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.

They hit the ground at the same time
V = m1 u1 - m2 u2 / m1
v = 0.01 * 500 - 2 * 1.4 / 0.01
v = 220 m/s

Answer:
The charge on the bead is 
Explanation:
From the question we are told that
The mass of the bead is 
The magnitude of the electric field is 
The acceleration of the bead is 
Generally, the electric force on the bead is mathematically represented as

Where q is the charge on the bead
Now the gravitational force opposing the upward movement of the bead is mathematically represented as

Generally the net force on the bead is mathematically represented as

=> 
Now substituting values
