Answer:
Gravity is the force of attraction between two objects; it is dependent upon the mass of the objects and the distance between the objects.
Explanation:
Gravity is defined as the force of attraction between two objects. It depends on the masses of objects and the distance between them. The gravitational force between two bodies is given by the universal law of gravitation. According to this law, the force of gravity is :

Where
G is the universal gravitational constant
m₁ and m₂ are masses of two bodies
d is the distance between two bodies
Hence, the correct statement that describes gravity is (b)
Answer:

Explanation:
The force of friction between the quails feet and the ground is:







So the coefficient of static is solve



Answer:

Explanation:
magnetic flux is the count of magnetic field lines passing through a given loop or area
As we know that magnetic flux is given by the formula

here we also know that magnetic field B and plane of the coil is perpendicular in initial position
So the area vector is always perpendicular to the plane of the coil
so the angle between magnetic field and area vector is parallel to each other and this angle would be zero
so magnetic flux of the coil initially we have

Here are the answers to the question. Make sure to give a valid reason, please.
A. the sum of the protons and neutrons in one atom of the element.
B. a ratio based on the mass of a carbon-12 atom.
C. a weighted average of the masses of an element's isotopes.
D. twice the number of protons in one atom of the element.
