why is water further away from the shore colder the further you go?
Answer:
★ For example, cold water has a higher density than warmer water. In Addition, water gets colder with depth because of the coldness, of the salty ocean water which sinks to the bottom of the ocean basins below the less dense water near the surface

A person’s blood type depends on the type of protein marker, called an , found on the cell membranes of the red blood cells.
A person’s blood type depends on the type of protein marker, called an Antigen, found on the cell membranes of the red blood cell.
What is antigen?A molecule known as an antigen is one that triggers the formation of an antibody and the immune system's response.
Large protein molecules known as antigens are found on the surface of pathogens like bacteria, fungi, viruses, and other foreign substances. When these dangerous substances enter the body, the body's immune system reacts by producing antibodies.
The ABO system distinguishes 4 major blood types:
Blood group O - has no antigens, but both anti-A and anti-B antibodies in the plasma. Blood group AB - has both A and B antigens, but no antibodies.Blood group A - has A antigens on the red blood cells with anti-B antibodies in the plasma. Blood group B - has B antigens with anti-A antibodies in the plasma.Learn more about antigen here:

Hi, I have a question if I calculate the average force that must be exerted on a 0.145 kg baseball for me to give it an acceleration of 130 m/s2. How would I get I get the acceleration would I divide 130 by 0.145 kg to get the acceleration?
Think about the types of forces holding the atoms together in different chemicals. Are there any patterns that can be drawn from the data? Explain.
Hello. You did not enter the data to which this question refers, which makes it impossible for it to have an exact answer. However, I will try to help you in the best possible way.
The forces that hold the elements together are called intermolecular forces. They are formed by covalent bonds between the molecules and can be called: dipole-induced (occurs between nonpolar molecules that have a negative pole and a positive pole) and dipole-dipole (occurs between polar moileculas, except when hydrogen is present).
Mr. White drops a bowling ball and a feather from the top of the Washington Monument.
a) Which will hit the ground first? Why?
b) If Mr. White were to repeat this experiment inside a vacuum chamber, which would hit the ground first? Why?
If you can provide some explanation I would greatly appreciate it! :)
Answer:
A) The bowling ball will hit the ground first. It is heavier, which has greater density, allowing it to reach the ground first.
B) Feather. If you want to be able to blow a bowling ball in a vaccum cleaner, it's almost impossible since it's very heavy. If it's a feather, it would be easier as it's light and the air inside it is able to force it down.
Note: I haven't learnt physics at all yet, this is just an attempt. I'm in 7th grade currently and I will probably be taking physics sometime in 9th grade.
As altitude increases in the troposphere and stratosphere, the air temperature does what?
A. decreases in the troposphere and increases in the stratosphere.
B. Decreases in both places.
C. Increases in the troposphere and decreases in the stratosphere.
D. Increases in both places
Answer:
1
Explanation:
The correct answer is decreases in the troposphere and increases in the stratosphere.
How does altitude affect the troposphere?For this reason, the density of gases decreases as the distance from Earth's surface increases. Put another way, air pressure (i.e., density) decreases as altitude increases.
How can altitude affect the temperature of a place?The temperature of a place decreases with increasing altitude from the earth's surface.

Example of kinetic to potential ? And how the energy is changing forms???? Please help
Answer:
A ball when from moving to stoping
Explanation:
Kinetic = energy of motion
Potential = energy stored
When you roll a ball on the ground, it gains kinetic energy, but then the ball starts to slow down until it stops and it remains at rest which means it's at potential energy. It went from moving (kinetic) to stoping (potential)
Hope this helped!

How might electric fields be involved in a levitation device?
Answer:
When a magnet is moving relative to a conductor in close proximity, a current is induced within the conductor. This induced current will cause an opposing magnetic field. This opposing magnetic field can be used to levitate a magnet.

HELP + extra pts // Two 10-m high diving platforms are at opposing ends of a 30-m pool. How fast must two clowns run straight off their boards if they want to collide at the middle of the pool and the surface of the water?
Explanation:
The clowns need to leave the diving boards with enough horizontal velocity such that each travels 15 m (half the width of the pool) in the same time that they fall (vertically) the 10-m from the top of the diving board.
We'll assume no force acts on the clowns horizontally to slow them down while they are in flight. And we'll assume that only gravity acts on the clowns vertically.
We can treat the horizontal and vertical components separately. This will help simplify the problem.
Let's start with the vertical displacement. Let's say the clown is dropped from a height of 10-m. How long would it take them to fall that distance?
Using our equations of motion (with constant, linear acceleration), we can solve for this time. [tex]d = vt + \frac{1}{2} at^2[/tex]
Where d is the distance travelled, v is the initial velocity, a is acceleration, and t is time.
If the clown is dropped, they have an initial velocity of 0 (zero). We assumed only gravity acts on the clown, so acceleration equals the gravitational acceleration on earth. [tex]a = 9.8m/s^2[/tex]
The distance the clown travels is 10-m from the diving board to the surface of the water.
Let's solve. [tex]10 = 0*t + \frac{1}{2} (9.8) t^2 \rightarrow 20/9.8 = t^2 \rightarrow t = \sqrt{20/9.8}[/tex]
Now that we know time, we can calculate how fast the clown needs to be running when they leap from the diving board to cover a distance of 15-m (Remember, half the width of the pool.)
Using our equations of motion, we know that [tex]d = vt + 0.5at^2[/tex]
We assumed no forces act horizontally on the clown, therefore a = 0. We just need to solve for v. Substituting in the time we just solved for, we get something like this. [tex]15 = v \sqrt{20/9.8}[/tex]
I'll leave it to you to solve this equation.

Answer:
1. the rocks at the bottom of the aquarium
2.the fish and maybe the plants (if you use live plants)
3. fish interact with there no living things like how one would hide in the grass or something like that.
4. decorations (like a cave or fake house, tho the aquarium its self is a home)
5.they would die, and rot.
Explanation:
rocks are nonliving
fish are living things and so are plants
fish can hide in the plants
the fish can "live" in the decorations, but the aquarium itself is its home.
if something reaches the end of its life span it dies.
A student wants to test the force of magnetism by placing objects on top of a piece of cardboard and then moving them with a magnet placed under the cardboard. Which items will help the student with this investigation?
Answer:
Any material that has ferromagnetic property
Explanation:
Materials such as iron, nickel or cobalt are ferromagnetic element as they behave as small magnets in the presence of moving electric charge or static magnetic field.
When an external magnetic field is applied these ferromagnetic material align in a way that they contribute to produce a stronger magnetic field in the material and remain aligned even after removal of the external magnetic field.

4. If the velocity of the particles is high, they will collide with each other with less force.
a. TRUE
b. FALSE
Answer:
7657
Explanation:
b. FALSE
If the velocity of particle is high then they will collide with each other with a greater force because their momentum will be high
What is force?force is a push or pull on a body .
What is momentum?Momentum is the product of mass and velocity,
More the velocity, higher will be the momentum.
since force is directly proportional to rate of change of momentum
F = Δp/Δt
so on when bodies having higher velocities collide their rate of change of momentum is higher hence more will be the force
