An object accelerates 5.0 m/s2 when a force of 12.0 newtons applied to it. What is the mass of the object? Please help, I haven’t seen this question anywhere !
Also this is from my Science Class

2.4kg

Explanation:

Newton's 2nd law tells us that force is equal to the mass of an object multiplied by its acceleration, or F = ma. We can solve this equation for mass by rearranging algebraically:

m = F/a

So:

m = (12.0N)/(5.0m/s2) = 2.4kg

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.
