The magnetic field is uniform and out of the page inside a circle of radius r, and is essentially zero outside the circular region (see the figure). the magnitude of the magnetic field is changing with time; as a function of time the magnitude of the magnetic field is (b0 + bt3). r1 = 2.4 cm, r2 = 45 cm, b0 = 1.5 t, b = 1.1 t/s3, t = 0.9 s, and r = 16 cm. uploaded image

(b) what is the magnitude of the electric field at location p? (hint: remember that "emf" is the integral of the non-coulomb electric field around a closed path.)
n/c
(d) what is magnitude of the "curly" electric field at location q?
n/c

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

in physics zero. in muscle fatigue could be high

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
