Complete the statement below about developing technology responsibly.
To develop technology responsibly, people must evaluate both the ____________ and the____________ consequences of the technology
Answer:
Positive & negative
Explanation:
To develop technology responsibly, people must evaluate both the immediate and the long-term consequences of the technology.
This entails considering not only the short-term benefits and potential gains but also the potential risks, ethical implications, and broader societal impacts that the technology may introduce. Responsible development requires a comprehensive analysis of how the technology could affect individuals, communities, economies, and the environment. Striking a balance between innovation and accountability is essential to ensure that the benefits of technology are maximized while minimizing any unintended harm. By thoroughly examining both the immediate and long-term consequences, developers can make informed decisions that prioritize the well-being of all stakeholders and foster a more sustainable technological landscape.

A bicyclist is traveling at +25m/s when he begins to decelerate at -4m/s2. How fast is he traveling after 5 seconds
Answer:
+5m/s
Explanation:
When doing the math we figure out that e is going to be slowing down at -4m/s² for 5 seconds. In total he is slowing down -20m/s which we take from the total speed of +25m/s to get his current new speed.
The Big Bang theory is closely linked to Hubble's discovery that the universe is expanding, which seems to imply that there was a time in the past when the expansion first began. Nevertheless, the Big Bang theory did not gain widespread acceptance among scientists until the 1960s. Why wasn't expansion alone enough to convince scientists that the Big Bang really happened
Answer:
Although expansion seems to imply a Big Bang, no other specific predictions of the Big Bang theory were tested and confirmed until the 1960s.
Explanation:
Answer:
Today, the consensus among scientists, astronomers and cosmologists is that the Universe as we know it was created in a massive explosion that not only created the majority of matter, but the physical laws that govern our ever-expanding cosmos. This is known as The Big Bang Theory. For almost a century, the term has been bandied about by scholars and non-scholars alike. This should come as no surprise, seeing as how it is the most accepted theory of our origins.

Write the importance of international bureau of weight and measures in the country
Answer:
International Bureau of Weights and Measures (BIPM) is an international organization founded to bring about the unification of measurement systems, to establish and preserve fundamental international standards and prototypes, to verify national standards, and to determine fundamental physical constants. The bureau was established by a convention signed in Paris on May 20, 1875, effective January 1876. In 1921 a modified convention was signed. The convention provides for a General Conference that meets every four years to consider required improvements or modifications in standards. An International Committee of Weights and Measures, composed of 18 scientists elected by the conference, meets annually to monitor worldwide uniformity in units of measure.

If you want to find out the density of an object, what two things do you need to know about it?
Answer:
How do I determine density? Density is not something that is directly measured. Typically if you want to know the density of something you will weigh it and then measure its volume.

Which statement correctly compares the valence electrons for atoms of francium (Fr) and barium (Ba)?
(1 point)
Francium has more valence electrons, and they are in a higher energy level.
Barium has fewer valence electrons, but they are in a higher energy level.
Barium has more valence electrons, and they are in a higher energy level.
Francium has fewer valence electrons, but they are in a higher energy level.
From the Periodic Table...
Francium is a group 1 Element and Barium is a Group 2 Element
This statement is a giveaway as it already tells you that Barium has more valence electrons than Francium since it has 2 electrons in its Outer shell.
This Eliminates Options A and B
Francium has more electrons than Barium
So It should be at a higher energy level.
The correct statement is Francium has fewer valence electrons, but they are in a higher energy level.
The energy level of an element is the region of space around the nucleus where its electrons are found. This corresponds to the period of the element in the periodic table.
Francium is in period 7 in the periodic table (in energy level 7)Barium is in period 6 in the periodic table (in energy level 6)in the electronic configuration of Francium, the valence electron is in 7s¹in the electronic configuration of Barium, the valence electron is in 6s²Thus, we can conclude that, Francium has fewer valence electrons, but they are in a higher energy level.

Define upstroke and downstroke?
Answer:
The upstroke is a mechanism that helps to raise the plunger and downstroke helps to help lower the plunger. On the up-stroke of the plunger, the lower valve opens and the upper valve is closed. Whereas, on the downstroke, the lower valve closes and the upper one opens.

According to the law of conservation of matter, we know that the total number of atoms does not change in a chemical reaction and thus mass is conserved. The reactant in this model is hydrogen peroxide. Hydrogen peroxide decomposes to produce water and oxygen gas. How many water molecules must be added to complete this model?
Answer:
In a chemical reaction the total mass of all the substances taking part in the reaction remains the same. Also, the number of atoms in a reaction remains the same. Mass cannot be created or destroyed in a chemical reaction.

Why heavy vehicles usually have low velocity but possess high kinetic energy
The kinetic energy is high because, the mass of the object is large and thus has a great momentum and its velocity low because it has a large mass.
We know that kinetic energy of an object K = 1/2mv² where m = mass of the object and v = velocity of the object and its momentum, p = mv
For a given value of kinetic energy, the mass of the object m = 2K/v². This implies that m ∝ 1/v².
So, as the mass of the object increases, its velocity decreases.
So. an object with large mass has low velocity while an object with small mass has high velocity.
Also, the kinetic energy, K = 1/2mv². So, K ∝ mv². So, if m is large and v is small, the product mv² is large and thus K = 1/2mv² is high.
So, the kinetic energy of heavy vehicles is high because, the mass of the object is large and thus has a great momentum and its velocity low because it has a large mass.

Group 2 elements have two valence electrons. Which kind of bond will they most likely form, and why?(1 point)
A covalent bond is likely because they want to share those two valence electrons in order to become stable.
An ionic bond is likely because they will want to give away two valence electrons in order to become stable.
An ionic bond is likely because they are metals and will want to bond with nonmetals.
A metallic bond is likely because they are metals and can bond with other metals.
Answer:
An ionic bond is likely because they will want to give away two valence electrons in order to become stable.
Considering the octet rule and the definition of ionic bond, the correct option is the second option: "An ionic bond is likely because they will want to give away two valence electrons in order to become stable."
Consider first the octet rule, which states that atoms combine or form ions with the goal of obtaining 8 electrons at their last level. In this way, an electronic configuration similar to that of the closest noble gas in the periodic table is reached. This happens because this configuration, of full electronic level, is very stable from the energy point of view
On the other hand, an ionic bond is a type of chemical bond that occurs when one atom gives up an electron to the other, in order for both to achieve electronic stability.
This union normally occurs between metal and nonmetal elements with different electronegativity, which means that the elements have different capacity to attract electrons. In general, metal elements are willing to donate an electron while nonmetals are willing to receive it.
In summary, an ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.
Finally, the correct option is the second option: "An ionic bond is likely because they will want to give away two valence electrons in order to become stable."
