Where will you locate on a pendulum or roller coaster the greatest potential and greatest kinetic energy?
On a pendulum, the greatest potential energy is at the highest point of the swing on either side, and the greatest kinetic energy is at the bottom of the swing. On a roller coaster, the greatest potential energy is at the top of a hill, and the greatest kinetic energy is at the bottom of the hill.

Is Sound listen greater in solids or in air?
Sound velocity is greatest in solids, and the solid with the highest velocity of sound is metallic Beryllium.
What mineral would a patient of bulimia nervosa be most likely to lose in the greatest amount?
Magnesium and potassium.
Why does magnesium have the greatest number of nuclear charge in period 3?
The element Magnesium has two charges. The element Magnesium has two charges.
When should you take magnesium supplements?
Magnesium is a mineral so it shouldn't be taken on an empty stomach. That said, each product is designed differently. Some 'once a day/all in one' products don't really have the greatest source of magnesium or it's in the wrong form, so I take a stand alone magnesium product at the same time I take my calcium.

When magnesium burns air what substance is formed?
When magnesium ribbon is burnt in air, magnesium oxide is the main product. Equation 1 Eqn 1. 2Mg + O2 -----> 2MgO However, as there are traces of moisture in the air, a small amount gets converted to magnesium hydroxide Equation 2. Eqn 2. MgO + H2O -----> Mg(OH)2 And finally, because of the high temperatures involved the magnesium can also react with the nitrogen in the air to form traces of magnesium nitride equation 3. Eqn 3. 3Mg + N2 -----> Mg3N2 To reiterate, magnesium oxide is by far the greatest product.
What is a salinity gradient map?
Just breaking down the words, here's a reasonable guess. Salinity is having salts. Gradient is different amounts. A map would show you where. So I guess you are looking at where the greatest amount of salts are concentrated and where there are less or even which salts are where, if there is more than one kind available. Remember sodium chloride (table salt) is not the only salt; there is magnesium salts such as Epsom salts and many other alkaline metal salts I can't name. I don't remember my high school chemistry that well.
What is the best soil for cabbage?
Cabbage handles a variety of soils. But it grows best on well-drained loam soil that has adequate amounts of organic matter, and air and water pore spaces. A more alkaline pH, at 6.5-7.0, gives the greatest yields.
