(1) Filtration - example is separating saltwater from sand particles.
(2) Distillation - example is apple cider vinegar. Distillation collects the liquid that we want, which is the vinegar and leave out other heavier suspended particles.
(3) Centrifuges - example is separating the blood components. They separate the plasma and erythrocytes.
(4) Magnetism - example is separating metals from non-metals in electromagnetic cranes, that differentiate between metal and heap of junks.
The icy objects that mostly travel in long,elliptical orbits around the sun are known as COMETS.
A comet is a miniscule solar system body that is made up mostly of ices mixed with smaller amounts of dust and rocks. The main body of the comet is called and the nucleus which primarily contains water, methane, nitrogen and other ices.
Applying rule of thumb: For every 1000 m, temperature drops by 2 °C. If the ground temperature is room temperature at 20 °C, then:
At 6694 m, temperature = 20 - (6694/1000*2) = 6.6°C
Now,
H= (30t+8000)*ln (C/P), where H = Altitude, t = temperature, C = ground atmospheric pressure, say 101325 Pa, P is the pressure at the altitude.
Therefore,
6694 =(30*6.6+8000) ln (C/P) => 0.8165 = ln (1013255/P) => e^0.8165 = 101325/P => 2.2627 = 101325/P => P = 101325/2.2627 = 44781.39 Pa
Answer:
(a) Positive
(b) Electron gains energy as it moves from A to B.
Explanation:
VA = 260 V
VB = 210 V
An electron moves from lower to higher potential which is negatively charged and a positively charged particle moves from higher to lower potential, so the charge particle is positive in nature.
(a) Positive
(b) No, electron gains energy as it moves from A to B.
