional to each other and comparable.

Moon is the one satellite in the entire solar system which is larger than other satellites.The weight of the earth is 81 times more than the weight of earth and it is just 384000 km away from earth .Ideally it can not be considered as binary planet system.But it is considered as a binary planet system as their relative size are so close.

Hence the answer of this question is binary planet system.

Why is there less air pressure at higher altitudes?Air at higher altitudes doesn't have as much air weighing down on it from above.Air at higher altitudes is cooler and less turbulent.The molecules in the air lose mass and are less effected by gravity, significantly lowering their weightThe warmer, lighter air rises bringing cooler heaver air to low altitudes.
When the mass of an object increases, the force of gravityincreases.decreases.remains the same.becomes irregular.

What kind of energy involves the flow of positive charges?

Answers

Answer:

Electrical energy

Explanation:

Electrical energy is the form of energy that results from the existence of an electric current, that is, a flow of electrical charges, through a metallic conductor cable as a result of the potential difference that a generator is applying at its ends.

Electrical would be the energy that involves the flow of positive charges.

At what distance of separation, r, must two 3.20 x 10-9 Coulomb charges be positioned in order for the repulsive force between them to be 83.4 N?

Answers

F = q₁*q₂* C / r²

F =83.4
q₁ = q₂ = 3.2 * 10⁻⁹
C couloumb constant 8.9 * 10⁹

solve for r

I'm not 100% sure but I think the answer is 60.4, because you multiply 3.20 by 10, to get 32 - 9 = 23, then subtract 23 from 83.4. Hope this helps you, and good luck!!!

The two forces in each pair may have different physical origins (for instance, one of the forces could be due to gravity, and its pair force could be due to friction or electric charge). a) True
b) False

Answers

Answer:

b)False

Explanation:

This is the false statement .The two forces in each pair could not have different physical origins.

The two pair of forces have same origin.It can not be possible that one is electric force and other one is gravity force or friction force.

We know that magnitude of electric force is much smaller than the friction force .So they can not be in pair form.

Answer is b) False
