Answer:
Total pressure =1.01*10^5 Pa
Explanation:
given data:
atmospheric pressure = 1.013 *10^5 Pa\
height of water column = 60 cm
Total pressure will be sum of atmospheric pressure and pressure due to water column
P = Atmospheric pressure + pressure due to water column
pressure due to water =
\rho of water = 1420 kg/m^{3}
height of water column = 60 cm =0.60 m

Total pressure = 109649.6 Pa = 1.10*10^5 Pa
Total pressure =1.01*10^5 Pa
The answer to your question is "science"
Explanation:
Given that,
A person walks 9.0 km directly east and then turns left and heads directly north for 12.0 km.
We need to find his displacement from the starting position.
We know that,
Displacement = shortest path covered

For direction,

Hence, this is the required solution.
Answer:
D. The primary source, because it was written by the researcher
Explanation:
One should learn to trust the primary source more because it is the real work of the researcher.
A primary work defines the work of research from his or her experimental findings.
- The primary source presents experimental data and other subordinates ones to reach a conclusion as seen from the view of the researcher.
- A secondary source implies someone else documenting their own opinion about the primary experimental set up.
- This can get dicey in the sense that results can be twisted to serve other ulterior motives.
Answer:
43.88 meters per second
Explanation:
The computation of the speed is shown below:
As we know that

where,
Distance is 395,000 meters
Time is 9,000 seconds
Now placing these values to the formula
So, the speed is

= 43.88 meters per second
As speed shows the relation between the distance and time and the same is to be considered i.e by applying the formula
