In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

Which best describes two counteracting forces on an object?
using a dolly to push a box to another location
two children pulling apart a wishbone
a group of dogs pulling a dogsled across ice
two people pushing a broken-down car up the road
Answers
Answer: B) two children pulling apart a wishbone
One person is on the left side, and the other person is on the right side. They pull in opposite directions to separate the bone. These forces counteract each other since they go in opposite directions.
In contrast, each of choice A, C, and D describe one or more forces that work together to go in the same direction. This could be a pulling force, or a pushing force, it doesn't matter either way. We can rule out choices A,C, and D for this reason.

What is the Charles law?The Charles, Boyle's and Gay - Lussac's laws are applied here.
We know that;
From Gay Lussa law
\(P_{1}\)/\(T_{1}\) = \(P_{2}\)/\(T_{2}\)
\(P_{2}\) = 1.21 * 450/315
\(P_{2}\) = 1.72 atm
From Charles's law
\(V_{1}\)/\(T_{1}\) = \(V_{2}\)/\(T_{2}\)
\(T_{2}\) = 4.8 * 495/2.7
\(T_{2}\)= 880 k
From Boyle's law
\(P_{1}\)\(V_{1}\)= \(P_{2}\)\(V_{2}\)
\(P_{2}\) = 7.14 * 1.9/12.0
\(P_{2}\) = 1.13 atm
From the general gas law;
\(V_{2}\) = 2.1 * 6.9 * 291/1.8 * 400
\(V_{2}\) = 4216.59/720
\(V_{2}\) = 5.9 L
From Gay Lussa law
\(P_{1}\)/\(T_{1}\) = \(P_{2}\)/\(T_{2}\)
\(P_{2}\) = 315.2 * 145/273
= 167.4 kPa

Why is it easier for most metal elements to gain electrons rather than to lose them?
PROPER EXPLANATION
Answers
Because it is easier for metals to shed their valence electrons and form cations for a stable configuration, they have comparatively few chances of acquiring electrons.
The metals usually complete their octet in each reaction. The outermost electron shell often contains more electrons in metals. Metal atoms lose electrons when they interact with other non-metals because the energy of an electron in its outermost shell is very weak.
Metals often have low ionization energy because their electrons are positive in nature. Metals lose their electrons and trade them with non-metals to achieve a stable configuration.

your alien friend from planet xenon is visiting and wants to learn how to breed pea plants you show your friend a recent batch of pea plants with purple flowers that you grew by crossing plants that had purple flowers with plants that had white flowers your friend is confused as to why your plants all have purple flowers how would you explain in the simplest way possible what happened
Answers
Answer:
The purple flowers were probably was dominate allel and the white flowers were recessive.
Explanation:
When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answers
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
kinetic energy is given as
5) when speed is 6 m/s
kinetic energy is given as

A water molecule takes a journey that includes a cloud, mountain, atmosphere, lake, and groundwater. Write a scientific explanation about the directions the water molecule would move and what causes it to move through the cycle. (Must use CER!) (Finish it immediately!)
Answers
Answer:
Claim: A water molecule moves through the water cycle in a continuous journey that involves changes in state and location.
Evidence: The journey of a water molecule begins when it evaporates from a body of water, such as a lake or the ocean, due to the energy from the sun. The water molecule rises into the atmosphere and joins other water molecules to form a cloud. As the cloud moves, it may pass over a mountain and cool, causing the water molecules to condense into liquid or solid form and fall as precipitation. Some of the precipitation may fall into a lake or river, where it can flow downstream and eventually enter the groundwater system. The water in the groundwater system may eventually resurface in a lake or river, or it may be extracted from a well for human use.
Reasoning: The movement of a water molecule through the water cycle is driven by a combination of physical and chemical processes, including evaporation, condensation, precipitation, and infiltration. The sun provides the energy that drives the cycle, causing water to evaporate and rise into the atmosphere. As the water molecules cool, they may condense into clouds and eventually fall as precipitation. The movement of water through the cycle is also influenced by factors such as temperature, pressure, and gravity. For example, water will flow downhill due to gravity, which can cause it to move through the groundwater system and eventually resurface in a lake or river. Overall, the water cycle is a complex and continuous journey that is essential for maintaining the Earth's water supply and supporting life.

What is the meaning of environmental issues?Environmental issues are defined as harmful effects to Earth and its natural systems due to the actions of humans.
The food supply chain and restaurant customer experience generate a lot of waste – from food waste to plastic waste, and more. Unfortunately, one-third of the world's food gets wasted. This waste alone amounts to 8% of the world's greenhouse gas emissions.
