Answer and draw properly!
Please screenshot it and draw it there, after that please post the picture here, Thank you in advance!
These are the instructions.
1. Draw a dashed lines across the graph to show where
S-wave velocity changes suddenly.
2. Label each of the zones between the line to show how
S-wave velocity changes, for example write ‘wave velocity decreasing’.
3. Draw a dotted line on the graph for the area deeper than 2900 km to show where P-wave velocity changes.
4. Label on the graph above each of the zones from 2900 km to 6400 km to show how P-wave velocity changes,
for example write ‘wave velocity decreasing suddenly’
or ‘wave velocity increasing gradually’.

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
