the diameter of the atom.
The diameter of a gold atom is 0.18 nm
Calculate the diameter of a gold nucleus in nm.
Answer:
The diameter of the gold nucleus is 3.0 × 10⁻⁵ nm
Explanation:
The given parameter of the gold atom are;
The diameter of the gold atom = 1/6,000 × The diameter of the atom
The diameter of a gold atom = 0.18 nm
The diameter of the gold nucleus, [tex]d_{Gold -nucleus}[/tex] = 1/6,000 × 0.18 nm = 0.00003 nm
∴ The diameter of the gold nucleus, [tex]d_{Gold -nucleus}[/tex] = 0.00003 nm = 3.0 × 10⁻⁵ nm.

Question:
Use your knowledge of waves in the graph shown to determine the frequency of wave C. What does it tell you about the speed of the wave?
"Frequency" means how often something happens. When you say how many times it happens every SECOND, you can call the number Hertz, or Hz.
In the graph, there are 10 vibrations in 10 seconds, 20 of them in 20 seconds, and 30 in 30 seconds. This should pretty much shout at you "THERE'S ONE VIBRATION EVERY SECOND !". When you realize that, you can say the frequency of the vibration is 1 Hz.
The graph tells us nothing about the speed of the waves. I suspect there's another picture to the question that you didn't include. If the other part shows the wavelength, then we could figure out the speed. But with just what you're showing us, we can't.

A 61.0 kg box is sitting at rest. In order to change the box's state of
motion, Jamie must apply 75.1 Newtons of force on the box. Which of the
following represents a possible value for the force of static friction when
Jamie applied 75.1 Newtons of force on the box? (**hint- you do not need
to do math for this problem) *
A. 71.9 N
B. 75.1 N
C. 85.3 N
D. 133 N
A possible value for the force of static friction when Jamie applied 75.1 Newtons of force on the box is 75.1N. Option B is correct.
For the box sitting on a horizontal surface, the formula for calculating the force on the box along the horizontal based on Newton's law is expressed as;
[tex]\sum F_x=ma_x[/tex]Since the forces acting along the horizontal are the frictional force and moving force, the formula above will become;
[tex]F_m-F_f=ma_x[/tex]Since the body is static, hence [tex]a_x=0m/s^2[/tex], the equation becomes;
[tex]F_m-F_f=m(0)\\F_m-F_f=0\\F_m=F_f[/tex]Given the force Jamie apply on the box to be 75.1Newtons, this shows that the moving force is 75.1N. Hence;
[tex]F_m =F_f=75.1N[/tex]Hence a possible value for the force of static friction when Jamie applied 75.1 Newtons of force on the box is 75.1N

Answer:
The phases occur because the Sun lights different parts of the Moon as the Moon revolves around the Earth. That means the reason we see different phases of the Moon here on Earth is that we only see the parts of the Moon that are being lit up by the Sun.

One advantage that sexual reproduction has over asexual reproduction is the ability to produce genetic diversity. Why is genetic diversity an advantage?
Answer:
Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population

A horse pulls a carriage by applying 450 N of force. Find the traveled distance if the horse did 89 kJ of work.
Answer:
distance = 197.8 m
Explanation:
Use the formula for work as the force times the distance the force was acting on the object.
W = F * d
89000 J = 450 N * d
d = 89000/450 m
d = 197.8 m
A car drives in a circle at 56 km/hr. Which of
the following accurately describes the
motion of the car? The car's -
speed and velocity are both constant.
velocity is constant but speed is changing.
speed is constant but velocity is changing.
speed and velocity are both changing.
Answer:
Speed is constant but velocity is changing
Explanation:
Speed is a scalar quantity, meaning magnitude only. Velocity is a vector quantity, meaning magnitude and direction. If you're moving in a circle at a constant speed, the speed is constant but the direction is constantly changing. Therefore, the speed is constant but velocity changes.
Find the following answer based on the image.
We are given:
Mass of Neptune = 1.03 * 10²⁶ kg
Distance from the center of Neptune (r) = 2.27 * 10⁷
now, computing the value of the acceleration due to gravity (g)
Finding g:
We know the formula:
g = G(mass of planet) / (r)²
g = [6.67 * 10⁻¹¹ * 1.03*10²⁶] / (2.27*10⁷) [since G is 6.67*10⁻¹¹]
g = (6.87 * 10¹⁵) / (5.15 * 10¹⁴)
which can be rewritten as:
g = (6.87 * 10¹⁵ * 10⁻¹⁴) / 5.15
g = (6.87 * 10¹⁵⁻¹⁴) / 5.15
g = (6.87/5.15) * 10
g = 1.34 * 10
g = 13.4 m/s² (approx)
Sugar dissolved in water is an example of?
A. Precipitate
B. Molecule
C. Compound
D. Solution
Answer:
D. Solution
Explanation:
Sugar dissolved in water is an example of solution.
A solution is a homogenous mixture of solutes and solvents.
In a solution the solute particles ae distributed uniformly in the solvents. The solute is the substance and it is the sugar here that is dissolved to make a solution.
The solvent is the water in this instance that helps to dissolve the solute.
Answer:
D. Solution
Explanation:
Dissolving sugar in water is an example of a physical change. Here's why:
A chemical change produces new chemical products. In order for sugar in water to be a chemical change, something new would need to result.

Why is oxygen more chemically reactive than nitrogen?
A. Oxygen needs to gain only 2 electrons to have a full octet, while
nitrogen needs to gain 3.
B. Oxygen needs to gain only 2 electrons to have a full octet, while
nitrogen needs to lose 3.
C. Oxygen needs to lose only 2 electrons to have a full octet, while
nitrogen needs to lose 3.
D. Oxygen needs to lose only 2 electrons to have a full octet, while
nitrogen needs to gain 3.
Oxygen is more chemically reactive than nitrogen because Oxygen needs to gain only 2 electrons to have a full octet, while nitrogen needs to gain 3. The correct option is A.
What are electrons?The electrons are the spinning objects around the nucleus of the atom of the element in an orbit.
Valence electrons are the electrons present in the outermost shell of an atom. They can easily be determined by the number of valence electrons in an atom by looking at the specific group in the periodic table.
The fewer number of electrons in the valance shell, the more reactive is the element.
Oxygen needs to gain only 2 electrons to have a full octet, while nitrogen needs to gain 3.
Thus, Oxygen is more chemically reactive than nitrogen.
Then the correct option is A.
