Newton's second law of motion
F = ma
Answer:
D - water changes from a
Explanation:
You're correct!
We are asked what happens when the pressure changes from 0 atm to 10 atm at 0C.
If we look at the graph at 0C on the x axis and at 0 atm on the y axis, we can see we are in the yellow area of the graph, so the water starts at a gas.
If we keep the temperature the same, but change the pressure to 10 atm (much higher on the y axis) we are in the blue area, so the water is now a liquid. Therefore, D is correct
The grand canyon is 884 m deep
<h3>Formula for velocity of echo</h3>
The velocity of an echo can be obtained by using the following formula
v = 2x / t
Where
- v is the velocity
- x is the distance
- t is the time
With the above formula, we can determine how depth the grand canyon. Details below:
<h3>How to determine the depth of the grand canyaon</h3>
- Velocity (v) = 340 m/s
- Time (t) = 5.2 s
- Depth (x) =?
v = 2x / t
340 = 2x / 5.2
Cross multiply
2x = 340 × 5.2
2x = 1768
Divide both sides by 2
x = 1768 / 2
x = 884 m
Thus, the grand canyon is 884 m deep
