The magnitude of the electric field inside the conductor will be 0.208 N/C.

An electric field is an electric property that is connected with any location in space where a charge exists in any form. The electric force per unit charge is another term for an electric field.

Given data;

length of rod = 25 cm = 0.25 m

Potential Difference = 52 mV = 0.052 Volts

The electric field is found as the ratio of the potential difference and the length;

[tex]\rm E =\frac{0.052}{0.25} \\\\ E=0.208 \ N/C[/tex]

Hence,the magnitude of the electric field inside the conductor will be 0.208 N/C.

Plasma osmolarity increases when you give a severely dehydrated person large amounts of pure water.

The electrolyte–water balance of the body is measured by plasma osmolality. This amount can be determined in a variety of ways, including measurement and computation.

Osmolality and osmolarity are two separate measurements that are used interchangeably in everyday situations.

When you are dehydrated, osmolality rises, and when you have too much fluid in your blood, it drops.

The way your body regulates osmolality is unique. When your body's osmolality rises, your body produces antidiuretic hormone.

Hence,plasma osmolarity increases when you give a severely dehydrated person large amounts of pure water.

Explanation:

B = [tex]\frac{U.i}{2pi*r}[/tex]

So, here the r is 0.225 m

The Magnetic field is 4.29 x [tex]10^{-7}[/tex] t

U. = 4π x [tex]10^{-7}[/tex] x i

4.29 x [tex]10^{-7}[/tex] = (4π x [tex]10^{-7}[/tex] x i) / (2π * 0.225)

Cutting  [tex]10^{-7}[/tex]

4.29 = [tex]\frac{4π * i}{2π * 0.225}[/tex]

4π and 2π canceled, left with 2

4.29 = [tex]\frac{2i}{0.225}[/tex]

4.29*0.225 = 2i

0.96525 = 2i

i = [tex]\frac{0.96525}{2}[/tex]

i = 0.482625 A

Explanation:

A scalar quantity is those quantities that only have magnitude and no direction. Therefore the value doesn't change with direction.

(a) The mass of the car is 1,795.92 kg

(b) The initial momentum of the car is 44,897.96 kgm/s.

(c) the change in momentum for the car is 44,897.96 kgm/s..

(d) The time it takes the braking force to bring the car to rest is 69.4 s.

The mass of the car is calculated as follows;

W = mg

m = W/g

m = (17,600)/9.8

m = 1,795.92 kg

Pi = mvi

Pi = 1,795.92 x 25

Pi = 44,897.96 kgm/s

ΔP = Pf - Pi

ΔP = 0(1,795.92) - 44,897.96 kgm/s

ΔP =  - 44,897.96 kgm/s

F = ma

-650 = 1,795.92(a)

a = -650/1,795.92

a = -0.36 m/s²

Answer:

The object obeys the equation

F = M a     on both the earth and the moon (mass does not depend on location)

The problem is a little misleading because if an object has a mass of

10 kg then its weight is 10 kg * 9.8 m/s^2 = 98 Newtons

That means that weight is not expressed in Kg but rather in Newtons

Newton's Law is true on the moon as it is on the earth and F = M a

An object that weighed 10 N on earth would weigh 10 / 6 = 1.67 N on the moon

One must take care in describing a force in units of Newtons not in Kg

The final velocity of the girl after the collision is determined as -4.8 m/s.

The final velocity of the girl is determined from the principle of conservation of linear momentum.

Answer:

Earth rotates eastward, in prograde motion. As viewed from the north pole star Polaris, Earth turns counterclockwise.

The time it takes Earth to rotate so the sun appears in the same position in the sky, known as a solar day, is 24 hours. However, the time it takes Earth to complete one full rotation on its axis with respect to distant stars is actually 23 hours 56 minutes 4.091 seconds, known as a sidereal day.

Earth's axis is an imaginary pole going right through the center of Earth from "top" to "bottom." Earth spins around this pole, making one complete turn each day. That is why we have day and night, and why every part of Earth's surface gets some of each. Earth has seasons because its axis doesn't stand up straight.

