Answer:
the formula for the force of gravity depends inversely of the distance and directly of the masses.
This means that if the masses increase and their distance remains the same the force will increase proportionally.
Answer:
None of the stars give of light that is red-shifted
Explanation:
Motion of the observer or the source will cause a change in the wavelength of a wave. This is known as the Doppler effect. When an object and observer are getting close, blue shift occurs i.e., the wavelength gets shorter. When an object and observer are getting farther red shift occurs i.e., the wavelength gets longer.
Here, both the stars are getting closer to us so blue shift will occur.
Answer:
acceleration = 0.2625 m/s²
Explanation:
acceleration = ( final velocity - initial velocity ) / time
Here the final velocity is 10.6 m/s and initial velocity is 6.4 m/s and time is 16 s.
using the equation:
acceleration = ( 10.6 - 6.4 ) / 16
= 0.2625 m/s²
Your answer is c. electrons that are available for bonding.
