Answer:
B. The ball makes a sound with each bounce, suggesting that some
kinetic energy transformed into sound.
Explanation:
The ball bounces, but each successive bounce is shorter than the one before it, and eventually, the ball comes to a stop as this statement explains, the ball makes a sound with each bounce, suggesting that some kinetic energy was transformed into sound, which is in option B.
What is the significance of the energy transformation?The energy transformation is a process in which one form of energy is converted into another form of energy, and it explains the law of conservation of energy as the energy only changes its form but is never destroyed, such as in plants where the solar energy is converted into the chemical energy that is the glucose.
Hence, the ball bounces, but each successive bounce is shorter than the one before it, and eventually, the ball comes to a stop as this statement explains, the ball makes a sound with each bounce, suggesting that some kinetic energy was transformed into sound, which is in option B.

A person runs 2 laps around a 400 meter track and stops where they initially
began running. It took this person 3 minutes and 18 seconds to complete this
run. What is this persons average velocity?
A:4.04 m/s
B:2.02 m/s
c:0 m/s
The runner's total distance covered was 800 meters. Her displacement (straight-line distance between start-point and end-point) was zero.
Her average speed = (distance)/(time) = 4.04 m/s
Her average velocity = (displacement) / (time) = zero (choice - c)

A tea kettle is used to boil liquid water. When the water is boiling, a whistling sound comes from the kettle. Which provides the best explanation for the sound?
A. The liquid particles are sliding past each other slowly as the temperature increases
B. The gas particles are being pushed below the water at the bottom of the kettle.
C. The gas particles spreading out in all directions are being pushed quickly through a small opening.
D. The liquid particles are moving very quickly to the center of the kettle and pushing any gas particles out of the way.
Answer:
C would be the correct answer
Answer:
It has to have a whistle device on the spout. When boiling occurs, water vapour displaces air above the water which has to escape through the whistle hence activating the required vibrations. Thereafter, the continuing supply of steam does the same job until the cook involves turns off the heat. The whistle is not made to exacting scientific standards and there is no doubt a range of pressures above which it will work it. It would be interesting to know how you observed the water boiling without using a transparent kettle.

Ralston had lots of spicy and oily food which triggered heartburn. The doctor prescribed
him Milk of Magnesia.
a. Why did the doctor prescribe milk of magnesia?
b. What is the chemical name of milk of magnesia?
Answer:
A.) The doctor decided to prescribe milk of magnesia because of the mineral Magnesium. Magnesium helps to reduce stomach acid and increases the water in the intestines which helps induce motility in the intestines. Heartburn is caused by stomach acids traveling up into your esophagus which causes that feeling of your heart burning. Milk of magnesia will help soothe this.
B.) The chemical name of milk of magnesia is magnesium hydroxide.
Explanation:
The chemical name of the milk of magnesia is magnesium hydroxide.
An antacid is any substance that is taken to decrease or neutralize the acidity of the gastro intestinal tract. We must note that the gastrointestinal tract is natural acidic.
However, hyperacidity of the gastrointestinal tract could lead to heartburn. This acidity is neutralized using an antacid such as milk of magnesia. The chemical name of the milk of magnesia is magnesium hydroxide.

Answer:
4. Force = 178.6 Newton.
5. Acceleration = 2.28 m/s².
6. Force = 178.6 Newton.
Explanation:
4. Given the following data;
Acceleration = 3.8 m/s²
Mass = 47kg
Force = mass * acceleration
Force = 47 * 3.8
Force = 178.6 Newton.
5. Given the following data;
Force = 785N
Mass = 345kg
Acceleration = force/mass
Acceleration = 785/345
Acceleration = 2.28 m/s²
6. Given the following data;
Acceleration = 6m/s²
Force = 32N
Mass =force/acceleration
Mass = 32/6
Mass = 5.33 kilograms

Calcular la aceleración que produce una fuerza de 40 N sobre un cuerpo con 88 Kg de masa. Expresar el resultado en m⁄s^2 *
Answer:
a = 0.45 m/s²
Explanation:
The given question is ''Calculate the acceleration that produces a force of 40 N on a body with 88 kg of mass".
Given that,
Force, F = 40 N
Mass of the body, m = 88 kg
The net force acting on the body is given by :
F = ma
Where
a is the acceleration of the body
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{40\ N}{88\ kg}\\\\a=0.45\ m/s^2[/tex]
So, the required acceleration is 0.45 m/s².

A woman runs 4.5 miles south and 3,7 miles east. What is the angle of the displacement of the resultant?
Answer:
51°
Explanation:
Please see attached photo for explanation.
In the diagram, R is the resultant and θ is the angle of the displacement of the resultant.
The value of θ can be obtained as follow:
Angle θ =?
Opposite = 4.5 miles
Adjacent = 3.7 miles
Using Tan ratio:
Tan θ = Opposite / Adjacent
Tan θ = 4.5 / 3.7
Tan θ = 1.2162
Take the inverse of Tan
θ = Tan¯¹ 1.2162
θ ≈ 51°
Thus, the angle of the displacement of the resultant is 51°
"Influence" between bodies is reduced as the bodies are: brought closer moved farther apart increased in charge held stationary
Answer:
moved farther apart
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
"Influence" between bodies is reduced as the bodies are moved farther apart based on Newton's law of universal gravitation.
Newton's law of universal gravitation states that the force of attraction (gravity) acting between the Earth and all physical objects is directly proportional to the Earth's mass, directly proportional to the physical object's mass and inversely proportional to the square of the distance separating the Earth's center and that physical object.

How does inertia relate to forces
Answer:
Even in space, objects have mass. And if they have mass, they have inertia. That is, an object in space resists changes in its state of motion. A force must be applied to set a stationary object in motion.
