Answer:
It is possible for neutral objects to become charged by rubbing them together due to friction. Electrons of one object transfer to the other resulting to more electrons in the object than its protons therefore leaving it as charged

A new air mass moves into an area. Which will most likely occur?(1 point)
The colder air mass rises, and there will be clouds and rain.
The warmer air mass rises, and there will be clouds and rain.
The warmer air mass rises, and there will be sunshine and a clear day.
The colder air mass rises, and there will be sunshine and a clear day.
Answer:
The warmer air mass rises, and there will be clouds and rain.
Explanation:
The less dense air mass will rise.
In the given scenario, the warmer air mass rises, and there will be clouds and rain. The correct option is B.
What is air mass?A large volume of air in the atmosphere that is mostly uniform in temperature and moisture is referred to as an air mass.
Air masses can travel thousands of kilometers across the Earth's surface and reach all the way to the stratosphere.
In the horizontal direction, air masses have fairly uniform temperature and moisture content but not uniform in vertical.
The temperature and humidity properties of air masses define them. The underlying surface properties where air masses originate determine their properties.
The warmer air mass rises as a new air mass moves into an area, causing clouds and rain.
Thus, the correct option is B.

If you are holding a book and you let go of it, why does it fall? Explain in terms of forces, potential energy, and kinetic energy.
Answer:
Let the mass of the book be "m", acceleration due to gravity be 'g", velocity "v" and height be "h".
Now if we are holding a book at a certain height (h), the potential energy will be maximum which is equal to mass×acceleration due to gravity× height (=mgh).
(Remember: kinetic energy=0)
Now we consider that the book is dropped, in this case a force will act downward towards the centre of the earth, Force=mass×acceleration due to gravity (F=mg). It is equal to the weight of the book.
While the book is falling, the potential energy stored in the book converts into kinetic energy and strikes the floor with the maximum kinetic energy=(1/2)×mass×velocity² (=1/2mv²).
(Remember: potential energy=0)
Due to the process the whole energy is conserved.
As potential energy decreases kinetic energy increases.
True or False:
Energy transfers forms.
False
True

In a binary ionic compound, the electrons are
Answer:
Transferred from one atom to another
Explanation:
In a binary ionic compound, the electrons are transferred from one atom to another, thus forming positive and negative charges on the respective atoms involved, and thereby creating electrostatic forces which thus form the ionic bond.

A ball was rolling downhill at 2 m/s. After 5s, it was rolling at 90 m/s. What is its acceleration?
Answer:
17.6 m/s²
Explanation:
Given:
[tex]v_{f}[/tex] = 90 m/s (final velocity)
[tex]v_{i}[/tex] = 2 m/s (initial velocity)
Δt = 5s (change in time)
The formula for acceleration is:
[tex]a_{avg}[/tex] = Δv / Δt
We can find Δv by doing
Δv = [tex]v_{f}[/tex] - [tex]v_{i}[/tex]
Replace the values
Δv = 90m/s - 2m/s
Δv= 88m/s
Using the equation from earlier, we can find the acceleration by dividing the average velocity by time.
[tex]a_{avg}[/tex] = Δv / Δt
[tex]a_{avg}[/tex] = [tex]\frac{88m/s}{5/s}[/tex]
acceleration = 17.6 [tex]m/s^{2}[/tex]

which energy change is caused by an endothermic chemical reaction
Answer:
In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products. If a chemical reaction absorbs as much energy as it releases, it is called isothermic—there is no net energy change

Human diversity means similarities among people. It's each of us in our rich and infinite indistinguishable features. True of false?
Answer:
False.
Explanation:
Human diversity means differences among people. Therefore, it's each of us in our rich and infinite indistinguishable features; this is basically the fundamental building block of culture. For example, a doctor might enjoy watching football and educational documentary programs while another enjoys listening to music and watching thriller movies.
Culture can be defined as the general way of life of a group of people living together in a particular location or society.
Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.
This ultimately implies that, culture are acquired and passed from one generation to another.
A cultural trait can be defined as the smallest characteristics of human activity (actions) that is mainly acquired socially and transmitted from one generation to another through various modes of communication. Thus, these unique behavioral informations or characteristics and beliefs acquired by people socially are transmitted from one individual or group of people to another.

Why would a flare be observed in visible light, when they are so much brighter in X-ray and ultraviolet light?
Answer:
Because it radiates a spectre of frequencies, this means that it radiates in a continuous range of frequencies, ones with more intensity (like x-ray and ultraviolet) and others with less intensity (like the visible light). While most of the radiation is not in the visible range, there still is a part of the radiation in the visible spectre. And while this part is not the most intense part, the radiation is so large that we can see a very bright visible light.
