Answer:
1449 K
Explanation:
The surface temperature of a star is related to its peak wavelength by Wien's displacement law:

where
T is the surface temperature
b is Wien's displacement constant

So the surface temperature of the star is

Explanation:
To find the resultant force subtract the magnitude of the smaller force from the magnitude of the larger force. The direction of the resultant force is in the same direction as the larger force
Answer:
5.77×10¹⁰ m
Explanation:
From the question,
Applying
Kepler's third law
P² = d³...................... Equation 1
Where P = Planet's period, d = distance between the center of the planet and the sun.
make d the subject of the formula n equation 1
d =
.................. Equation 2
Given: P = 0.24 sidereal.
Substitute the value of P into equation 2
d =
d = 0.386 Au
d = 0.386×1.496×10¹¹
d = 5.77×10¹⁰ m
