By using Newton law of gravitation, the weight of the object when it moves 450 km above the center of the planet is 20N

Given that the weight of an object is 180 N at a distance of 150 km above a planet's center.

F = GMm/[tex]r^{2}[/tex]

F = mg = 180N

r = 150

When it moves 450 km above the center of the planet, G, M and m will be constant. only r will vary.

180 = GMm/[tex]150^{2}[/tex]

Make GMm the subject of the formula

GMm = 180 x 22500

GMm = 4050000

As it moves 450 km above the center of the planet, Its weight will be

F = GMm/[tex]r^{2}[/tex]

Substitute all the values and parameters

F = 4050000/[tex]450^{2}[/tex]

F = 20 N

Therefore, the weight of the object When it moves 450 km above the center of the planet is 20 Newtons

A substance with a pH value of 2.3 would be classified as a strong acid. Option A is correct.

pH stands for "potential hydrogen," and it is a measure of the acidity or basicity (alkalinity) of a solution. The pH scale ranges from 0 to 14, with 7 being neutral (neither acidic nor basic). Solutions with a pH less than 7 are considered acidic, and solutions with a pH greater than 7 are considered basic.

Here,
The pH scale is used to measure the acidity or basicity of a solution. Values on the pH scale range from 0 to 14. Solutions with a pH value less than 7 are considered acidic, and solutions with a pH value greater than 7 are considered basic. The lower the pH value, the more acidic the solution.

A pH value of 2.3 indicates that the solution is strongly acidic, as it is well below the neutral value of 7.

The important thing to remember is that gravity is neither a push nor a pull; what we interpret as a “force” or the acceleration due to gravity is actually the curvature of space and time — the path itself stoops downward.

The net force on the box is equal to 4N. Therefore, option (1) is correct.

The net force can be described as the vector sum of forces acting on a particle or object. The net force can be defined as a single force showing same the effect of the original forces on the particle's motion. Net force gives the same acceleration as all those actual forces together.

The net force becomes the resultant force. It has the same effect on the rotational motion as all actual forces taken together by the object. Force is a vector quantity as it has a magnitude and a direction.

In the given problem, the applied force is in the opposite direction of the frictional force so we can find the net force by subtracting these two forces.

Given, the applied force to push the box = 5N

The frictional force on the box, = 1 N

The net force on the box = 5N + (-1N) = 4N

The Planck model for the black body and the emission spectrum of the atoms allows to find the results for the peaks in the spectrum of stars is:

The stars are very hot celestial bodies by nuclear fusion processes, in a good approximation they approximate an ideal body that absorbs or emits all the radiation called black body.

A black body is a cavity in thermal equilibrium at a dated temperature with a small hole, this hole is the so-called black body and its emission spectrum was explained by Planck, with the assumption that the energy is

             E = h νν

Where h is Planck's constant and ν is the frequency of the radiation. In the attachment we see the emission spectrum of a black body for various temperatures.

If in the material under study we have in addition the emission characteristics of some elements, it is energy appears as peaks in the emission spectrum and as black bands o valley in an absorption spectrum, therefore the existence of the structure is in a test of the existence of chemical elements within the stars.

In the attachment we can see the spectrum of a dwarf star where we can appreciate the spectrum of the black body and the emission and absorption lines of the chemical elements inside the star.

In conclusion using the Planck model for the black body and the emission spectra of the atoms we can find the results for the peaks in the spectrum of stars is:

If David was driving at a velocity of 5 m/s and accelerates to a velocity of 8 m/s in 4 seconds, David's acceleration is 0.75 [tex]m/s^2[/tex].

Given the following data:

To find David's acceleration:

Acceleration is calculated by subtracting the initial velocity from the final velocity and dividing by the time.

Mathematically, acceleration is given by the formula;

[tex]Acceleration = \frac{V_f\; - \;V_i}{t}[/tex]

Where:

Substituting the given parameters into the formula, we have;

Coastal oceans are commonly defined as the areas from the shoreline to the outer edge of the continental margin. They connect the continents to the open ocean and serve as a link for transporting organic and inorganic, natural and anthropogenic material from land to sea.

Coastal oceans in tropical areas have similar characteristics to their temperate counterparts. ... Coral reefs are biologically diverse and rich habitats that occur in relatively nutrient-poor environments along coastlines.
