After a student shoves a book across a flat table, it begins to slow down. Why?
Answer:
The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down. When objects move through a fluid, such as air or water, the fluid exerts a frictional force on the moving object. The frictional force from a fluid is called a drag force.

What two forces propel the acceleration of change in human societies today?
Answer:
Collective behavior and social movements
Explanation:
Social movements are a collective behavior but are organized efforts and goal driven. It can range from local to national and can even reach globally. Groups that are behind social movements usually want to either create or resist social, political, economic, or cultural change.
The use of fossil fuels such as coal, oil, natural gas, and technical advancements in the contemporary age is driving the acceleration of change in human cultures today.
What are fossil fuels?Fossil fuels are obtained beneath the earth's crust, which is formed due to buried plants and animals. The excessive heat under the earth crust heats the plants and animals.
The use of fossil fuels such as coal, oil, natural gas, and technical advancements in the contemporary age is driving the acceleration of change in human cultures today.
Hence, the use of fossil fuels such as coal, oil, and natural gas, and technical advancements are two forces that propel the acceleration of change in human societies today

If you were to build a pipe organ with open-tube pipes spanning the range from 25 hz to 19 khz. The speed of sound in air is 343 m/s
Building a pipe organ with open-tube pipes spanning the range from 25 hz to 19 khz will require the length of the shortest pipe to be 0.018m
What is Length?This is defined as the measurement or extent of a substance from end to end. The formula is shown below:
L = v/f where v is speed , f is frequency
f1 = 25hz , f2 = 19khz
The length for both sides is seen below:
l1 = 343/25 = 13.72m
l2 = 343/19000 = 0.018m.
The length of the shortest pipe is therefore 0.018m.

The frequency of a repeated event is the number of occurrences per unit of time. The length of the shortest pipe is 0.018 m.
What is the frequency?The frequency of a repeated event is the number of occurrences per unit of time. It is also known as temporal frequency to distinguish it from spatial frequency, and ordinary frequency to distinguish it from angular frequency.
The formula of the length is given by the formula,
[tex]L=\dfrac vf[/tex]
where v is the velocity of the substance and f is the frequency.
Given that the speed of the sound in air is 343 m/sec, while the frequency is tanging from 25Hz to 19 kHz.
Therefore, the length of the pipe will be,
[tex]L=\dfrac vf\\\\L_1=\dfrac{343}{25} = 13.72\rm\ m[/tex]
[tex]L_2=\dfrac{343}{19 \times 1000} = 0.018\rm\ m[/tex]

How much force does the astronaut exert on his chair while accelerating straight up at 10.0 m/s2m/s2
Answer:
M a = Fc -M g
Use up as positive - a is the acceleration upwards
Fc = M (a + g) force exerted by chair
Fc = 19.8 M m/s^2 where M is the mass of the astronaut
The force exerted by the astronaut accelerating straight up with an acceleration of 10 m/s² is m/5 Newton.
What is force?If you want to accelerate a body of mass 'm' with acceleration 'a' than a force of magnitude given by the product of mass and acceleration is needed.
Given is an astronaut accelerating straight up with an acceleration of 10 m/s².
Since the astronaut is moving in upward direction, the resultant resultant force is in upward direction. Now, assume that the force exerted by the astronaut on the chair is F[A]. The normal reaction force on the astronaut will also be same. Mathematically -
F[N] = F[A]
Now, we can write the resultant normal reaction force as -
ma - mg = F[N]
F[N] = m(a - g)
F[N] = m(10 - 9.8)
F[N] = m(0.2)
F[N] = m/5
F[A] = F[N] = m/5
where m is the mass of astronaut.
Therefore, the force exerted by the astronaut accelerating straight up with an acceleration of 10 m/s² is m/5 Newton.

Yes, it is possible for dogs to be grey
Explanation:
Whippets are gray and they are a type of dog
Answer: Like humans, dogs tend to go gray as part of their natural aging process.
Explanation: Just like us, humans, dogs tend to go gray as part of their natural aging process. And just like us, as dogs get older, the pigment cells responsible for color (specifically, melanin) stop being produced; this causes the strands to come out at a lighter shade, like gray or white.

Which change is an example of transforming potential energy to kinetic energy?
Answer:
Changing nuclear energy to radiant energy
Explanation:
Conversely, potential energy is a type of energy stored in an object, which can be converted to kinetic energy.
Nuclear energy is a type of potential energy because this energy is stored in the atomic nucleus.
In conclusion, changing nuclear energy to radiant energy is an example of transforming potential energy into kinetic energy.
Answer:
if you stand still, that's potential energy, and if you move that's kinetic energy.
Explanation:
When standing still, you aren't moving, which the potential energy now is enact, but if you move a muscle, even the tiniest one, it will cause a transformation into kinetic energy.

is decreased the dispersion will also decrease.
Scientists have organized all forms of energy into two types—kinetic and potential. Kinetic energy is the energy of motion, and potential energy is stored energy.
Raise the pendulum again. Carefully watch the Energy Graph on the left. It shows the amount of energy the pendulum has as it moves.
At the top of its swing, does the pendulum have kinetic energy or potential energy?
PLEASE HELP!
Answer:
Potential energy only
Explanation:
at the top of its swing the pendulum stops moving , (therefore it has no KINETIC energy) thus all of the energy is stored as potential energy.

What is ohm's law?At constant temperature, Ohm's law says that the current flowing through an electric circuit is directly proportional to the voltage
Also, the current flowing through an electric circuit is inversely proportional to the resistance in the electric circuit.
This means that the magnitude of voltage (potential difference) is significantly reliant on the value of current flowing through an electric circuit.
This formula expresses Ohm's law mathematically.
V=IR

V is the voltage is measured in volts.
I denote the current in amperes.

Knowing the direction of heat flow, explain why if you leave a hot bowl of soup out in the open on the countertop, it eventually gets cold. Where is the heat going?
The heat will flow towards the air surrounding the soup bowl and towards the countertop below the bowl.
Where does the heat go?We know that when two bodies of different temperatures there will be a flow of heat between the objects, from the hotter one to the colder one.
In this case, we have the bowl of soup as the hot object, and the ambient (the countertop, the air surrounding the bowl, etc) itself will be the cooler object.
Then the heat will flow towards the air surrounding the soup bowl and towards the countertop below the bowl.

Why does the law of conversion of mass make sense?
Explanation:
If u mix 1g of salt with 100 ml of water, both dissolves but at the same time the mass of the solution increases.
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants. The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction
Answer:
The law of conservation of mass was crucial to the progression of chemistry, as it helped scientists understand that substances did not disappear as result of a reaction as they may appear to do; rather, they transform into another substance of equal mass.
