What is the magnetic field at a point p midway between two wires, each carrying a current of 29 amps in opposite directions and separated by a distance of 13.7 cm? select one: a. 4.2e-5 tesla b.0.00 tesla, the fields cancel c. 8.5e-5 tesla d. 5.3e-4 tesla e. 1.7e-4 tesla

e)

Explanation:

Given that

I= 29 A

Distance ,r=13.7 cm

As we know that when current is flowing in the same direction then magnetic field will be in the opposite direction and when current is flowing in the opposite then produce magnetic field will be in same direction.

Here current is flowing in opposite direction that is why we add magnetic field.

Magnetic field ,B

Now by putting the values

r = 13.7/2 = 6.85 cm

r=0.0685 m

B=0.000169 T

So the option e is correct.

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.

explanation:

  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
