Think of a scenario where an authoritarian leadership style would be beneficial. Explain. What are the reasons it would work wel
icang [17]

Answer:

Explanation:

A scenario in which an authoritarian leadership would be beneficial is in law enforcement in emergency cases (that has to do with public safety or national security) without the bureaucratic bottlenecks of the legislature and judiciary. For example, the recent coronavirus pandemic, authoritarian leaderships would find it easier to enforce the laws on wearing of masks and also prevent producers of personal protective equipment (PPE) from unreasonably inflating prices of there PPEs.

As explained above, it would work well because there will be no legislative bottleneck that will start a hearing at the expense of public safety neither will there be a court that will stall the process at the same expense.

The risks here is that businesses (in this case that of producing PPEs) may find it difficult to survive since the "tone" of the pricing of PPEs will now be determined by government. It may even hinder healthy business competition. It may also lead to production of substandard PPEs in order to generate enough profit (since the main aim of any business is to generate profit).

givi [52]

Answer:

d = 13 miles

Explanation:

Lets say the position of court house is origin in this case

her office is located at 4 miles west and 4 miles south of court house

so here we have coordinate of the office with respect to court house is given as

r_1 = (-4\hat i - 4\hat j)

now the position of her home is located at 1 miles east and 8 miles north of the court house

so the coordinates of her home is given as

r_2 = (1\hat i + 8 \hat j)

now the change in the position is given as the distance between office and home

d = r_2 - r_1

d = 5 \hat i + 12 \hat j

d = \sqrt{5^2 + 12^2} = 13 miles

Anna [14]

Answer:

200000 J

Explanation:

From the question given above, the following data were obtained:

Mass (m) of roller coaster = 1000 Kg

Velocity (v) of roller coaster = 20 m/s

Kinetic energy (KE) =?

Kinetic energy is simply defined as the energy possess by an object in motion. Mathematically, it can be expressed as:

KE = ½mv²

Where

KE => is the kinetic energy.

m =>is the mass of the object

V => it the velocity of the object.

With the above formula, we can obtain the kinetic energy of the roller coaster as follow:

Mass (m) of roller coaster = 1000 Kg

Velocity (v) of roller coaster = 20 m/s

Kinetic energy (KE) =?

KE = ½mv²

KE = ½ × 1000 × 20²

KE = 500 × 400

KE = 200000 J

Therefore, the kinetic energy of the roller coaster is 200000 J.
