Zero.
Acceleration is defined as the change in velocity over time.
Since in your case there is no change, there is no acceleration, so it is zero:
Or in formula: <span>a=<span><span>Δv</span>t</span></span>
Where a=acceleration, <span>Δv</span>=change in velocity and t=time
The mass of ball a is twice the mass of ball b:

This means that the initial potential energy of ball a (

) is twice the potential energy of ball b (

):

When the two balls reach the ground, the potential energy of each ball has converted into kinetic energy (since now their altitude is h=0), because the total mechanical energy of each ball must be conserved. Therefore:


and so the kinetic energy of ball a must be twice the kinetic energy of ball b:
1) % = (Wo /Wi) * 100
Solve for Wo => Wo = (% / 100) * Wi
For example, % =30% and Wi = 250 => Wo = (30 /100) * 250 = 0.30 * 250 = 75
Wo = 75
2) % = (Wo / Wi) * 100
Solve for Wi
=> Wi = Wo * (%/100)
For example, Wo = 125 and % = 40%
=> Wi = 125 * (40 / 100) = 125 * 0.40 = 50
Wi = 50
Answer:

Explanation:
Given that
B(y, t) = k y ³t²
To find the total flux over the loop we have to integrate over the loop

Given that loop is square,so

B(y, t) = k y ³t²


We know that emf given as


So
