Can anyone help with this physics question

Answer:

i dont know

Explanation:

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.

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

"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 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;

Since the forces acting along the horizontal are the frictional force and moving force, the formula above will become;

Since the body is static, hence [tex]a_x=0m/s^2[/tex], the equation becomes;

Given the force Jamie apply on the box to be 75.1Newtons, this shows that the moving force is 75.1N. Hence;

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 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.

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.

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.

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 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:

Answer:

C.

Explanation:

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.
