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.
Answers
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 .

John's mass is 55kg when he is standing on the edge of a diving
board 24m high. a. Find his mechanical energy.
What is it?
Answers
Answer:
E = 12.9 kJ
Explanation:
Given that,
Mass of John, m = 55 kg
It is standing on the edge of a diving board which is at a height of 24 m.
We need to find his mechanical energy. The mechanical energy of John is equal to its potential energy such that,
E = mgh
E = 55 kg × 9.8 m/s² × 24
E = 12936 J
or
E = 12.9 kJ
So, his mechanical energy is equal to 12.9 kJ.

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.
Answers
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

B
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!

what produces magnetic fields
Answers
Answer:
B is the answer
Explanation:
Magnetic fields are produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin.
Magnetic fields are produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin. As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field.

Answers
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 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?
Answers
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

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.

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 much gravitational energy does a 65 kg skydiver have 650 m up in the sky?
Answers
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.

Answers
Answer:
We will have infinite solutions to the system of linear equations.
Explanation:
Well, when we have two lines with the same slopes and the same y-interception, both of them are overlapped, so we will have infinite solutions to the system of linear equations.

What is role of force on the speed of moving object?
Answers
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).
What makes the results of a scientific experiment accurate? (5 points)
Answers
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.
