Answer:

A. It sought to justify the divine right of kings

Explanation:

The Age of Enlightenment or the Enlightenment period was a period of the intellectual and the philosophical movement which dominated in Europe in the world of ideas during 17th and the 18th centuries.

The Enlightenment philosophers of that time greatly influenced the founders of the American government as they provided a government with consent, the idea of the natural rights of its people,etc.

The Protestant theory of the social contract conflicted with divide rights of the kings which was a catholic idea.

Thus option (A) is correct.

An airplane propeller is 2.68 m in length (from tip to tip) and has a mass of 107 kg. When the airplane's engine is first starte
telo118 [61]

Answer:

a)30.14 rad/s2

b)43.5 rad/s

c)60633 J

d)42 kW

e)84 kW

Explanation:

If we treat the propeller is a slender rod, then its moments of inertia is

I =\frac{mL^2}{12} = \frac{107*2.68^2}{12} = 64.04 kgm^2

a. The angular acceleration is Torque divided by moments of inertia:

\alpha = \frac{T}{I} = \frac{1930}{64.04} = 30.14 rad/s^2

b. 5 revolution would be equals to 10\pi rad, or 31.4 rad. Since the engine just got started

\omega^2 = 2\alpha\theta = 2*30.14*31.4 = 1893.5

\omega = \sqrt{1893.5} = 43.5 rad/s

c. Work done during the first 5 revolution would be torque times angular displacement:

W = T*\theta = 1930 * 31.4 = 60633 J

d. The time it takes to spin the first 5 revolutions is

t = \frac{\omega}{\alpha} = \frac{43.5}{30.14} = 1.44 s

The average power output is work per unit time

P = \frac{W}{t} = \frac{60633}{1.44} = 41991 W or 42 kW

e.The instantaneous power at the instant of 5 rev would be Torque times angular speed at that time:

P_i = T*\omega = 1930*43.5=83983 W or 84 kW

an ice cube is placed in the sun later there is a puddle of water later still the.puddle is gone what kind of change has occured
TiliK225 [7]

Clear question is;

An ice cube is placed in the sun. Later there is a puddle of water. Later still the puddle is gone. What kind of change has occurred?

Answer:

Physical change.

Explanation:

There are two type of changes called physical change and chemical change.

In Physical changes, there is only change in the appearance of the substance and not its chemical composition. Whereas, in Chemical changes the substance changes entirely into another substance with a new chemical formula.

Now, for the ice cube, it has melted from a solid state to a liquid state. Thus, there is only a change in appearance and not its chemical composition. Thus, it's a physical change that has occurred.

10. A book has a mass of 400 g. The surface of the book in contact with a table has dimensions 0.10m x 0.20 m. The gravitational
morpeh [17]

The pressure exerted on the table due to the book is 200 N/m².

The given parameters;

  • <em>mass of the book, m = 400 g = 0.4 kg</em>
  • <em>dimension of the table,  = 0.10m x 0.20 m.</em>
  • <em>gravitational field strength g =  10 N/kg.</em>

The area of the table is calculated as follows;

A = 0.1 x 0.2 = 0.02 m²

The pressure exerted on the table due to the book is calculated as follows;

P = \frac{F}{A}

where;

  • <em>F is the force of the book due to its weight</em>

<em />

P =\frac{F}{A} = \frac{mg}{A} = \frac{0.4 \times 10}{0.02} = 200 \ N/m^2

Thus, the pressure exerted on the table due to the book is 200 N/m².
