Mass × velocity = momentum
74 x 15 = momentum
The properties of the electrons of an atom are determined in large part by the number of protons presented in the nucleus of the atom
Answer:
Another name for light is ¨Electromagnetic Radiation, luminous energy, and/or radiant energy.¨
Explanation:
Light is the electromagnetic radiation that´s capable of causing a visual sensation and has wavelengths from about 380 to about 780 nanometres. Electromagnetic radiation includes Radio Waves, Microwaves <u>(used in microwaves)</u>, Infrared Radiation <u>(heat)</u>, Visible Light <u>(the colors we see)</u>, Ultraviolet <u>(the UV radiation that causes sunburns)</u>, X-Rays <u>(used in medical X-Rays)</u>, and Gamma Rays <u>(which can be used to treat cancer)</u>. Light waves are transverse waves because they only travel east or west, but their crests and troughs face north and south (if desplayed on a coordinate grid). They wouldn´t be longitudinal waves because these waves don´t have vertical crests and troughs.

Mg(s) + SnSO₄(aq) = MgSO₄(aq) + Sn(s)
Mg + Sn²⁺ + SO₄²⁻ = Mg²⁺ + SO₄²⁻ + Sn
Mg + Sn²⁺ = Mg²⁺ + Sn
