Which drum would make a sound that fades away faster - one that makes a loud sound or one that makes a more mellow sound Why?
Answers
Answer: one that makes a more mellow sound
Explanation:
One that makes a more mellow sound will have a constant frequency than the one that has a loud sound.
Fading away of sound waves depends on the wavelength of the sound. The one that has a loud sound with high frequency will have a brighter sound. While the more mellow one will have the bassier sound. Therefore, the sound with a more mellow sound will fade away faster.
Describe 3 factors an engineer should take into consideration when choosing material for building the pipes in a pipeline
Gr. 8
Think it has something to do with Viscosity, Density, and Pressure but not sure what
Answers
Answer: 1. Material being transported 2. The temperature of the material being transported 3. How long the pipes will be there (lifespan)
Explanation: 1. - The pipe builder should consider the material being transported to choose the correct material of the pipes to use, so they last long and can hold the material.
2. - Similar to 1, the pipe builder should consider the temperature of the material to choose the correct material of the pipes to use, so the pipes don’t break and function properly.
3. - If the pipe builder uses a material that can hold the material, that’s great! If that material will last a short time, it would not work if the pipes were to be used for a long time.
The things you said before about viscosity, density, and pressure are also correct. The correct answers are mainly talking about factors of the material being used in the pipes.

The table provided shows data collected during an experiment:
Which of the following claims is supported by the data?
A: Gravitational Forces are proportional to the masses of the two objects
B: Gravitational Forces are strongest between objects with identical masses
C: Gravitational Forces are weakest when one object is more massive than the other
D: Gravitational Forces can never exceed an upper limit, regardless of masses
Answers
As per the given table, Gravitational Forces are proportional to the masses of the two objects. The correct option is A.
Because the gravitational forces are not always the strongest between objects of the same mass, the evidence does not support assertion B.
Since the gravitational forces do not always correlate with one item being more massive than the other, the data does not strongly support argument C either. For instance, despite having two distinct masses, the first entry has a higher force.
The facts also do not support Claim D since there are circumstances in which the gravitational force surpasses predetermined upper bounds.
As gravitational forces typically increase with object mass, Claim A is the one that best fits the evidence.
Thus, the correct option is A.

How many kW*h (kilowatt hours) of electricity is consumed by a 500 w light bulb that burns
for seven hours?
Answers
Answer: 3.5 kWh
Explanation:
Given that the
Power P = 500 W
To convert watt to kilowatt, divide it by 1000
Power P = 500/1000 = 0.5 kw
Time t = 7 hours
Power is the rate at which work is done. That is,
P = WD/t
Cross multiply
WD = Pt
Where workdone WD is the energy E consumed in kWh .
Substitute P and t in the formula above.
E = 0.5 × 7
E = 3.5 kWh
Therefore, 3.5 kWh (kilowatt hours) of electricity is consumed by a 500 w light bulb that burns.

In a recent hockey game, one player (m=100kg) was moving at a velocity of 8 m/s when he ran into another player (m=300kg) who was at rest (v=0m/s). After the collision, the two players were stuck together (moving with the same velocity). What was their velocity after the collision?
Answers
Buttttttttttt if they were at rest because the force was balanced it could be
0m/s^2
Or the other way around
25m/s^2
Their velocity after the collision was 2 m/s.
What is principle of conservation of momentum?
According to the principle of momentum conservation, momentum is only modified by the action of forces as they are outlined by Newton's equations of motion; momentum is never created nor destroyed inside a problem domain.
Given parameters:
one player (m=100kg) was moving at a velocity of 8 m/s initially.
Another player (m=300kg) who was at rest (v=0m/s) initially.
After collision they stuck together and let the velocity of them is v.
According to principle of conservation of momentum, total momentum remains conserved.
total initial momentum = total final momentum
100×8 + 300×0 = (100 + 300)v
400v = 800
v = 2.
Hence, their velocity after the collision was 2 m/s.

An astronomer writes down the following for an object in the night sky: azimuth 364˚ and altitude 93˚, what is wrong with the values?
Answers
If your azimuth is larger than 180 degrees, multiplying it by 180 degrees to find your rear azimuth will result in an azimuth that is greater than 360 degrees.
What azimuth 364˚, altitude 93˚, what is wrong with values?A circle has 360 degrees, thus if your azimuth is higher than 180 degrees, multiplying it by 180 degrees to find your back azimuth will result in an azimuth higher than 360 degrees.
Because many ancient calendars had 360 days, it may be because the stars appeared to rotate around the north star at a rate of around 1 degree every day that azimuth is measured using a 0-360° interval. Azimuth is utilized outside of astronomy in disciplines like navigation and geology.

What are the formulas for Newton's 1,2,3 laws of motion?
How did he come up with the idea of his book?
Answers
Newton's three laws of motion can be summarized by the following formulas:
Law of Inertia, Newton's 1st Law of motion:
F = 0, or F = ma if there is an acceleration.
This means that if an object is at rest, it will remain at rest unless acted upon by an external force. Similarly, if an object is in motion, it will continue to move in a straight line at a constant speed unless acted upon by an external force.
Newton's second law of motion:
F = ma
This formula states that the acceleration of an object is directly proportional to the net force applied to the object and inversely proportional to its mass. In other words, the greater the force applied to an object, the greater its acceleration will be. Similarly, the greater the mass of an object, the smaller its acceleration will be for a given force.
Newton's third law of motion:
FAB = -FBA
This formula states that for every action, there is an equal and opposite reaction. In other words, when one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.
Isaac Newton's most famous book, "Philosophiæ Naturalis Principia Mathematica" (often called "the Principia"), was based on his own research and discoveries in mathematics and physics. The idea for the book came from his desire to develop a comprehensive system for explaining the workings of the natural world based on mathematical principles. He began working on the book in the 1660s, and it was first published in 1687.

Answers
Answer: The human circulatory system can be arranged from the highest to the lowest degree of internal organization as follows: Heart, Blood Vessels, Arteries, Veins, and Capillaries.
Explanation: The human circulatory system can be arranged from the highest to the lowest degree of internal organization as follows:
Heart: The heart is a vital organ responsible for pumping oxygenated blood to the body and deoxygenated blood to the lungs. It consists of chambers (atria and ventricles) and valves that regulate blood flow.
Blood Vessels: Blood vessels form a network of tubes that transport blood throughout the body. They can be classified into three types: arteries, veins, and capillaries.
Arteries: Arteries are thick-walled blood vessels that carry oxygenated blood away from the heart to various parts of the body.
Veins: Veins are blood vessels that transport deoxygenated blood from the body back to the heart. They have thinner walls compared to arteries and contain valves to prevent backflow.
Capillaries: Capillaries are tiny, thin-walled blood vessels that connect arteries and veins. They facilitate the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.

refers to the movement of a wave-like pattern from one location on the medium to
another. When you view a water wave moving along the surface of water, you are
observing wave motion. There is a very obvious movement of a collection of crests and
troughs along the water surface. In the Simple Wave Simulator, there is a collection of
crests and troughs moving through a rope this is wave motion. But there are also three
points on the rope that are colored red. When you observe the motion of these points.
you are observing particle motion - the motion of particles of the rope. Describe the
motion of these particles.
Answers
Answer:

Explanation:
One of the easier ways to define wave motion is the continuous movement of particles. When we have a rope for example and whip it, the first particle bumps into the second one then into the third and so on and so forth until the end of the rope. Particles can only move up and down or left and right and the vibration caused by each particle is what sets off the wave motion.
