Mass, velocity, and radius that the answer
Answer:
0.5 m/s
Explanation:
Velocity = displacement/time taken
going 15 meters east and then 20 meters west gives a displacement of 5 meters.
Velocity v = 5/10
= 0.5 m/s
Answer:
4°C
Explanation:
Water is densest at 4°C. Since dense water sinks, the bottom of the lake will be 4°C.
Answer : Option D) A dropped wallet is kicked around the floor of a busy train station.
Explanation : The description that best suits the model for the energy transfer that occurs in the radiative zone is -
<h3>A dropped wallet is kicked around the floor of a busy train station.</h3>
As in the radiation zone, which is also called as radiative zone or radiative region in the layer of a star's interior where energy is primarily transported toward the exterior by means of radiative diffusion and thermal conduction. This can be correlated with the example of a dropped wallet in a busy train station as the wallet would be kicked by many people who are in a hurry to travel, this represents the radiative diffusion. So, every time the wallet is being kicked by someone the energy is getting transformed.
Answer:
It is less than 25m/s as the correct average is 24m/s.
Explanation:
This is becuase you need to take the average of the two speeds (18m/s and 30m/s) 18 + 30 divided by 2 is 24m/s.
