Based on the compression of the spring and the speed, the following are true:
The factor by which the spring's potential energy is increased is = 4.The factor of increase in speed = 2.What is the factor of increase in potential energy?Potential energy is found as:
= 0.5k x (2 x compression²)
= 4 x 1/2kx²
The 4 shows that the potential energy increases by 4 times.
What is the factor of increase in speed?Initial speed is:
= x × √(k/m)
New speed will be:
= Compression factor x speed
= 2x × √(k/m)
The speed will therefore be increased by a factor of 2.

What is a difference between an authoritarian government and a democratic government brainly
Answer:
The difference between an authoritarian government and a democratic government is that the authoritarian government has complete power/ownership over the country and everyone within the country, while a democratic government the government has very limited power divided in three branches while the citizens choose who gets elected to be in high power on their behalf.
Explanation:
Authoritarian government is on the basis of authority. The leaders of the government control every central part of the government and make changes to the country without its citizens consent or say. Authoritarian government is a very risky/evil form of government because it gives the leaders of the government complete control over every aspect of a person's life that's including entertainment, (by restricting their citizens from different forms of entertainment such as video games) social, (controlling their beliefs and what they feel is wrong or right) and financial which is by limiting how much of THEIR OWN money they can have/spend.
A common example of an authoritarian government would be Russia. Russian citizens do not have a say in what the country does and that is including war. Which is why will see many anti-war protests from Russian citizens during these times, you will also see them getting arrested for these protests. Entertainment, social, and financial control over a group of people's lives is authoritarian.
Democratic government is basically where the citizens of the country have a complete say in who becomes an elected official for their country. Common example of a democratic government is America. People in America choose who makes the decisions on behalf of them in government and Americans even have legislatures in place to make sure the government doesn't get too much power like separation of powers or checks and balances which divides the power between the three branches of government and the citizens are the ones who vote in the elected officials who will run these three branches of government.
They're many differences between an authoritarian government and a democratic government, so I will sum the complete different between the two in one statement. "The difference between an authoritarian government and a democratic government is that the authoritarian government has complete power/ownership over the country and everyone within the country, while a democratic government the government has very limited power divided in three branches while the citizens choose who gets elected to be in high power on their behalf."

The number of different combinations can she choose is; 210.
What is the permutation?
We are told that;
Number of colors of Lanyards she has = 7
Number she wants to use to make a key chain = 3 colours
Thus, number of different combinations can she choose is gotten through permutation formula;
P(n, r) = n!/(n - r)!
P(7, 3) = 7!/(7 - 3)!
P(7, 3) = 210
Thus, the number of different combinations can she choose is 210.

The probability of the sample mean in each of the given options are respectively; 0.8884 and 0.9934
What is the Probability?We are given from online complete question;
Mean; µ = 300
Standard deviation; σ = 70
Sample size; n = 125
A) For the sample to be within 8 units of the population mean, we would have sample values of 292 and 308. Thus, the expression is;
P(292 < x < 308).
z-score here is;
z = (292 - 300)/(70/√125) or z = (308 - 300)/(70/√125)
z = -1.28 or 1.28
From online p-value from z-score calculator, the p-value is 0.8884.
B) For the probability of the sample mean to be within 17 units of the population mean, we need to find the values from 283 to 317. We want to find P(283 < x < 317).
The z-scores here are;
z = (283 - 300)/(70/√125) or z = (317 - 300)/(70/√125)

Answer:
Displacement is the word we use for the distance covered so in this case when a car travels 20 meters east in 1 second, at the end of that 1-second interval a car travels a distance of 20 meters.
And the distance covered is the displacement, so it means that displacement of the car after 1 second is 20 meters east.
One of the most important characteristics of the water molecule is its _____, which allows it to surround and attract both positive and negative ions.
Answer:
Polarity
Explanation:
Covalent bonds may be either polar or nonpolar. Polar molecules, such as water, are asymmetric molecules that have unbalanced electronegativity, leading to slight charges on the atoms within the molecule.
Water's polarity
The chemical equation for water is [tex]H_20[/tex]. In this molecule, oxygen has 2 unbonded electron pairs. This causes the molecule to have a bent geometry. Bent molecules are always polar due to the dipoles formed by the unshared electron pairs. These dipoles create a slight negative charge on the oxygen atom and a slight positive on the hydrogen atoms.
Intermolecular Forces
Due to the slight charges of a water molecule, the oxygen molecules attract positive ions, and the hydrogen atmos attract negative ions. This interaction is known as an ion-dipole intermolecular force (IMF).
Answer:
Polarity
Explanation:
Polarity in a substance or molecules arises when the two combining atoms have different electronegativities. As more electronegative atoms will attract the electrons from electropositive atoms toward itself.
Due to this, there will be development of partial positive charge on electropositive atoms and a partial negative charge on the electronegative atoms.
For example, in water (H₂O) due to the difference in electronegativities of the hydrogen and oxygen atoms, there is a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom.
Due to these charges it is able to attract ions of opposite charges that are surrounding.
Thus, we can conclude that one of the most important characteristics of the water molecule is it's polarity, which allows it to surround and attract both positive and negative ions.

Answer:

The pulley in the figure (figure 1) has radius r and a moment of inertia i. The rope does not slip over the pulley, and the pulley spins on a frictionless axle. The coefficient of kinetic friction between block a and the tabletop is μk. The system is released from rest, and block b descends. Block a has mass ma and block b has mass mb
The speed of block B in terms of the distance (d) it has descended is [tex]V=\frac{2gd(m_B-\mu_k m_A)}{m_A \;+\; m_B \;+\;\frac{I}{r^2}}[/tex]
How to determine the speed.In order to determine the speed of block B in terms of the distance (d) it has descended, we would apply the work-energy theorem as follows:
[tex]Work=\Delta KE=KE_f-KE_i[/tex]
The work done due to gravity is given by:
[tex]W_g=(m_B)gd[/tex]
The work done due to friction is given by:
[tex]W_f=-\mu_k (m_A)gd[/tex]
The angular velocity of pulley is given by:

Applying the work-energy theorem, we have:

How vocation stress may negatively affect your family
Explanation:
Vocational stress refers to the stress caused because of one’s professional settings. It can be caused because of a number of reasons, like the fear of losing one’s job, working overtime, not getting credit for one’s efforts, being pushed to meet unrealistic targets, being blamed unfairly, not getting along with the boss or colleagues, or being forced to compromise with one’s honesty. In any case, vocational stress causes feelings of fear and anxiety, which greatly affects family life.
A high degree of stress or anxiety makes one irritable and impatient. The person becomes unpredictable and easily loses his/her temper with family members. Tantrums become common and the rest of the family start avoiding the individual. A disconnect starts setting in, pushing him/her further into depression. This leads to a lack of confidence and eventually with growing frequency of arguments, family life does not remain peaceful.
