How does the velocity of a moving object depend on the choice of frame of reference?

Answers

Imagine you threw and caught a ball while you were on a train moving at a constant velocity past a station. To you, the ball appears to simply travel vertically up and then down under the influence of gravity. However, to an observer stood on the station platform the ball would appear to travel in a parabola, with a constant horizontal component of velocity equal to the velocity of the train. This is illustrated in Figure 1 below.

(Path of the ball as seen by an observer on the train and an observer at the station.)

The different observations occur because the two observers are in different frames of reference. A frame of reference is a set of coordinates that can be used to determine positions and velocities of objects in that frame; different frames of reference move relative to one another.

The laws of physics are the same in all inertial frames (this is known as Galilean invariance). Put in another way, there is no experiment that you could do to determine which reference frame you are in (Einstein used this hypothesis to devise the theory of Special Relativity). This means that we can address problems in any reference frame to give an equivalent solution.

1. if i start with 48 ml of water in a graduated cylinder, after submerging an object the water level rises to 63 ml, what is the volume of the object.
2. if i start with 36 ml of water in a graduated cylinder, after submerging an object the water level rises to 43 ml, what is the volume of the object

Answers

1.
63-48
= 15 ml

Since the water rises 15 ml in the graduated cylinder, its volume is 15 ml^3

2. 43 -36

Explain the role of gravity and inertia on the motion of objects in the solar system.

Answers

Like all objects with mass, planets have a tendency to resist changes to their direction and speed of movement. This tendency to resist change is called inertia, and its interaction with the gravitational attraction of the sun is what keeps the planets of the solar system, including Earth, in stable orbits.

Why is cellular respiration essential for homeostasis? (4 points)

To create energy that the cell can use

To make air in the body

To remove oxygen from tissues

To make new types of cells

Answers

1Cellular respiration supports homeostasis to maintain the stability of body. ATP is produced during cellular respiration that provides energy to perform several body functions such as muscle contraction and nerve conduction which are responsible for the maintenance of homeostasis
2. The only form of energy a cell can use is a molecule called adenosine triphosphate (ATP). Chemical energy is stored in the bonds that hold the molecule together. ADP can be recycled into ATP when more energy becomes available
3. The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
4. The regulation of tissue oxygenation is based at the start from the ability of the respiratory system to fully oxygenate the arterial blood which the heart then delivers to the peripheral tissues. The need for different levels of respiration varies with the physiologic state of the organism (e.g., sleep, excitement, exercise). The respiratory system must try to maintain constant levels of O2, CO2 and H+ in the arterial blood which then ensures relatively constant levels of these important substances in the interstitial fluid. For O2, one needs an adequate supply to meet cellular metabolic requirements. For CO2 and H+, one needs to maintain the acid–base status of the body's cells
5. New cells are created from a process called cell division. The new cells are produced when a cell, called the mother cell, divides into new cells called daughter cells. When two daughter cells have the same number of chromosomes as the original cell, the process is called mitosis
To create energy that the cell can use hope this helped x

Answers

Answer:

Actually, Sherman, there are more black moths than white ones because of natural selection. The black moths blend into the environment, while the white moths do not. This means that the predators of the moths will find and eat more white moths than black moths. Then, this leads to more black moths and fewer white moths, since black moths have a better chance of surviving and reproducing.

A skateboarder pushes the ground with one foot, and moves forward.

Which statement BEST explains his motion?
The mass of the skateboard decreased causing acceleration to move him forward.
The unbalanced force exerted by the skateboarder’s foot caused him to move forward.
The mass of the student and skateboard increased causing acceleration to move him forward.
The balanced forces on the skateboard allowed it to change his motion and move him forward.

Answers

Answer:

C or D i would think would be the answer

The unbalanced force exerted by the skateboarder’s foot caused him to move forward.

When a skateboarder pushes the ground with one foot, the board moves forward. This is because of the unbalanced force exerted by the skateboarder’s foot caused him to move forward.

This is an application of Newton's first law, which states that, an object in motion or uniform motion will continue its state unless it is acted upon by an external unbalanced force.

Here, the unbalanced force exerted by the foot on the ground causes the board which was at rest to move forward.
