For a transformer, the ratio between the number of turns of primary and secondary coil is the same as the ratio between the voltages on the two coils:
Where
and
are the number of turns in the primary and secondary coils, while
and
are the voltages on the two coils.
Using the data of the problem:
,
and
, we can find
, the number of turns of the secondary coil:
The speed of the water in the wider part will be 1.194 m/sec. Speed is a time-based quantity. Its SI unit is m/sec.
<h3> What is speed?</h3>
Speed is defined as the rate of change of the distance or the height attained.
The given data in the problem is;
The initial diameter is,
initial radius,
The initial crossection area;
The final crossection area;
The initial flow rate is;
R = density ×velocity ×area
The speed of the water in the wider part will be;
From the continuity equation;
Hence, the speed of the water in the wider part will be 1.194 m/sec.

A combination of longitudinal and transverse. :) yw
Answer: option A) initially increases, then decreases.
Justification:
The increase of the rate of effective collisions among particles as the temperature increases is explained by the collision theory in virtue of the increase of the kinetic energy.
This is, as the temperature increase so the kinetic energy increase and the higher the kinetic energy the greater the number of collisions and the greater the chances that this energy overcome the activation energy (the energy needed to start the reaction).
Now, as the reaction progress the number of reactants particles naturally decrease (some of them have been converted into product) so this lower number of particles means lower concentration which means lower collisions and, thereafter, a decrease in the reaction rate.
