Rarefraction.
Crest- tallest spot on transverse wave.
Trough- shortest point on transverse wave.
Compression - spot on a compressional wave where the waves are closer together.
Rarefraction - spot on a compressional wave where the waves are farther apart.
answer:
yes
explanation:
At a separation of the surface of Earth (r=6400km) gravity wants pull the test mass closer and closer. ... So the work done by gravity is NEGATIVE. The gravitational potential energy is negative because us trying to do the opposite of what gravity wants needs positive energy.
Answer:
Option D. Weight varies with location, but mass does not.
Explanation:
To know which option is correct, it is important that we have a background knowledge of mass and weight.
A brief summary of the difference between mass and weight is given below:
1. Mass is the quantity of matter present in an object while weight is the gravitational pull on an object.
2. The SI unit of mass is kilogram Kg) while that of weight is Newton (N)
3. Mass is constant while weight varies by location.
4. Mass can measured using a chemical balance or beam balance while weight can be measured using a lever or spring balance.
With the above information, we can see that mass of an object is always but the weight varies by location.
