A fishbowl has a circular opening with a diameter of 15 cm. The fishbowl sits upright on a table in a magnetic field of 0.00110 T that is directed horizontally. What is the flux through the glass of the bowl?

−7.77 × 10−5 Wb
−1.9 × 10−5 Wb
−1.7 × 10−4 Wb
0.0 Wb

−1.9 × 10−5 Wb

Explanation:

Magnetic flux is the product of average magnetic field times the perpendicular area that is crosses times the angle between planar area and magnetic flux

Finding the area

Area = πr² = 3.14*0.075*0.075

Area=0.01767 m²

Magnetic flux = 0.01767*0.00110*cos 0

Magnetic flux =0.000019 = −1.9 × 10−5 Wb

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5
