A body is moving with an acceleration of 60 m/s2. If the force applied to t body is 42000 N, calculate its mass

Explanation:

Fnet = ma

m = Fnet/a = 42,000N/(60m/s²) = 700kg.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
