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:
Wolf=1600kg*m/s
Elk= 8.89 m/s
Explanation:
p=mv
p=100*16
p=1600
1600=180*v
v=8.89 m/s
explain the forces of that affect the soccer balls path.
Answer:
yeah its correct
Explanation:
As the ball spins, friction between the ball and air causes the air to react to the direction of spin of the ball. ... Therefore, when a soccer player kicks the ball right of center the ball spins counter-clockwise and the Magnus force acts left, causing the ball to curve left.
a = 40
B= 75

A DAY IN THE LIFE OF METIS JOURNAL, I WROTE IT HOPE U LIKE IT ;))) XD
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.

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 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

Identify what happens to the kinetic energy (KE) and gravitational potential energy (PE) of a rock as it falls.
KE and PE both increase.
KE and PE both decrease.
KE increases and PE decreases.
KE decreases and PE increases.
Answer:
KE increases and PE decreases.
Explanation:
POTENTIAL ENERGY (PE):
The potential energy of the rock depends upon the height of the rock, as given by the following formula:
P.E = mgh
Therefore, the potential energy will be highest at the initial point due to the highest height attained by rock. As the rock falls, its height will decrease as a result its potential energy will also decrease.
KINETIC ENERGY (KE):
The kinetic energy of the rock depends upon the velocity of the rock, as given by the following formula:
[tex]K.E = \frac{1}{2}mv^2[/tex]
Therefore, the kinetic energy will be zero at the initial point due to the zero velocity of the rock. As the rock falls, its velocity will increase as a result its kinetic energy will also increase.
Hence, the correct option will be:
KE increases and PE decreases.
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.

How would the particles be arranged in an object that has a high density? What about in
an object that has a low density?
Answer:
Explanation:
The particles in solids are very close together. They are tightly packed, giving solids high densities.
The particles in gases are very far apart, so gases have a very low density.

10. What is the acceleration due to gravity at a location
where a 15.0-kilogram mass weighs 45.0 newtons?
1) 675 m/s2
2) 9.81 m/s2
3) 3.00 m/s2
4) 0.333 m/s2
Answer all of them an you will get the brain list
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
A hydraulic press consist of of two

smaller cylinder is pushed down
with a force of 100N through a
distance 0.2m. calculate
Links
(0)
The pressure transmitted
(ii)
The force exerted by the
piston in the larger cylinder.
Answer:
Explanation:
i )
area of small piston = 0.2 m²
Force = 100 N
pressure created on small piston
= 100 / .2 = 500 N/m²
According to Pascal's law , this pressure will be transmitted to larger cylinder .
area of larger cylinder = 5 m²
ii )
pressure = force / area
force in the large cylinder = pressure x area of large cylinder
= 500 x 5
= 2500 N .
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.
