Acoil 3.95 cm radius, containing 520 turns, is placed in a uniform magnetic field that varies with time according to b=( 1.20Γ—10βˆ’2 t/s )t+( 3.45Γ—10βˆ’5 t/s4 )t4. the coil is connected to a 560-Ο‰ resistor, and its plane is perpendicular to the magnetic field. you can ignore the resistance of the coil.
a-)find the magnitude of the induced emf in the coil as a function of time.

find the magnitude of the induced emf in the coil as a function of time.

e= 1.07Γ—10βˆ’2 v +( 1.05Γ—10βˆ’4 v/s3 )t3
e= 3.36Γ—10βˆ’2 v +( 8.26Γ—10βˆ’5 v/s3 )t3
e= 3.36Γ—10βˆ’2 v +( 3.30Γ—10βˆ’4 v/s3 )t3
e= 1.07Γ—10βˆ’2 v +( 3.30Γ—10βˆ’4 v/s3 )t3
b-)what is the current in the resistor at time t0 = 5.25 s ?

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmnβˆ’azm)c2?
