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.
A ball is thrown 6m above the ground. Its total energy at that point is 12 J. What is the total energy of the ball at a halfway point of motion
Answer:
6J
Explanation:6J
Using the potential Energy formula;
Potential Energy = mass * acceleration due to gravity * height
If a ball is thrown 6m above the ground. Its total energy at that point is 12 J
Get the mass of the ball
12 = m * 9.8 * 6
m = 12/58.8
m = 0.204kg
The height of the ball halfway = 6/2 = 3m
Potential energy half way = mgh
Potential energy half way = 0.204 * 9.8 * 3
Potential energy half way = 6J

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°

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.

If the amount of force from the group on the left was 235 N, what is the amount of force from the group on the right
Answer:
(F = ma ) Newton's second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object's mass multiplied by its acceleration.

Show your work: A wolf chasing an elk. The wolf has a mass of 100 kg and is running with a velocity of 16 m/s
to the right. What is the wolf's momentum?
The elk has a mass of 180 kg. What does the elk's speed have to be for it to have the same momentum as the
wolf?
Answer:
Explanation:
wolfs momentum is p=mv
so its 100 x 16 = 1600kg m/s
the elks velocity is 1600 = 180 x V
1600/180 = 8.88 m/s
A girl travels 50 m East in 10-minutes and later 100m north in 15 minutes. what is her total displacement?

If you wish, each student can talk about some other aspect of the pandemic that seems important and interesting then you have to give them the assignment of presentation and give reward on them. The students will definitely make the presentation on other aspects of the pandemic and when they present it in the class it enhance the knowledge of other students as well.
"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.

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.
