A boat is moving due east in a region where the earth's magnetic field is 5.0×10⁻⁵ NA⁻¹ m⁻¹ due north and horizontal. The boat carries a vertical aerial 2 m long. If the speed of the boat is 1.50 ms⁻¹ , the magnitude of the induced emf in the wire of aerial is:

Induced emf is given by:

ε= Bvl

On putting the values we get

=5×10

−5

×1.50×2

=0.15mV

Hope these helped have a wonderful Christmas break ❄️

Roads, canals, and railroads all greatly impacted Americans' lives during the nineteenth century. Roads allowed for an easier commute for Americans, along with access to more places. Railroads were similar, but they provided an even quicker way to get to places, and places that were even farther away. Railroads broadened the amount of places an average human could reach across the country. Not only did roads and railroads benefit those using them, but they also provided jobs for those building them. Lastly, canals were important waterways to Americans. Boats and ships could transport many needs and goods through canals. One remarkable thing that was brought to people around the country through canals was water for irrigation. With the use of waterways for transportation and trade, people could receive their needs and goods more efficiently, which would befit them and their families.
