This shifts chemical equilibria toward the products or reactants, which can be determined by studying the reaction and deciding whether it is endothermic or exothermic....
Answer:
Great question! To solve this problem you just need a bit of simple math. The short answer is 60 m/s
Explanation:
To solve this, you must first set up your equation.
540km/2.5hr * 1000m/3600s
You would set it up this way because there are 1000 meters in a km and 3600 seconds in an hour. This
540000m/9000s
This simplifies down to
60m/s
If the sphere is positively charged, the positive rod is repelled by the sphere while the negative rod is attracted by the sphere.
<h3>What is an electrical charge?</h3>
An electrical charge can be positive or negative. From the laws of electrostatics, unlike charges attract while like charges repel. As such the effect observed when the rods are individually brought near the sphere will decide the charge on the sphere.
If the sphere is neutral, there is no effect observed when each rod is brought near the sphere. If the sphere is positively charged, the positive rod is repelled by the sphere while the negative rod is attracted by the sphere.

Answer:
From largest to smallest they are: Universe, galaxy, solar system, star, planet, moon and asteroid.
Explanation:
Answer: It is not gold. The density is 1.25 g/cm3, very little compared with gold.
Explanation:
According to Archimedes’ principle, any body submerged in a liquid, receives an upward force, called buoyant force, which magnitude is equal to the weight of the liquid that displaces.
This weight can be calcultated as follows:
Fb= δH2O . Vbody g
We are told that the volume of the liquid displaced (equal to the volume of the body as it is completely submerged in water) is 400 cm3.
If we know that the mass of the bracelet is 0.5 Kg, we can find out the density of the material, just applying the same relationship between mass, density and volume:
m = δbracelet. V
δbracelet = m / V = 500 g / 400 cm3= 1.25 g/cm3
As the gold density is approximately 19.3 g/cm3, it is clear that the bracelet is not made from gold, but from something less dense.
