Spiral galaxies are still undergoing star formation
What are the answers?
in order to get help i would need the answers :)
In this item, we are asked to determine the correct definition for the terms. It is unfortunate that they meanings to which we could match them are not given. With that, the answers written here are the well-researched ones.
Solution --> This type of erosion happens when the components found in the rocks (i.e. limestone) are dissolved through the acid components of acid rain.
Abrasion --> This is a process by which the rocks that are eroded to the riverbanks wear down other components of the bed.
Saltation --> This process involves the movement of the particles through a series of bounces that are short and are along the surface of the ground. This results to dislodging the other particles.
Answer:
6.52 m/s
1.72 m/s
5.38 m/s
Explanation:
this question requires us to find the average velocity.
1. velocity in straight down direction:
velocity = distance/time
= 15.0/2.30
= 6.52 m/s
2. velocity in straight backward direction:
velocity = distance/time
= 3.00 /1.74
= 1.72m/s
3. velocity in straight forward direction
velocity = distance/time
= 28.0/5.20
= 5.38 m/s
these are the his velocities for each if the intervals.
thank you!
