When Tyler drives 50 km north and then drives back 30 km south, we have:
1. The distance that he covers is 80 km.
2. Tylor's displacement is 20 km.
1. The distance is a scalar that is given by the sum of the kilometers traveled by Tyler as follows:
Hence, the distance traveled by Tyler was 80 km.
2. The displacement is a vector that depends on the direction of travel. Takin the north direction as positive we have:
Therefore, Tyler's displacement is 20 km.

I hope it helps you!
Answer:
80 km is distance and 30km north is displacement
Explanation:
distance= 50+30=80km
displacement= 50-20=30
his displacement is 30km north
B. increasing the string's thickness.
C. loosening the string.
D. lengthening the string.
In a stringed musical instrument, the sound frequency of a particular string can be increased by tightening the string (option A).
The frequency of a vibrating string determines the pitch of the sound it produces. Higher frequencies result in higher-pitched sounds, while lower frequencies produce lower-pitched sounds.
By tightening the string, the tension in the string increases. This increased tension leads to an increase in the frequency of vibration of the string when plucked, bowed, or struck. As a result, the pitch of the sound produced by the string becomes higher. Option A is therefore correct.

Other words for saying that a wave is "transmitted" through a medium are transmission, propagation, spread.
"Wave is a phenomenon or disturbance in which energy is transferred from one point to another without any direct contact between them." For example: Heat, light and sound is considered as a wave.

Answer:
No
Explanation:
It is an example of experimental group. Experimental group is defined as the group in an experiment under which each variable is tested, however, one variable is tested at a time.
On the other hand, control group is defined as the group which does not receive treatment by the researchers.
The only difference between the both group is that, under experimental group independent variable is changed but under control group it is held constant.
