Boss tweed encourage his associates to work like a well oiled machine thus providing his workers with benefits that encourages them to work like a well oiled machine. A well oiled machine means that it does not stop, its work is continuous and efficient.

Answer:

A. an analogy

Explanation:

Page 90 of 150 PF Downloaded Lesson:

Analogies are representations that help in understanding a problem, a

set of circumstances, or even an unfamiliar object. In using an

analogy, you might compare something you’re familiar with to

something you’re less certain about in an attempt to understand the

unfamiliar thing. Or you may form an analogy to make a concept clear

to someone else. For example, to give employees an idea of what’s

expected of them, a supervisor might refer to a good department as “a

hive of busy bees.” To help the people you supervise get an idea of

the mental attitude you would prefer they adopt, you could refer to a

clear, sparkling mountain stream as an analogy of an open, flowing

mind—nothing hidden at the bottom, always moving toward new

destinations and new ideas.

A solid steel sphere of density 7.86 g/cm3 and mass 1 kg spin on an axis through its center with a period of 2.3 s. given vspher

Alenkasestr [34]

The solution for this problem is:

density = mass / volume 
7860 = 1 / ((4/3) pi r^3)
r^3 = 1 / (7860 * 4/3*pi)
r = (1 / (7860 * 4/3*pi))^(1/3)

= 0.067 m 

Inertia = (2/5)mr^2

= (2/5) x 1 x 0.067^2

= 0.0017956 kg-m^2 

1/2.3 = 0.4348 rev/s

0.4348 x 2pi = 2.732 rad/s

Angular momentum = Inertia x rad/s

0.0017956 x 2.732 = 0.00490557 kg m^2/s

Hypothesis:

SIZIF [17.4K]

Answer:

1.) Wavelength

2.) Number of fringes

Explanation:

1.) If we split a laser beam by using a diffraction grating slide, then we can

verify the wavelength by applying the formula λ = ds/l.

2) If we split light into its individual wavelengths using a diffraction grating,

then we can determine the number of fringes by multiplying the spacing of the gradient lines (d) times the distance to the central maxima of the color band (s) divided by the length distance from the grating slide to the screen (l).

Which scenario presents a possible environmental impact due hydrogen fuel cells?

Mekhanik [1.2K]

The scenario that presents a possible environmental impact due to hydrogen fuel cells is that, the electricity used to supply the fuel cells with Hydrogen is produced using fossil fuels.

The question is incomplete, but these should have been the options;

a.) The fuel cells are used to power internal combustion engines rather than electric motors.

b.) The electricity used to supply the fuel cells with hydrogen is produced using fossil fuels.

c.) The combined exhaust emissions from fleets of buses equipped with fuel cells generates smog.

d.) None of these are correct.

The answer therefore is option B. The Hydrogen fuel cell is a device that uses Hydrogen as an energy source to power machines and to generate heat and electricity. It is a green energy alternative to fossil fuels as unlike fossil fuels, it doesn't produce green house gases and is non-toxic. Also, unlike other clean sources of energy like wind and water, it doesn't require a large area of land to be produced.

Hydrogen fuel cells work by combining hydrogen and oxygen atoms. The resulting energy produced is converted to electrical energy which can be used to power electrical motors, while the by-product, water is non-toxic, renewable and doesn't create smog.

However, to produce the hydrogen used in the cells, high amount of energy is required in order to separate hydrogen from oxygen. To accomplish this, fossil fuels such as coal, natural gas and oil are used, releasing harmful emissions which creates a negative environmental impact. This makes the answer to the above question option B. A better alternative though, is to use other renewable energy sources like wind or solar.

A certain satellite has a kinetic energy of 7.5 billion joules at perigee (closest to Earth) and 6.5 billion joules at apogee (f

Elena L [17]

Answer:

Work Done by the earth's gravitational force on the satellite as it travels from apogee to perigee is

W = F*D*Cos90° = 0

Explanation:

Although there is a change in the kinetic energy of the satellite at the apogee and perigee, the work done by the earth's gravitational force on the satellite is Zero.

W = F.D, F is the gravitational force, D is the displacement. Both F and D are vectors and perpendicular to each other. That is, the angle between F and D is 90°.

Semmy [17]

Answer:

2.68 hours

Explanation:

A.) Suppose the wind blows out from the west (with the air moving east). The pilot should then head her plane to northwest direction to move directly north.

B.) Given that plane flies at a speed of 102 km/h in still air. And the wind blows out from the west (with the air moving east) at a speed of 46 km/h.

The plan resultant speed can be calculated by using pythagorean theorem.

Resultant Speed = Sqrt( 102^2 + 46^2 )

Resultant Speed = Sqrt( 12520)

Resultant speed = 111.89 km/h

From the definition of speed,

Speed = distance/time

Where distance = 300 km

Substitute the resultant speed and the distance into the formula.

111.89 = 300/time

Time = 300/111.89

Time = 2.68 hours

Therefore, it take her 2.68 hours to reach a point 300 km directly north of her srarting point
