Kryger [21]

Answer:

the magnitude of the magnetic field is 0.45 mT

Explanation:

Knowing the formula

B = $\frac{m0* (i - i')}{2* Pi* r}$

i = 3A i' = 0A

B = $\frac{4*3.1416e^{-7} * (3-0) }{2*3.1416*0.012}$

B = 0.45 mT

An electric vehicle starts from rest and accelerates at a rate a1 in a straight line until it reaches a speed of v. The vehicle

levacccp [35]

(a) $t=\frac{v}{a_1}+\frac{v}{a_2}$

In the first part of the motion, the car accelerates at rate $a_1$ , so the final velocity after a time t is:

$v = u +a_1t$

Since it starts from rest,

u = 0

So the previous equation is

$v= a_1 t$

So the time taken for this part of the motion is

$t_1=\frac{v}{a_1}$ (1)

In the second part of the motion, the car decelerates at rate $a_2$ , until it reaches a final velocity of v2 = 0. The equation for the velocity is now

$v_2 = v - a_2 t$

where v is the final velocity of the first part of the motion.

Re-arranging the equation,

$t_2=\frac{v}{a_2}$ (2)

So the total time taken for the trip is

$t=\frac{v}{a_1}+\frac{v}{a_2}$

(b) $d=\frac{v^2}{2a_1}+\frac{v^2}{2a_2}$

In the first part of the motion, the distance travelled by the car is

$d_1 = u t_1 + \frac{1}{2}a_1 t_1^2$

Substituting u = 0 and $t_1=\frac{v}{a_1}$ (1), we find

$d_1 = \frac{1}{2}a_1 \frac{v^2}{a_1^2} = \frac{v^2}{2a_1}$

In the second part of the motion, the distance travelled is

$d_2 = v t_2 - \frac{1}{2}a_2 t_2^2$

Substituting $t_2=\frac{v}{a_2}$ (2), we find

$d_1 = \frac{v^2}{a_2} - \frac{1}{2} \frac{v^2}{a_2} = \frac{v^2}{2a_2}$

So the total distance travelled is

$d= d_1 +d_2 = \frac{v^2}{2a_1}+\frac{v^2}{2a_2}$

How does solubility change with temperature changes?

matrenka [14]

Answer:

Solubility increases with temperature.

Explanation:

-Increasing temperatures, increases the kinetic energy that allows solvent molecules to more effectively break apart the solute molecules.

-This solute molecules are held together by intermolecular attractions which weakens in higher temperatures.

-Solubility therefore increases with increasing temperatures.

How does population stimulate social change?

Dmitry_Shevchenko [17]

Answer:

A change in the size of the population may bring about changes in the culture. For example, food brought to this country by immigrant groups have become common in many American kitchens. Population increases and decreases affect the economy. For example, by increasing the demand for goods and services, a growing population may increase employment and stimulate the economy. An increase in the general population also means that there are more people occupying the same amount of space, which creates more crowded conditions. In addition, the larger population brings increased demand for energy, food, housing, schools, stores, and transportation. People also bring about changes simply by moving from one place to another. Migrations of people within a country can cause social changes, such as the loss of regional distinction within the country. Social and cultural changes also result from changes in the average age of a population. When fewer people are having babies, for example, there is less need for schools, recreation centers, and other services geared toward children.
