A 150Ω resistor is connected to a coil with 30 turns and a cross sectional area of 0.02m2. A magnet is lowered as shown in the figure. The magnetic field increases from 0.01T to 0.06T in 20ms. Find the magnitude of the current going through the resistor. I = 0.1 A
I = 0.2 A
I = 0.01 A
I = 0.02 A
I = 0.001 A

pls pls answer fast

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.

leave feedback if u need : )

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
