The best technique to separate an insoluble solid from a liquid is filtration. Filtration is a process that separates solids from liquid by adding a medium, such as a filter paper, that only liquid can pass, and what is left behind the filter paper is the insoluble solid.
Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects. And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects. Electrical forces are extremely sensitive to distance.
<span>Air pressure is gravity pulling down on air molecules. Like us,
air has also mass and the pressure is brought down by the earth’s gravity
causing an increase in weight exerted on you as you descend lower into the
atmosphere. So, as you enter into the other layers of atmosphere above the troposphere,
the air pressure starts to decrease. <span>Below the atmosphere is the hydrosphere. This is
where all liquid forms are located. And since the seawater has a greater mass
than air, it has the greatest pressure. The answer is true.</span></span>
Answer:
166 666 666.7 years
Explanation:
We start the question by making the units uniform. We are told that the continents move at 3 cm/year = 0.03 m/year.
We are also told that the continents are now 5000 km = 5 000 000 m apart
So to calculate the time it took for them to be this far apart
t = distance/speed
t = 5 000 000 m/(0.03 m/year) = 166 666 666.7 years
Answer:
force=mass × acceleration
8=2 × acceleration
acceleration= 8/2= 4 m/s²
