Answer:

The saddle joint allows movement in different directions but only a small amount of rotation. The thumb is the only organ that has a saddle joint.

It should be noted that the bones that are in the saddle joint ensure the back and forth movement of the thumbs.

The pivot joint is the joint that's responsible for ensuring that one bone rotates around another bone. Ball and socket joint can be found in the shoulder and the hip and it allows for greater freedom of movement.

When compared to other movable joints, the saddle joint is prone to dislocation because it's free-moving and rotates on its own axis alone.

In conclusion, if the thumb contained a pivot joint or a ball and socket joint, it'll be able to move more freely.

Astronauts float around in space because there is no gravity in space. Everyone knows that the farther you get from Earth, the less the gravitational force is. Well, astronauts are so far from the Earth that gravity is so small. This is why NASA calls it microgravity.

Explanation:

Answer:

The gas, which is usually a hydrocarbon fuel, provides the energy. So when the fuel burns with oxygen in the air, it creates heat energy.

Explanation:

Therefore, chemical energy in carbon is released during the combustion process. Carbon dioxide is created, because the carbon-oxygen chemical bonds in the carbon dioxide form which releases heat.

Answer:

It should be less energy

Explanation:

The further away from the nucleus, the more it holds, correct? So those closer to the nucleus hold less electrons. So therefore, the ones that are closer must have more energy than the outer electrons.

The physical evidence are the silent witnesses against the perpetrators of a crime

The correct option of what the field inspector packages after the crime scene has been photographed is the option;

Reason:

Physical evidence are evidence that originate from inanimate objects or origin that is nonliving, and includes every material or object that serve as an indicator that someone has committed a crime, or that can link a perpetrator to crime

Examples include; Documents, hair, skin, fingerprints, weapons, soil, or fibers

The field inspector, collects the evidence that shows that a crime has been committed which are the physical evidence, after the crime scene has been photographed

Answer:

(C)

Explanation:

its C ok

The transition that will lead to the emission of light with longer wavelengths is n = 3 to n = 2. The correct option is c.

The largest energy change, and hence the shortest wavelength, x nm, would occur during the transition from the highest to the lowest energy levels. When an electron moves from the n = 5 to the n = 1 level, an atom emits yellow light.

The Bohr model of the atom is named for Niels Bohr, who created a model of the electron in which electrons were arranged into energy levels using observations of atomic spectra.

Because electrons can only exist in the energy levels and not in the intermediate states, they must absorb or emit a certain amount of energy to change energy levels.

Therefore, the correct option is c. n = 3 to n = 2.

In order to increase the momentum of the ball, you have to increase its speed.

The first and third choices on the list ('A' and 'C') will do that.

The factors that will increase momentum of a rolling ball are:

A. Moving from a flat surface to moving downhill.

C. A moving object traveling in the same direction as the ball colliding with it.

The gravitational power of the Earth ready makes the ball speed up, and in this manner pick up speed.

If you increase either mass or velocity, the momentum of the object increases proportionally.

Thus, the factors that increase the momentum of a rolling ball are

A. Moving from a flat surface to moving downhill.

C. A moving object traveling in the same direction as the ball colliding with it.

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.

Explanation:

have a beautiful day ahead

Magnetic fields can be mapped out using small plotting compasses : place the plotting compass near the magnet on a piece of paper. move the plotting compass to many different positions in the magnetic field, marking the needle direction each time. join the points to show the field lines.

Answer:

Gravity

EXPLANATION:

In the vertical or y direction, however, the projectile experiences the effect of gravity. As a result, the y component of the velocity  is not constant, but changes. The y component of the acceleration ay is the downward acceleration due to gravity.

Answer:

1.Cells are the basic structural unit of all living organisms.

Answer:

It has three main parts:

1. All living things are made up of cells.

2. Cells are the basic building blocks of life.

3. All cells come from preexisting cells created through the process of cell division.

Explanation:

As science evolved, three more components were added to the theory. Some biology classes don’t require you to know these parts of the cell theory because they weren’t part of the original definition, but it’s still useful to be aware of them:

4. Energy flow occurs within cells.

5. Hereditary information is passed from cell to cell.

6. All cells have the same basic chemical composition.

So what does the cell theory actually mean? Let’s break it down. The first part of the cell theory states that all living things are made up of cells. Anything that’s alive, from bacteria to plants to humans, is composed of cells. And what are cells? The literal definition is a cell is a group of organelles surrounded by a thin membrane.

The cell theory definition states that cells are the building blocks of life. Cells both make up all living things and run the processes needed for life. Your hair, skin, organs, etc. are all made up of cells. In fact, each person is estimated to be made up of nearly 40 trillion cells! Each part of a cell has a different function, and your cells are responsible for taking in nutrients, turning nutrients into energy, removing waste, and more. Basically, everything your body does, it does because cells are directing the actionThe third part of the cell theory definition states that all cells come from preexisting cells. This means that cells don’t just appear out of thin air (known as “spontaneous generation”). New cells are always made from current cells. This means that all current life on the planet is descended from the very first cells, which first made an appearance on Earth roughly 3.5 billion years ago. Cells have been replicating themselves continuously ever since.

And what does the newer part of the cell theory state? Part four refers to the fact that, in all living cells, energy is continuously transformed from one type to another. Examples of these processes include photosynthesis (where plant cells convert light energy into chemical energy) and cellular respiration (where both plant and animal cells convert glucose into energy). Part five refers to DNA and the fact it is passed from parent cell to child cell. Finally, part six of the cell theory tells us that all cells are made up of the same chemicals: water, inorganic ions, and organic molecules.!

The speed of the ball when it returns to the same horizontal level is 8 m/s.

The given parameters;

During the motion of a projectile, the speed of the projectile reduces as the projectile moves upwards and eventually becomes zero at the maximum height.

As the projectile moves downwards, the speed of the projectile starts to increase and it will become maximum (equal to the initial speed) before the projectile hits the ground.

Thus, we can conclude that the speed of the ball when it returns to the same horizontal level is 8 m/s.
