Answer:
The induced voltage in the coil is 0.25 V.
Explanation:
It is given that,
Area of a square coil is 2 cm or 0.02 m
Number of turns in the wire is 2500
A uniform magnetic field perpendicular to its plane is turned on and increases to 0.25 T during an interval of 1.0 s.
We need to find the induced voltage in the coil. According to Faraday's law, the induced emf in the coil is given by the rate of change on magnetic flux. So,
So, the induced voltage in the coil is 0.25 V.
Answer:
All the statements are true
Explanation:
A) Wires are in tension.
It is true because the loads exerted on the bridge are taken by each of the cables of the bridge. these cables transmit the force to the pillars or columns of the bridge. (check the image 01)
B) Large posts are in compression.
It is true each of the loads of the cables is tension, are transmitted to the columns of the bridge, in this way the balance will be maintained (check the image 01)
C) The bridge deck is both in tension and compression.
Yes it is true, the superior part of the deck will be in compression and the inferior part will be in tension, this can be seen in the image 02
