A hollow sphere (of negligible thickness) with no load, with a radius of 8.00 cm, surrounds a charge of 20.00 μC located at the

origin of a Cartesian coordinate system. A 2.00 mm radius drill is aligned along the Z axis and a hole is made on the surface of the sphere. Calculate the electrical flow through the borehole.
a

39.3 N*m2/C

b

17.7 N*m2/C

c

587 N*m2/C

Answer:

The electrical flow through the borehole is 353 Nm²/C.

(e) is correct option.

Explanation:

Given that,

Radius = 8.00 cm

Charge = 20.00 μC

radius of drill = 2.00 mm

We need to calculate the electrical flow through the borehole

Using formula of electric flow

\phi=EA

\phi=\dfrac{kq}{R^2}\times\pi\times r^2

Where, q = charge

R = radius of sphere

r = radius of drill

Put the value into the formula

\phi=\dfrac{9\times10^{9}\times20\times10^{-6}}{(8\times10^{-2})^2}\times\pi\times(2.00\times10^{-3})^2

\phi=353\ Nm^2/C

Hence, The electrical flow through the borehole is 353 Nm²/C.

An empty container has a mass of 3 g. When it is filled with 5 cm3 of a liquid,
IrinaK [193]

Answer:

THE MASS OF THE LIQUID IS 22.5 g

Explanation:

Density = 0.180 g/cm3

Side length = 5 cm

Mass = unknown

To calculate the mass of the liquid, we use the formula:

Mass = density * volume

Volume of a cube or cuboid container = l^3

Volume = 5 ^3 = 125 cm3

So therefore, the mass of the liquid is:

Mass = 0.180 * 125

Mass = 22.5 g

In conclusion, the mass of the liquid in the container is 22.5 g

Which of the following maxims would apply to a person with a Type A personality?
lozanna [386]

The correct answer is C. Lost time is never found again

Explanation:

One of the most relevant personality theories is Type A and Type B personality theory that proposes two main types of personalities by grouping different personality traits. In the case of Type A personality, this refers to individuals that are very organized, impatient, and concerned with time and goals. On the opposite, Type B personality includes individuals that are more relaxed in different aspects.

According to this, one maxim that applies to Type A personality is "Lost time is never found again" because people with this personality are concerned about time and therefore, loss of time is considered highly negative by them. Also, due to their ambitions and concern with goals they want to avoid losing time as this is equivalent to work, money, goals, etc.
