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)

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

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.
Hi!!I need sum help with this bc my teacher told me it had to be more specific!
I will award brainiest for the beat answer!Thank you!
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.

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.

The results suggested that the diameter of the nucleus of a gold
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.
Balok diam diatas bidang miring pada sudut kemiringan 40° balok mulai bergerak,tentukan koefisien gesek statis antara balok dan bidang miring
Answer:
0.84
Explanation:
m = Massa balok
g = Percepatan gravitasi
[tex]\theta[/tex] = Sudut kemiringan
[tex]\mu[/tex] = Koefisien gesekan statik antara balok dan bidang miring
Gaya balok karena beratnya diberikan oleh
[tex]F=mg\sin\theta[/tex]
Gaya gesekan diberikan oleh
[tex]f=\mu mg\cos\theta[/tex]
Kondisi dimana balok mulai bergerak adalah ketika gaya balok akibat beratnya sama dengan gaya gesek pada balok.
[tex]mg\sin\theta=\mu mg\cos\theta\\\Rightarrow \mu=\dfrac{mg\sin\theta}{mg\cos\theta}\\\Rightarrow \mu=\tan\theta\\\Rightarrow \mu=\tan40^{\circ}\\\Rightarrow \mu=0.84[/tex]
Koefisien gesekan statik antara balok dan bidang miring adalah 0.84.

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

displacement
True
False
Answer:
true..........................
Speed and velocity use the same formula for calculations. However, an object can have a different average speed and average velocity because of displacement. This is true statement.
What are velocity and speed?As a vector quantity with both magnitude and direction, velocity has both. This term refers to the speed at which an object is moving or shifting positions.
Since speed is a scalar quantity, it lacks direction. It indicates the rate of a moving thing. When a particle's speed is high, it indicates that it is travelling quickly, and when it is low, it indicates that it is going slowly.
The displacement of a body during a period of time divided by the passage of time yields the average velocity of the body during that period.
The distance travelled by a body in a given amount of time, divided by the amount of time, is the body's average speed.
