Aconducting single-turn circular loop with a total resistance of 4.50 ω is placed in a time-varying magnetic field that produces a magnetic flux through the loop given by φb = a + bt2 − ct3, where a = 7.00 wb, b = 12.5 wb/s−2, and c = 5.50 wb/s−3. φb is in webers, and t is in seconds. what is the maximum current induced in the loop during the time interval t = 0 to t = 1.70 s?

Explanation:

Given

Resistance

Flux

emf induced

Maximum value of will be at

therefore

i at

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
