Answer:

Explanation:
From the question we are told that
Speed of star 
Distance of spectral line 
Generally the equation for wavelength with respect to spectral lines is mathematically given by

where



therefore


Generally the equation for new wavelength is mathematically given as



Therefore

Answer:
Conduction is usually faster in certain solids and liquids than in gases. Materials that are good conductors of thermal energy are called thermal conductors. Metals are especially good thermal conductors because they have freely moving electrons that can transfer thermal energy quickly and easily.
Heat transfer by convection happens through the air, and there are millions of minuscule air spaces between the fibers. Heat transfer by radiation is also slow since one fiber must radiate its heat to another.
When we give heat then kinetic energy is increase and this heat is transferred from hot metal to cold metal through this free electrons. As in insulator the free electrons are negligible so that the heat is not transferred from hot junction to cold junction due to absence of this free electrons.

Hello. You did not present the combinations the question refers to, which makes it impossible for this question to be answered accurately. However, I will try to help you in the best possible way.
To present the total force you must use the following formula: Mass x Acceleration.
To calculate the total mass, you must use the formula: Force / acceleration.
To calculate the acceleration you must use the formula: Force / mass.
