Answer:
Explanation:
Given that,
An object starts from rest at the origin (x₀ = 0) and travels in a straight line with a constant acceleration (a = constant).
The relation between the position (x) and time (t) is given by :
Let v is the velocity of the object.
Let a is the acceleration of the object. It is given by :
So, the acceleration of the object is . Hence, this is the required solution.

I think She or he said
“Transports energy from one point to another”
I would answer but I don’t understand
{Español}
Creo que ella o él dijo
“Transporta energía de un punto a otro”
Respondería, pero no entiendo
Answer:True
Explanation:
By applying Gauss law Electric field is zero everywhere inside the conductor.
According to Gauss law the net flux of an electric field in a closed surface is directly proportional to the enclosed electric charge.
For example
For a Gaussian surface inside a conductor all the points have zero electric field as the system is in equilibrium. This implies net flux is zero and net charge inside is zero . So all the charge must be at surface on conductor.
Answer:
(A-) Number of turns in secondary coil will be<u> less than 125.</u>
(B-) EXPLAIN- The voltage is to be lowered.<u> The voltage will be reduced from 120 to 9 volts.</u> As a result, a<u> step down transformer </u>will be used, indicating that the secondary coil's number of turns would be less than 125.
(C-)<u> The number of turns on the secondary coil is 12.5</u>
<u></u>
Explanation:
- STEP DOWN TRANSFORMER - A step-down transformer transforms high voltage (HV) and low current from the transformer's primary side to low voltage (LV) and high current on the secondary side. A phase down transformer is the opposite of this.
In electrical networks and transmission lines, a step-down transformer can be used in a number of ways.
<u>Step down transformer formula-</u>
We are given with the -
Primary voltage = 120V
Secondary voltage
Number of primary turns
- <u>To calculate the number of turns on the secondary coil -</u>
Since , the transformer ratio is given as -
So, the number of turns on the secondary coil is -
Putting , the given values -:
= 12.5
<u>Therefore , the number of turns on secondary coil is 12.5 .</u>
