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.

A parked car begins to roll down a hill, what can you conclude from that observation?
A force was required to start the car rolling.
The rolling friction is equal to the car’s weight.
The rolling friction is greater than the force of the car’s weight against the hill.
The car will stop when a force equal to the weight of the car is applied against the car.

What are biomes?Biomes can be defined as regions specified by particular biological and geographical communities that evolved because of the shared regional climate of that region.
In the natural world, symbiotic partnerships can take one of three main forms: parasitism, commensalism, or mutualism. Mutual benefit: both parties win.
There are certain populations that work together. The right response is option C since this is a situation in which individuals of the same species collaborate in order to survive.

50 points to the first person!!!!!
Answers
Answer:
Your stomach acid helps you break down and digest your food. Sometimes, a higher than normal amount of stomach acid can be produced. This can lead to symptoms like abdominal pain, nausea, bloating, and heartburn.
Explanation:
brainliest plz
Answer:Stomach acid, or gastric acid, is a watery, colorless fluid that’s produced by your stomach’s lining.It’s highly acidic and helps break down food for easier digestion. This helps your body absorb nutrients more easily as food moves through your digestive tract.In order to break down everything from meat to tough, fibrous plants, stomach acid has to be highly acidic.Your body is designed to handle normal levels of stomach acid so it doesn’t cause you any illness or health complications.
Explanation:Stomach acid encounters a lot of things on behalf of your body. It breaks down the foods you eat into easier-to-digest particles. It also acts as the first line of defense against pathogens and microbes that could make you sick.

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.

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.
