Explanation:
Unbalanced Forces in Action
Unbalanced forces can change the motion of an object in two ways. ... Second, when unbalanced forces act on a moving object, the velocity of the object will change. Remember that a change in velocity means a change in speed, direction or both speed and direction.
<span>From Ohm's law. V = IR. Where R = 2 Ohms. To calculate the induced current I; We need to calculate the electromotive force or voltage, V. From Faraday's law induced EMF = (The rate of change of magnetic flux density x Area)/ (changein time). Or EMF = BA/t. Where B = Bf - Bi. And BA = Bf* A - Bi* A.
Bf = 2.00 and Bi = 0.500 and t = 0.93s and the area, A = 7.1 cm^2 is 0.000071 m^2. 2
So Emf = 2.00 (0.000071) - 0.500(0.000071) /(0.93) = 1.0654 * 10^(-4)/ 0.93 = 1.1415 * 10^(-4).
Substituting into ohms law, we have,
I = (1.1415 * 10^(-4)) / 2 = 0.57075 * 10^(-4)</span>
The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now (and it could still be stretching).
It depends how you want it to work do you want to take a picture oh yea and to do that you must create a account btw
Answer:
The speed of player is given by
Explanation:
The time of flight for a projectile motion is given by
(i)
where t is the time of flight, v is the initial speed, and α is the angle.
Now the person must also reach the impact point of ball in the same time as above.
Now the total distance D the player needs to cover is basically R horizontal range of projectile minus the distance d, range R is given by,
Now the distance the player must cover is given by
D= R-d
D= 
- d
(ii)
Now the average speed of player is given by
(iii)
Replacing the values of D and T from eq. (i) and (ii) in eq. (iii).
