b. the masses of the objects and the distance between them.
c. the weight of the objects and their speeds.
d. the masses of the objects and their weights.
The correct answer to the question is : B) The masses of the objects and the distance between them.
EXPLANATION :
Before going to answer this question, first we have to understand Newton's law of gravitation.
As per Newton's law of gravitation, everybody in the universe attracts every other body with a force called gravitational force or force of gravity which is directly proportional to the product of masses of the two bodies, and inversely proportional to the square of separation distance between them.
Let us consider two bodies of masses M and M' which are separated by a distance R.
The gravitational force acting between them is calculated as -
Gravitational force
Here, G is known as universal gravitational force constant.
From above, we see that force of gravity depends on the masses of the objects and the distance between them.
(k = 9.0 × 109 newton·meters2/coulomb2)
A 2.4 × 10-2 coulombs
B 4.6 × 10-11 coulombs
C 5.2 × 10-11 coulombs
D 7.2 × 10-8 coulombs
Option B 4.6 × 10-11 coulombs.
Fe = q1q2k/r2
q1 = fer2/q2k
q1 = 1.6 x 10-11
Newton Per Coulomb ( N/C) is a unit in the category of Electric field strength. It is also known as newtons/coulomb.

b. mass
c. energy
d. volume
The best description of the 'ability to do work' is 'energy'. This concept explains the capacity an object has to perform action and can be illustrated by different forms of energy like potential or kinetic.
The ability to do work is best described by c. energy. In physics, energy is the capacity to do work. Objects can hold this ability until it's converted into action, like lifting a box or lighting a bulb. This concept applies to various forms of energy such as potential energy, kinetic energy, and more. For example, a boulder at the top of a hill has potential energy due to its position, which can be converted into kinetic energy (work) as it rolls down.
#SPJ6
The space around a charge or a pole in which a force is experienced is called a magnetic field. And a cluster of aligned magnetic atoms is a magnetic domain. When the clustered regions are aligned with one another, they form a magnet.

Answer:
3
Explanation:
Because the atomic number of oxygen is 8 therefore it will be +8
2) 1.0 x 10^3 N
3) 1.5 x 10^3 N
4) 5.0 x 10^5 N
Answer:
2) 1.0 x 10^3 N
Explanation:
As a 5.0 x 10^2 newton basketball player jumps from the floor up toward the basket, the magnitude of the force of her feet on the floor is 1.0 x 10^3 newtons. As she jumps, the magnitude of the force of the floor on her feet is
1) 5.0 x 10^2 N
2) 1.0 x 10^3 N
3) 1.5 x 10^3 N
4) 5.0 x 10^5 N
The answer is B , because from newton's third law of motion which states that action and reaction are equal and opposite.
so the reaction of the floor on her leg will be equal to the the magnitude of her feet on the floor, this will hold if the floor does not collapse.
