0.078 times the orbital radius r of the earth around our sun is the exoplanet's orbital radius around its sun.
Answer: Option B
<u>Explanation:</u>
Given that planet is revolving around the earth so from the statement of centrifugal force, we know that any
The orbit’s period is given by,
Where,
= Earth’s period
= planet’s period
= sun’s mass
= earth’s radius
Now,
As, planet mass is equal to 0.7 times the sun mass, so
Taking the ratios of both equation, we get,
Given 
and 
higher temp = higher energy = higher frequency = shorter wavelength
<h3><u>Answer;</u></h3>
4. the material the object is made of and the color of light that strikes it
<h3><u>Explanation;</u></h3>
- The color of an object is the wavelength of light that the object reflects, which is determined by the arrangement of electrons in the atoms of the material making the object.
- <em><u>We could therefore say that the color of object depends on or is determined by the material making up the object as this determines the the wavelengths of light the object reflects. Lastly, the color of light source also determines the color of the object.</u></em>
To know where they’re heading to
Answer:
have a component along the direction of motion that remains perpendicular to the direction of motion
Explanation:
In this exercise you are asked to enter which sentence is correct, let's start by writing Newton's second law.
circular movement
F = m a
a = v² / r
F = m v²/R
where the force is perpendicular to the velocity, all the force is used to change the direction of the velocity
in linear motion
F = m a
where the force is parallel to the acceleration of the body, the total force is used to change the modulus of the velocity
the correct answer is: have a component along the direction of motion that remains perpendicular to the direction of motion