Earth and sun are part of the solar system, with the sun at its centre. An Earth day is 24 hours because the Earth spins on its axis once every 24 hours. At any one time half of the Earth's sphere is in sunlight (day) while the other half is in darkness (night).

The Earth's axis runs from the North Pole to the South Pole. It takes the Earth 24 hours, or one day, to make one complete rotation around this invisible line. As the Earth rotates, each area of its surface gets a turn to face and be warmed by the sun. This is important to all life on Earth

Answer:

Approximately [tex]21.6\; {\rm m\cdot s^{-1}}[/tex], assuming that the coefficient of kinetic friction between the tires and the ground stays the same.

Explanation:

Let [tex]\mu_{k}[/tex] denote the coefficient of kinetic friction between the tires and the ground.

Let [tex]m[/tex] denote the mass of the truck. Let [tex]g[/tex] denote the gravitational field strength. The weight of this truck would be [tex]m\, g[/tex]. Since the curve is flat, the magnitude of the normal force [tex]F_\text{normal}[/tex] between the truck and the ground would also be [tex]m\, g\![/tex].

Let [tex]v = 32.5\; {\rm m\cdot s^{-1}}[/tex] denote the speed at which the truck goes around the curve with a radius of [tex]150\; {\rm m}[/tex]. The (horizontal) centripetal acceleration of the truck would be:

[tex]\displaystyle a = \frac{v^{2}}{r}[/tex].

The horizontal net force on the truck (of mass [tex]m[/tex]) would need to be exactly:

[tex]\displaystyle F_\text{net} = m\, a = \frac{m\, v^{2}}{r}[/tex].

The friction between the tires of the truck and the ground is the only horizontal force on the truck. Thus, this friction would need to supply the entirety of this horizontal net force:

[tex]\displaystyle F_\text{friction} = F_\text{net} = \frac{m\, v^{2}}{r}[/tex].

Notice that increasing [tex]v[/tex] would require an increase in the kinetic friction between the truck, [tex]F_\text{friction}[/tex]. However, since [tex]F_\text{friction}\![/tex] is at most [tex]\mu_{k}\, F_\text{normal}[/tex] (which is equal to [tex]\mu_{k}\, m\, g[/tex]):

[tex]\begin{aligned}\frac{m\, v^{2}}{r} &= F_\text{friction} \\ & \le \mu_{k}\, F_\text{normal} \\ &= \mu_{k}\, m\, g\end{aligned}[/tex].

Therefore, when the radius of the curve is [tex]r^{\prime}[/tex], the maximum velocity of this truck would be:

[tex]\begin{aligned}v^{\prime} &= \sqrt{\mu_{k}\, g\, r^{\prime}}\end{aligned}[/tex].

Likewise, it is possible to express [tex]\mu_{k}[/tex] in terms of [tex]r[/tex], [tex]g[/tex], and max speed [tex]v[/tex]:

[tex]\displaystyle \mu_{k} = \frac{v^{2}}{r\, g}[/tex].

Substitute this expression for [tex]\mu_{k}[/tex] back into the expression for [tex]v^{\prime}[/tex]:

[tex]\begin{aligned}v^{\prime} &= \sqrt{\mu_{k}\, g\, r^{\prime}} \\ &= \sqrt{\frac{v^{2}}{r\, g}\, g\, r^{\prime}} \\ &= \sqrt{v^{2}\, \frac{r^{\prime}}{r}}\end{aligned}[/tex].

Given that [tex]v = 32.5\; {\rm m\cdot s^{-1}}[/tex], [tex]r = 150\; {\rm m}[/tex], and [tex]r^{\prime} = 66.0\; {\rm m}[/tex]:

[tex]\begin{aligned}v^{\prime} &= \sqrt{v^{2}\, \frac{r^{\prime}}{r}} \\ &= \sqrt{(32.5\; {\rm m\cdot s^{-1}})^{2} \times \frac{66.0\; {\rm m}}{150\; {\rm m}}} \\ &\approx 21.6\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].
