Asquare, single-turn coil 0.132 m on a side is placed with its plane perpendicular to a constant magnetic field. an emf of 27.1 mv is induced in the winding while the area of the coil decreases at a rate of 0.0785 m2 /s. what is the magnitude of the magnetic field? answer in units of t.

What are segments of dna that code for a particular trait. a combination of dna and proteins make up what

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
