<h3><u>Answer;</u></h3>
Are moving up and down.
As a transverse wave travels through a rope from left to right, the parts of the rope <u>are moving up and down</u>.
<h3><u>Explanation;</u></h3>
- Transverse waves occur when a disturbance causes oscillations perpendicular to the propagation, that is the direction of energy transfer.
- <em><u>Particles of the medium move perpendicular to the direction the transverse wave itself is moving. For example, if the wave is moving to the right, the particles of the medium are moving up and down.</u></em>
- <em><u>Therefore, as a transverse wave travels through a rope from left to right, the parts of the rope are moving up and down.</u></em>

a) Velocity is a vector quantity
e) Velocity is a speed with direction
=================================================
Explanation:
If we know the velocity of an object, then we know how fast it's going (speed) and where it's going (direction). It is a vector because the direction of the vector determines the direction, and the length of the vector (aka magnitude) determines the speed. So in a sense we've built in two facts of data into one visual.
An example of velocity: 10 miles per hour north. Here we have the speed of 10 mph and the direction north.
-------------------
Extra info:
- Choice B contradicts choice A, so we can cross choice B off the list.
- Choice C is false because speed is a scalar, or single quantity, and not a vector. As mentioned earlier, speed is a part of velocity, but they aren't the same exact thing.
- Choice D is false because the velocity does not account for net force. We don't have any force information built into the velocity.
Answer:
A. Repeating an experiment to verify results
Explanation:
A scientific theory may be defined as the theory of science that is a thought out explanation of the observations done in the nature or that happens in the natural world. They are constructed using several scientific methods by observing many facts and hypothesis.
According to the question, repeating of an experiment a number of times and verifying its result may help in improving a scientific theory as if we get the similar result for each experiments, then it confirms the basis of the hypothesis or the facts that are observe in the nature and conclude a scientific theory.
Answer:
Explanation:
Given:
- mass of the object,
- weight of the object on planet x,
- radius of the planet,
- radial distance between the planet and the object,
