Answer:
Gravitational force between two bodies depends on:
1. Masses of the two bodies. The greater an object's mass, the greater its gravitational force.
2. Distance of separation between them. The smaller the distance greater is the gravitational force.

What makes the results of a scientific experiment accurate? (5 points)
Answer:
A measurement is reliable if you repeat it and get the same or a similar answer over and over again, and an experiment is reliable if it gives the same result when you repeat the entire experiment.
Explanation:
Answer: when you repeat it and get the same results
Explanation:
When a scientist repeats an experiment with a different group of people or a different batch of the same chemicals and gets very similar results then those results are said to be reliable. Reliability is measured by a percentage – if you get exactly the same results every time then they are 100% reliable.

What is role of force on the speed of moving object?
Explanation:
this is the ans hope it works
Answer:
Forces make things speed up (or accelerate). When a force pushes or pulls the object, the object will move in the direction of the force. The bigger the force, and the lighter the object, the greater the acceleration.
Explanation:
The action from a force can cause an object to move or speed up (accelerate), to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it can be said that a force on an object results in the acceleration of an object.
A simple mathematical relationship exists between the mass of an object (m), the net force on the object (f) and its acceleration (a). The acceleration of an object is directly proportional to the net force and indirectly proportional to the object’s mass (a = f/m).
Why is diffraction used in soil profiles?
Answer:X-ray diffraction (XRD) is the technique most heavily relied on in soil mineralogical analysis. X-ray diffraction is a technique that provides detailed information about the atomic structure of crystalline substances. It is a powerful tool in the identification of minerals in rocks and soils.
Explanation:
XRD is used to identify the minerals composing clay-rich, hydrothermally altered rocks that occur on several Cascade volcanoes. Such rocks are believed to play an important role in the generation of large landslides and mudflows. XRD is used to analyze saline minerals, including borates.

How do the nuclei of covalently bonded atoms help keep the bond together?
Neutral particles in the nucleus provide enough mass that the force of gravity holds the atoms together.
Neutral particles in the nucleus can become positive or negative in order to balance the charges.
Positive particles in the nucleus change into negative particles that enter electron shells.
Positive particles in the nucleus are attracted to shared electrons, so the atoms stay close together.

How much gravitational energy does a 65 kg skydiver have 650 m up in the sky?
Answer:
G.P.E = 414050 Joules or 414.05 Kilojoules
Explanation:
Given the following data;
Mass = 65 kg
Height = 650 m
We know that acceleration due to gravity is equal to 9.8m/s²
To find the gravitational potential energy;
Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.
Mathematically, gravitational potential energy is given by the formula;
[tex] G.P.E = mgh[/tex]
Where;
G.P.E represents potential energy measured in Joules.m represents the mass of an object. g represents acceleration due to gravity measured in meters per seconds square. h represents the height measured in meters.Substituting into the equation, we have;
[tex] G.P.E = 65 * 9.8 * 650 [/tex]
[tex] G.P.E = 414050 [/tex]
G.P.E = 414050 Joules or 414.05 Kilojoules.
An object with a mass of 1298 kg is accelerating at a rate of 17 m/s² when a net force is applied to it. What is the magnitude of the net force that is acting on the object?
Answer:
Explanation:
This is a simple F = ma equation. We have the mass and we have the acceleration, so
F = 1298(17) and
F = 22066 which rounds correctly to
F = 22000N
The magnitude of the net force of object with a mass of 1298 kg is accelerating at a rate of 17 m/s² is 22066N
HOW TO CALCULATE NET FORCE:
The net force of a body can be calculated by multiplying the mass of the body by its acceleration. That is;Force (N) = mass (kg) × acceleration (m/s²)According to this question, an object with a mass of 1298 kg is accelerating at a rate of 17 m/s². The net force can be calculated as follows:F = 1298Kg × 17m/s²F = 22066NTherefore, the magnitude of the net force of object with a mass of 1298 kg is accelerating at a rate of 17 m/s² is 22066N.Learn more at: https://brainly.com/question/23245710?referrer=searchResults

three resistors of 20. ohms, 30. ohms, and 60. ohms, respectively, are connected in series with a battery. a current of 2.0 amperes will flow through this circuit when the potential difference of the battery is a. 20.V b. 220 V c. 110 V d. 10.V.
Answer:
220 V
Explanation:
[tex]r_{1} = 20 ohm\\r_{2} = 30ohm\\r_{3} = 60ohm[/tex]
As the resistors are connected in series,
[tex]R_{eq} = r_{1} +r_{2} +r_{3}[/tex]
= 20 + 30 + 60
= 110 ohms
V = IR
= 2 * 110
= 220 V

Answer: 75 N
Because we're finding the force, we need to use F = ma. M (Mass) = 25 and A (Acceleration) = 3. Multiply 25(3) to get 75. So, you're answer should be 75 N.

An astronaut wandering the solar system encounters a 726 kg steel block resting
on a surface where (meau) s = 0.650 and k = 0.400. An attempt by the astronaut to set
the steel block in motion across the surface requires a force of 4930 N. On
which planet is this astronaut wandering? Support your answer with calculations.
Answer:
Therefore the planet is Saturn .
Explanation:
Let acceleration due to gravity be g .
weight on the planet = 726 g
Frictional force = μs mg
= .65 x 726 x g
This force is equal to 4930 N .
.65 x 726 x g = 4930 N .
g = 10.44 .
Therefore the planet is Saturn .

Answer:
Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both.

Explanation:
Answer:
B
Explanation:
In contrast to other fish, who have bladders filled with gas, sharks have a liver filled with low-density oil that is similar to vegetable oil. This oil is lighter than water and tends to rise to the top of the water if not contained but because it is in the sharks liver its contained therefor the shark floats!

Answer:
In this section, we elaborate and extend the result we derived in Potential Energy of a System, where we re-wrote the work-energy theorem in terms of the change in the kinetic and potential energies of a particle. This will lead us to a discussion of the important principle of the conservation of mechanical energy. As you continue to examine other topics in physics, in later chapters of this book, you will see how this conservation law is generalized to encompass other types of energy and energy transfers. The last section of this chapter provides a preview.
The terms ‘conserved quantity’ and ‘conservation law’ have specific, scientific meanings in physics, which are different from the everyday meanings associated with the use of these words. (The same comment is also true about the scientific and everyday uses of the word ‘work.’) In everyday usage, you could conserve water by not using it, or by using less of it, or by re-using it. Water is composed of molecules consisting of two atoms of hydrogen and one of oxygen. Bring these atoms together to form a molecule and you create water; dissociate the atoms in such a molecule and you destroy water. However, in scientific usage, a conserved quantity for a system stays constant, changes by a definite amount that is transferred to other systems, and/or is converted into other forms of that quantity. A conserved quantity, in the scientific sense, can be transformed, but not strictly created or destroyed. Thus, there is no physical law of conservation of water.
Systems with a Single Particle or Object
We first consider a system with a single particle or object. Returning to our development of (Figure), recall that we first separated all the forces acting on a particle into conservative and non-conservative types, and wrote the work done by each type of force as a separate term in the work-energy theorem. We then replaced the work done by the conservative forces by the change in the potential energy of the particle, combining it with the change in the particle’s kinetic energy to get (Figure). Now, we write this equation without the middle step and define the sum of the kinetic and potential energies, K+U=E; to be the mechanical energy of the particle
