Answer:
B.The slinky descriptions of motion are switched.
Explanation:
First of all, let's define the two types of wave:
- Transverse wave: in a transverse wave, the oscillation of the wave occurs in a direction perpendicular to the direction of propagation of the wave. An example of transverse wave are electromagnetic waves.
- Longitudinal wave: in a longitudinal wave, the oscillation of the wave occurs in a direction parallel to the direction of propagation of the wave. An example of longitudinal wave are sound waves.
According to these definitions, we notice that the following descriptions of motion must be switched:
- "Like moving a spring up and down" --> this better describes a transverse wave, because the motion up/down is perpendicular to the direction of the spring
- "Like moving a spring back and forth" --> this better describes a longitudinal wave, because the back/forth motion is parallel to the direction of the spring
Answer: C. Magnitude increases by 2
Explanation:
Answer:
It simply means that, the pencil is long enough to attain a length of six (6) centimeters when measured with a measuring tool such as a ruler, tape, etc.
Explanation:
A scientific method can be defined as a research method that typically involves the use of experimental and mathematical techniques which comprises of a series of steps such as systematic observation, measurement, and analysis to formulate, test and modify a hypothesis.
Measurements refers to a process which typically involves identifying and determining the dimensions of a physical object. The dimensions include important parameters such as width, height, length, area, volume, circumference etc.
Hence, a pencil whose length is measured as 6 centimeters has a physical dimension that covers a distance of six (6) centimeters in terms of size.
In conclusion, the pencil would cover a length of six (6) centimeters when measured vertically and a corresponding height of six (6) centimeters when measured horizontally.
Answer:
We will be effected not only with health, but also with our ability to carry out our genes to the next generation.
Explanation:
Our health is important, as we all know, so anything that happens to the digestive system will have a serious problem to our longevity, our reproductive system is also important to carry out our genes, and give birth to a new generation, it wouldn't effect us if only 1 person couldnt reproduce, but if everyone had a problem in their reproductive system, it would mean the extinction of all humanity.
