She can use the information of redshift of a celestial body is to find the age and distance of the object.
<h3>What is red shift?</h3>
'Red shift' is a critical idea for astronomers. The frequency of the light is increased, so the light is observed as moving towards the red side of the range.
Tabitha knows the redshift value of a particular celestial object. She uses this information to observe the consequence of the redshift.
Thus, the red shift value is used to determine the age and distance of the object.

You would have to subtract the mass number with atomic number which will give you 119 number of neutrons.
Answer: speed = 446.4m/s
Explanation: 1000mph implies that 1000 miles / 1 hour.
But it has been given that 1mile = 1609m,
hence
1000 miles = 1000 * 1609 = 1,609,000m
And I hour = 3600s
Hence 1000mph = 1,609,000/ 3600
1000 = 446.4m/s
