                    (500 mL) · (1 liter / 1,000 mL)

                 =    (500 / 1,000)  liter

                 =      1/2 liter

A charged paint is spread in a very thin uniform layer over the surface of a plastic sphere of diameter 18.0 cm , giving it a ch
vladimir1956 [14]

A) The electric field inside the paint layer is zero

B) The electric field just outside the paint layer is 3.2\cdot 10^7 N/C (radially inward)

C) The electric field at 6.00 cm from the surface is 1.2\cdot 10^7 N/C (radially inward)

Explanation:

A)

We can solve the problem by applying Gauss Law, which states  that the electric flux through a Gaussian surface must be equal to the charge contained in the surface divided by the vacuum permittivity:

\int EdS = \frac{q}{\epsilon_0}

where

E is the magnitude of the electric field

dS is the element of the surface

q is the charge contained within the surface

\epsilon_0 is the vacuum permittivity

By taking a sphere centered in the origin,

\int E dS = E \cdot 4\pi r^2

where 4\pi r^2 is the surface of the Gaussian sphere of radius r.

In this problem, we want to find the electric field just inside the paint layer, so we take a value of r smaller than

R=9.0 cm = 0.09 m (radius of the plastic sphere is half of the diameter)

Since the charge is all distributed over the plastic sphere, the charge contained within the Gaussian sphere is zero:

q=0

And therefore,

E4\pi r^2 = 0\\\rightarrow E = 0

So, the electric field inside the plastic sphere is zero.

B)

Here we apply again Gauss Law:

E\cdot 4 \pi r^2 = \frac{q}{\epsilon_0}

In this case, we want to calculate the electric field just outside the paint layer: this means that we take r as the radius of the plastic sphere, so

r=R=0.18 m

The charge contained within the Gaussian sphere is therefore

q=-29.0 \mu C = -29.0\cdot 10^{-6}C

Therefore, the electric field is

E=\frac{q}{4\pi \epsilon_0 R^2}=\frac{-29.0\cdot 10^{-6}}{4\pi (8.85\cdot 10^{-12})(0.09)^2}=-3.2\cdot 10^7 N/C

And the negative sign indicates that the direction of the field is radially inward (because the charge that generates the field is negative). However, the text of the question says "Enter positive value if the field is directed radially inward and negative value if the field is directed radially outward", so the answer to this part is

E=3.2\cdot 10^7 N/C

C)

For this part again, we apply Gauss Law:

E\cdot 4 \pi r^2 = \frac{q}{\epsilon_0}

In this case, we want to calculate the field at a point 6.00 cm outside the surface of the paint layer; this means that the radius of the Gaussian sphere must be

r = 9 cm + 6 cm = 15 cm = 0.15 m

While the charge contained within the sphere is again

q=-29.0 \mu C = -29.0\cdot 10^{-6}C

Therefore, the electric field in this case is

E=\frac{q}{4\pi \epsilon_0 R^2}=\frac{-29.0\cdot 10^{-6}}{4\pi (8.85\cdot 10^{-12})(0.15)^2}=-1.2\cdot 10^7 N/C

And again, this is radially inward, so according to the sign convention asked in the problem,

E=1.2\cdot 10^7 N/C

Beryllium (Be) and fluorine (F) combine to make the compound BeF. What is the chemical name for this compound?
kvv77 [185]

Answer:

Option A

Beryllium fluoride

Explanation:

The combination of Beryllium (Be) and Fluorine (F) leads to formation of a compound called Beryllium fluoride (BeF). The name is changed to fluoride and not fluorine because the salts of fluorine are called fluoride salts. Beryllium has oxidation state of +2 being a metal with atomic number 4. Fluorine is the lightest halogen and known to be the most electronegative element due to its high affinity to attract electrons and it has atomic number 9. The combination of Be and F is a salt.

A pickup truck starts from rest and maintains a constant acceleration a0. After a time t0, the truck is moving with speed 25 m/s
Anastaziya [24]

Answer:

the correct answer is c     v₁> 12.5 m / s

Explanation:

This is a one-dimensional kinematics exercise, let's start by finding the link to get up to speed.

            v² = v₀² + 2 a₁ x

as part of rest v₀ = 0

           a₁ = v² / 2x

           a₁ = 25² / (2 120)

           a₁ = 2.6 m / s²

now we can find the velocity for the distance x₂ = 60 m

           v₁² = 0 + 2 a1 x₂

           v₁ = Ra (2 2,6 60)

           v₁ = 17.7 m / s

these the speed at 60 m

we see that the correct answer is c     v₁> 12.5 m / s

An electric radiator consumes 1500 W
vampirchik [111]

Answer:

Current = 6.82 A

Explanation:

Given the following data;

Power = 1500 Watts.

Voltage = 220 Volts.

To find the current;

Power = current * voltage

Substituting into the equation, we have;

1500 = current * 220

Current = 1500/220

Current = 6.82 Amperes.

Therefore, the current that traverses it is 6.82 Amperes.
