Nostrana [21]3 years ago
7 0

Answer:

1. authority - power to enforce laws

2. unalienable - something that cannot be taken away

3. declaration - a forceful statement

4. self-government - the right to govern oneself

Explanation:

1. Authority- power to enforce laws

<u>It is the power that is being practice by either a person or a group of people over their subjects. </u>The person uses this power<em> in order to cause an action.</em> For example, the CEO of Mitsubishi will decide on what supply manufacturer they will choose. This means that he has the authority over this area. He does this in order for the company to achieve its organizational goal more efficiently.

2. Unalienable -  This is also synonymous to the term "inalienable."

<u>This is something that cannot be taken away from a person, such as the right to live, to have liberty and to find happiness.</u> This is a popular term used in the "Declaration of Independence," in which American colonists disclosed their grievances under King George III in order to attain independence. This right cannot be revoked or transferred, nor is it negotiable.

3. Declaration - t<u>his is a forceful statement or an announcement of something that is deemed important. </u>This also considered an official statement and is disclosed to public for an intended purpose. Regarding specific cases, a declaration refers to stating the facts that serves as a ground to support the case. It can includes many sections that explains the reasons why actions were made.

4. Self-government -<u> </u><u>this is the ability of a person or group to do things on their own or have control without the influence or authority from outside. </u>When it comes to economy, this refers to the rule of the people. This can also be practiced in school, whereby students participate in making the school laws and enforcing them as well. This is a common characteristic for democratic countries where people has a say in the society.

An airplane is seller rates down a runway at 3.10 M/S squared 441.5 seconds from rest until finally left off the ground ,what is
sineoko [7]

Answer:

302129m

Explanation:

Using s= ut + 1/2at²

But u= 0

So

S= 1/2(3.1)(441.5)²

=302129m

A 0.20 kg mass on a horizontal spring is pulled back a certain distance and released. The maximum speed of the mass is measured
xxMikexx [17]

Answer:

b. 0.20 m/s.

Explanation:

Given;

initial mass, m = 0.2 kg

maximum speed,  v = 0.3 m/s

The total energy of the spring at the given maximum speed is calculated as;

K.E = ¹/₂mv²

K.E = 0.5 x 0.2 x 0.3²

K.E = 0.009 J

If the mass is changed to 0.4 kg

¹/₂mv² = K.E

mv² = 2K.E

v = \sqrt{\frac{2K.E}{m} } \\\\v =  \sqrt{\frac{2\times 0.009}{0.4} } \\\\v = 0.21 \ m/s\\\\v \approx 0.20 \ m/s

Therefore, the maximum speed is 0.20 m/s

A 54.0 kg ice skater is gliding along the ice, heading due north at 4.10 m/s . The ice has a small coefficient of static frictio
lesya [120]

Answer:

a. 2.668 m/s

b. 0.00494

Explanation:

The computation is shown below:

a. As we know that

W = F\times d

KE = 0.5\times m\times v^2

As the wind does not move the skater to the east little work is performed in this direction. All the work goes in the direction of the N-S. And located in that direction the component of the Force.

F = 3.70 cos 45 = 2.62 N

W = F \times d = 2.62 N \times 100 m

W = 261.6 N\times m

We know that

KE1 = Initial kinetic energy

KE2 = kinetic energy following 100 m

The energy following 100 meters equivalent to the initial kinetic energy less the energy lost to the work performed by the wind on the skater.

So, the equation is

KE2 = KE1 - W

0.5 m\times v2^2 = 0.5 m\ v1^2 - W

Now solve for v2

v2 = \sqrt{v1^2 - {\frac{2W}{M}}}

= \sqrt{4.1 m/s)^2 - \frac{2 \times 261.6 N\times m}{54.0 kg}}

= 2.668 m/s

b. Now the minimum value of Ug is

As we know that

Ff = force of friction

Us = coefficient of static friction

N = Normal force = weight of skater

So,

Ff = Us\times N

Now solve for Us

= \frac{Ff}{N}

= \frac{3.70 N \times cos 45 }{54.0 kg \times 9.81 m/s^2}

= 0.00494
