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.

Answer:

It is called gravitational force.

Would you expect the spectrum of a blackbody radiator to have peaks and valleys like the spectrum of WF4-358? Why or why not? Define blackbody radiators in your answer.

Answers

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 general shape is that of a black body and the peaks are due to chemical compounds or elements in the star.

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:

The general shape is that of a black body and the peaks are due to chemical compounds or elements in the star.

A plane moves 599 m northeast along a runway.
If the northern component of this displacement
is 89 m, how large is the eastern component?

Answers

The eastern component of the plane's displacement is 592.35 m.

The given parameters;

the resultant of the plane displacement = 599 mthe northern component of this displacement, Y = 89 mLet the eastern component of this displacement = X

The eastern component of the plane's displacement is calculated by applying Pythagoras theorem as follows;

X²  + Y² = 599²

X² + 89² = 599²

X² = 599²  - 89²

X² = 350880

X = √350880

X = 592.35 m

Thus, the eastern component of the plane's displacement is 592.35 m

The period of rotation of Mars is 1 day and 37 minutes. Determine its frequency of rotation in Hertz.

Answers

The frequency of rotation of Mars is 0.0000113 Hertz.

Given the following data:

Period = 1 day and 37 minutes.

To find the frequency of rotation in Hertz:

First of all, we would convert the the value of period in days and minutes to seconds because the period of oscillation of a physical object is measured in seconds.

Conversion:

1 day = 24 hours

24 hours to minutes = [tex]60[/tex] × [tex]24[/tex] = [tex]1440[/tex] minutes

[tex]1440 + 37 = 1477 \; minutes[/tex]

1 minute = 60 seconds

1477 minute = X seconds

Cross-multiplying, we have:

[tex]X = 60[/tex] × [tex]1477[/tex]

X = 88620 seconds

Now, we can find the frequency of rotation of Mars by using the formula:

[tex]Frequency = \frac{1}{Period}\\\\Frequency = \frac{1}{88620}[/tex]

Frequency of rotation = 0.0000113 Hertz

Therefore, the frequency of rotation of Mars is 0.0000113 Hertz.

David was driving at a velocity of 5 m/s. He accelerates to a velocity of 8 m/s in 4 seconds. What is the acceleration?

Identify the given variables and the unknown
x distance


t time


Vi initial velocity


Vf final velocity


a acceleration


F force

Answers

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:

Initial velocity, Vi = 5 m/sFinal velocity, Vf = 8 m/sTime, t = 4 seconds.

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:

Vf is the final velocity.Vi is the initial velocity.t is the time measured in seconds.

Substituting the given parameters into the formula, we have;

[tex]Acceleration = \frac{8\; - \;5}{4}\\\\Acceleration = \frac{3}{4}[/tex]

Acceleration = 0.75 [tex]m/s^2[/tex].

Therefore, the David's acceleration is 0.75 [tex]m/s^2[/tex].

What are the similarities between coral reefs and costal ecosystems

Answers

Answer:

A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. ... Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral.

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. Areas that have too many nutrients often harbor too much algal growth to sustain coral growth.,

∆T = 40-20 = 20°C

Find the Energy!

solution :

E =m. sh. ∆T

= 20 × 0.39 × 20

= 156 J

♪Answer : mass = 20g sh = 0.39j/g°c∆T = 40° - 20° = 20°

So, energy required is

Energy = mass*sh*∆T

About a thousand billion times! Because neutron stars are so dense, they have intense gravitational and magnetic fields.
