The pressure exerted by a column of liquid of height h and density ρ is given by the hydrostatic pressure equation p = ρgh, where g is the gravitational acceleration.
p = ρghρ = 1000 kg/m3g = 9.81 m/s2convert mm h20 to Pa700 mm H20 ( 9.81 pa / 1 mm h2o)= 6867 Pa
6867 Pa = (1000 kg/m3)(9.81 m/s2)hh = 0.7 mh = 700 mm
C. Hypothesis
The hypothesis is presented as an explanation of the observed results.
Answer:
I gonna give you the number so but you need to round 6.19047619048
Explanation:
- This is a speed formula so you would use the formula speed=distance/time
- You need to rearrange it to time=distance/speed
- So you need to divide 13m by 2.1 m/s
When a liquid is cooled, the kinetic energy of the particles, DECREASES..
Answer:
The two forces that affect on the pendulum are the force of gravity,
Explanation:
- ⇒ There is the force of gravity that acts downward upon the bob. It results from the Earth's mass attracting the mass of the bob. And there is a tension force acting upward and towards the pivot point of the pendulum.
Therefore, I hope this helps!
