Answer:
If the Earth absorbs more insolation from the sun than it radiates back, the Earth. warms
Because polymers are covalently bonded material, and metals are metalicly bonded material.
Covalent bonds do not let atoms exchange electrons like metalic bonds do.
Answer: mass x height x gravitational field strength (g)
note: gravitational field strength (g) = 10 N/Kg
55 x 15 x 10 = 8250
gpe = 8250j
Explanation:
Answer:
Explanation:
Chemical properties only manifest when a chemical reaction occurs. Being reactive, flammable and explosive are chemical properties, because they involve chemical reactions: the substances are changed; the chemical bonds of some substances, called reactants, are broken, and the chemical bonds are created, forming other substances, called products.
Solubility is a<em> physical property</em> because during dissolution no new substances are formed. You can prove it when the solvent evaporates leaving behind the same original substance.
The the observation that the substance is <em>soluble</em> is describing a <em>physical property.</em>
Answer:
so this is nearly red colour light
Explanation:
As we know that the interference of light from reflected light then the path difference is given as
now we know that for constructive interference of light the path difference is given as
so we will have
so we will have
so this is nearly red colour light
