Answer:
They are formed on or near the Earth’s surface from the compression of ocean sediments or other processes.
Explanation:
Answer:
a. 192 m/s
b. -17,760 kPa
Explanation:
First let's write the flow rate of the liquid, using the following equation:
Q = A*v
Where Q is the flow rate, A is the cross section area of the pipe (A = pi * radius^2) and v is the speed of the liquid. The flow rate in both parts of the pipe (larger radius and smaller radius) needs to be the same, so we have:
a.
A1*v1 = A2*v2
pi * 0.02^2 * 12 = pi * 0.005^2 * v2
v2 = 0.02^2 * 12 / 0.005^2
v2 = 192 m/s
b.
To find the pressure of the other side, we need to use the Bernoulli equation: (600 kPa = 600000 N/m2)
P1 + d1*v1^2/2 = P2 + d1*v2^2/2
Where d1 is the density of the liquid (for water, we have d1 = 1000 kg/m3)
600000 + 1000*12^2/2 = P2 + 1000*192^2/2
P2 = 600000 + 72000 - 1000*192^2/2
P2 = -17760000 N/m2 = -17,760 kPa
The speed in the smaller part of the pipe is too high, the negative pressure in the second part means that the inicial pressure is not enough to maintain this output speed.
Answer:
(C) They consist of ice.
Explanation:
Comet consist of a body of ice, rock and dust that can be several miles in diameter and orbits the sun. Debris from comets is the main source of many meteoroids.
Harper used the the frequency principle (F) by planning to work out 4-5 days a week. Frequency is how often you exercise, usually on a weekly basis.
She used the intensity principle (I) by deciding to exercise on a moderate level, rather than, for example, an intense workout. Intensity is basically how hard you exercise and push yourself.
She then used the time (T) principle by choosing to workout for 60 mins per day. Time meaning how much time you spend working out each day.
And lastly, she used the type (T) principle by devising a specific type and/or set of exercise(s) to do, which in her case, is drills, jogging, and weight lifting.
So all in all, Harpers frequency is 4-5 days per week, her intensity is moderate, her time is 60 mins/day, and type is basketball drills, jogging and weight lifting.
Hope I helped! :)
The answer is: 12.30 degrees.
To solve this problem you must apply the proccedure shown below:
1. You run 22 meters horizontally and then you climb a rope vertically for 4.8 meters.
2. So. let's call the angle 
, therefore, you must find it using 
, as following:
3. Substitute values and solve for the angle:
