what????????
Explanation:
Why does your boat float but not your ring?
The air that is inside a ship is much less dense than water. That's what keeps it floating! ... The closer the total density of the ship is to the density of the same volume of water, the greater the amount of the ship that will be in the water.
a = 40
B= 75

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.

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.

Which change happens in an endothermic chemical process??
Answer:
The thermal energy is absorbed
Explanation:
In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction.
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 hydraulic press consist of of two
cylinders of cross sectional areas
0.2m2 and 5m². The piston in the
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 .
- What is the net force of 150 N → and ← 275 N?
Answer:
Net force = 125N
Explanation:
Let the two forces be A and B respectively.
Given the following data;
Forward force, A = 150N
Backward force, B = 275N
To find the net force;
Since the two forces are acting in opposite directions, we would subtract them to get the net force.
Net force = B - A
Net force = 275 - 150
Net force = 125N

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.

Can someone explain what is referred by the cross sectional area of a solenoid? Is this the same for an air solenoid vs a solenoid with a solid core vs a solenoid with a hollow core?
Answer:
the cross section refers to the way in which it is wound, in general to the circle
circle does not depend on what it has inside
Explanation:
A solenoid is a wire wound in general in a circular shape, even when it is not forced, the cross section refers to the way in which it is wound, in general to the circle and is joined to determine the area
A = π r²
This circle does not depend on what it has inside, that is, it is the same section in the air, in a liquid or with a solid inside,

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.
