i think its B)... im not sure so dont take it seriously
Answer:
Secondary voltage on second transformer is 200 volt.
Explanation:
It is given two transformer
Let us consider first transformer.
Number of turns in primary
Numb er of turns in secondary
Now consider second transformer
Number of turns in primary
Number of turns in secondary
Now it is given that same voltage of 50 volt is applied to primary of both the transformer.
For second transformer
So secondary voltage on second transformer is 200 volt
Answer:
2.6 m
Explanation:
The work done by the bird is given by
where
F is the force exerted
d is the distance covered
In this problem, we know:
is the work
is the force
Solving the equation for d, we find the distance covered by the bird:
Explanation:
(a) The period of a wave is the time required for one complete cycle. In this case, we have the time of five cycles. So:
(b) The frequency of a wave is inversely proportional to its period:
(c) The wavelength is the distance between two successive crests, so:
(d) The speed of a wave is defined as:
Answer:
150 newtons
Explanation:
F = ma
force = mass * acceleration
the mass is 10 kg, and the accelration is 15 m/s^2
10*15 = 150
the force unit that matches with meters/second and kg is newtons
F =ma
150 newtons = 10 kg * 15 m/s^2
