Answer:
I would use the model of Ammonia because it helps you visualize the structure of NH3 better than the description. It would be easier to understand the structure of it if you can see it, rather than reading its description.

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?
Answers
Answer:
Wolf=1600kg*m/s

Explanation:
p=mv
p=100*16
p=1600
1600=180*v
v=8.89 m/s
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
Answers
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

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

Earl travels 50m east in 10 minutes and later 100m north in 15 minutes. What is her total displacement?all travels 50 m East in 10-minutes and later 100m not in 15-minutes determine the total displacement recovers
Answers
Answer:
111.8 m
Explanation:
Displacement is the change in position of an object. The SI unit of displacement is the meters. The displacement of an object can be calculated by determining the shortest distance from the starting point to the end point.
Since earl travels 50 m east and then 100 m north, let x represent the displacement. Therefore x is the shortest distance from starting to end. Earl movement forms a right angled triangle with x as the hypotenuse. Hence:
x² = 50² + 100²
x² = 12500
x = 111.8 m

We, who live in the west, were Nomadic. So we always moved from place to place to hunt buffalo and other fur-bearing animals. And now again we have to shift everything we collected , like, all the essential needs we collected. It’s really hard to shift stuff, But when you move to a new place you get to see new beautiful places. They are just so satisfying to see! It’s like all my work(like the shifting work) is paid off. I love it! We always meet the Hudson’s bay company employees, and give them furs which we took from the bissons and other furry animals we hunted. And in exchange they give us their (Hudson’s Bay company) goods. Which is good! Because then we or I won't be able to enjoy that delicious pemmican!
The one reason that makes me proud of my parents is that because of them I am like a translator for both sides in the fur trade! Anyways coming back to the present. As I said before, we were moving today to another place, But on the way some people along with my father will ride the famous York boats carrying supplies to fur posts. I begged my father to take me with him! And as usual he gave me some silly reason for me to stay. And now since I don’t have anything to do I will-..Nevermind, My mom’s calling me. Okay after helping my mom keep the fur posts into the York boats me , my mom, and the others are just relaxing and enjoying nature just to take a break. Since, I am so obsessed with my Journal notebook today I’m just going to sit here and right what comes to my mind. I’m not like the others who always seem to be talking with someone. I like my own space!
I kind of miss my dad already, but he and his fellow members need to travel the waterways from the red river further west and north to hudson bay. These red river carts also travel the trek back and forth over land to St. Paul, Minnesota and to posts in saskatchewan. Speaking about the red river, the only large settlement in the region is the red colony. About 12000 people lived in this colony around Fort Garry. Some were the original Selkirk settlers or their descendents. They had come from Scotland with lord Selkirk when he established the colony in 1811. Many of these original settlers were poor farmers who had been displaced from their lands in scotland. They had endured many hardships in the early years of settlement, including foods, hunger, and sickness. I love studying about other colonies, cultures , history etc.

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?
Answers
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.

"Influence" between bodies is reduced as the bodies are: brought closer moved farther apart increased in charge held stationary
Answers
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.
