The given statements are :
Q1) Distance formula is displacement/time T/F?
- False
Q2)velocity formula is = displacement/time T/F?
- True
Answer:
2.0 Hz
Explanation:
2.0 Hz is the most closest to the middle number in between 2.8 and 1.5 Hz. 1.6 Hz would not be suitable as it is too close to 1.5 Hz and 2.7 would also not be suitable as it is too close to 2.8 Hz.
Answer:
Option B) It decreases as someone moves away from earth's surface.
Explanation:
The atmospheric pressure at the surface of the earth is at maximum, it is seen that as we move away from the surface of the earth the pressure decreases. As on the top of mountains the atmospheric pressure is found to be low as compared to the surface of the earth.
It is assumed that the atmospheric pressure is caused due to hydrostatic measurements where the changes caused by weight of air are measured.
Also, it is observed that when there is an elevation, the atmospheric pressure decreases.
