Odina walked down the hall at school from the cafeteria to
the band room, a distance of 100.0 m. a class of physics
students recorded and graphed her position every 2.0 s,
noting that she moved 2.6 m every 2.0 s. when was odina
in the following positions?
a. 25.0 m from the cafeteria
b. 25.0 m from the band room
c. create a graph showing odina’s motion.

Explanation:

As we know that when graph is plotted with the position and time then it shows that it will move with uniform speed

So here it is moving 2.6 m in 2 s

so speed is given as

Part a)

when she reach 25 m from cafeteria

time taken by her

Part b)

When she will reach 25 m from band room

then total distance moved from cafeteria is

time taken by her

Part c)

Since Odina is moving at constant speed

so the position time graph must be a straight line graph

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
