Answer:

When drawing free-body diagrams, each force is represented by an arrow (a vector). The size of the arrow shows the relative magnitude of the force, while the direction the arrow is pointing tells us in which direction the force is acting

One long wire carries current 30.0 A to the left along the x axis. A second long wire carries current 50.0 A to the right along

strojnjashka [21]

Answer:

y = -0.42 m

1.16*10^-4 T(-k)

-1.73*10^4 N/C (j)

Explanation:

(a) Above the pair of wires, The field out of the page of the 50 A current will be stronger than the (—k) field of the 30 A current (k).

Between the wires, both produce fields into the page.

below the wires, y = - | y |

B = u_o*I/2πr (-k) + u_o*I/2πr (k)

0 = u_o/2πr[50/ | y |+0.28 (-k) + 30/| y | (k) ]

50 | y | = 30(| y | + 0.28)

| y | = -y

-50 y = 30*(0.28 - y)

y = -0.42 m

b) B = u_o*I/2πr (-k) + u_o*I/2πr (k)

B = 4π*10^-7/2π[ 50/0.28 -1 (-k) +30/1(-k) ]

= 1.16*10^-4 T(-k)

F = qv*B

F = (-2*10^-6)*(150*10^6(i) )(1.16*10^-4(-k))

F = 3.47*10^-2 N(-j)

c) F_e = qE

E = F_e/q

E = 3.47*10^-2/-2*10-6

= -1.73*10^4 N/C (j)

Let's practice calculating the frictional force of a skier on old "woody" skis and wet snow. The skier has a mass of 58 kg. The

kicyunya [14]

Answer:

Kinetic frictional force will be equal to 56.84 N

Explanation:

We have given mass of the skier m = 58 kg

Acceleration due to gravity $g=9.8m/sec^2$

Coefficient of kinetic friction $\mu _k=0.1$

We have to find the kinetic frictional force

Kinetic frictional force is given by

$F_K=\mu _Kmg=0.1\times 58\times 9.8=56.84N$

So kinetic frictional force will be equal to 56.84 N

Which of the following types of energy is potential energy A. gravitational energy

katovenus [111]

There are many forms of energy, but they can all be put into two categories: kinetic and potential. Kinetic energy is motion––of waves, electrons, atoms, molecules, substances, and objects. Potential energy is stored energy and the energy of position––gravitational energy
