Answer:
The definition of a fulcrum is a pivot point around which a lever turns, or something that plays a central role in or is in the center of a situation or activity.
(u) = 20 m/s
(v) = 0 m/s
<span> (t) = 4 s
</span>
<span>0 = 20 + a(4)
</span><span>4 x a = -20
</span>
so, the answer is <span>-5 m/s^2. or -5 meter per second</span>
Against due to the fact that they grow up and gravity goes down.
The input voltage is 120 V and the transformer is a step up transformer due to increase in the voltage induced in the secondary coil.
<h3>
Input voltage </h3>
The input voltage of the transformer is the voltage of the primary coil and it is calculated as follows;
Ns/Np = Es/Ep
where;
- Ns is the number of turn in the secondary coil
- Np is the number of turn in the primary coil
- Es is the secondary voltage
- Ep is the primary voltage
2X/X = 240/Ep
2 = 240/Ep
Ep = 240/2
Ep = 120 V
Thus, the transformer is a step up transformer due to increase in the voltage induced in the secondary coil.
