Given:
Acceleration is uniform and acceleration (a) = 10 m/s^2
Now it has been mentioned for the first 2 secs the acceleration is 10m/s^2 .
Hence velocity= acceleration x time
Velocity= 10 x 2 = 20 m/s
Consider s as the distance traveled in the 3rd second.
Now we know s= ut+1/2(at^2)
Where s is the distance measured in m.
u is the initial velocity measured in m/sec
t is the time taken for the object to travel the above distance. This is equal to one second as we need to calculate the distance traveled between 3rd and 2nd second.
t = (3-2)= 1 sec
Substituting the given values in the above formula we get
s = 20 x1 + 1/2 (10 x 1 x 1)
s = 25 m
Thus the distance traveled by the object in the 3rd second is 25 m
The work done by the electric field is equal to the loss of electric potential energy of the proton in moving from its initial location to its final location:
where
is the proton charge,
and
are the voltages in the final and initial locations. Substituting, we get
Yes, this is accurate. While "dark matter" might exist, it is still more of a theory, it is not yet defined properly. As far as we truthfully know, the entire universe is just matter and energy.
As they evolved and adapted, those of the fittest survived to reproduce. Those that did not adapt, died.
Answer:
<em>The primary coil has 13,400 turns</em>
Explanation:
<u>Voltage Transformers</u>
A transformer is an electrical apparatus that converts an alternating electrical voltage to another. Step-down transformers lower the voltage from higher levels (kilovolts) to consumer levels (120/240 Volts).
The ratio between both voltages can be computed as
Where V1 is the primary voltage and V2 is the secondary voltage. This ratio depends on the turns ratio of the coils wounded in a common magnetic core.
Being N1 the number of turns of the coils of the primary side and N2 the number of turns in the secondary coil. Both relations give us
Solving for N1
We have:
Calculate N1
The primary coil has 13,400 turns
