Answer: the answer is 35.4

Explanation: the formula is mass x acceleration = tension - weight

weight is (3kg x 9.8 m/s)

acceleration is 2 m/s

mass = 3kg

What is the relation between electric intensity dn flux
Zepler [3.9K]

The relation between the electric intensity and electric flux is that the electric flux is equal to the scalar product of electric flux intensity and vector area.

<h3>What is the relation between electric intensity and flux?</h3>

The electric field is the field, which is surrounded by the electric charged. The electric field is the electric force per unit charge.

  • The intensity of this electric field is the number of electric field lines which are pass perpendicular to the unit element of fixed area.
  • The flux of this electric field is the number of electric field lines which are pass normally to the fixed area.

The electric flux can be given as,

d\phi =\vec E \;dA\cos \theta

When angle is zero,

d\phi =\vec E \;dA\times1\\d\phi =\vec E \;dA

Thus, the total flux is,

\phi=\oint_{}^{}\vec E.d\vec A

Thus, the relation between the electric intensity and electric flux is that the electric flux is equal to the scalar product of electric flux intensity and vector area.

Doug, who runs track for his high school, was challenged to a race by his younger brother, matt. Matt started running first, and
eduard

The speed of Matt is 10 mph.

Doug runs 2 miles an hour faster than Matt, so let Matt’s speed equal x miles per hour. Then Doug’s speed equals x + 2 miles per hour. Each lap is one-quarter of a mile, so Doug runs 1.5 miles in the time it takes Matt to run 1.25 miles.

Rate of Matt is x

Rate of Dough is (x + 2)

Time taken by Matt is 1.25/x

Time taken by Dough is 1.25/(x + 2)

Distance covered by Matt is 1.25

Distance covered by Dough is 1.5

Dough and  Matt  took the same amount of time from the time Doug started, so make an equation by setting the two times in the chart equal to each other, and then solve for x:

            \frac{1.5}{(x + 2)} = \frac{1.25}{x}

              1.5x = 1.25(x + 2)

              1.5x = 1.25x + 2.5

           0.25x = 2.5

                   x = 10

So Matt ran at 10 miles per hour.
