The mass per unit volume of a substance is called __________.
astraxan [27]

Answer: Density

This measurement tells you how packed in a substance is. The higher the density, the more the object weighs for a certain volumetric unit (such as a cubic meter). Eg: a cubic meter of feathers is likely to weigh less than a cubic meter of solid gold because the feathers have a lot more air in them as opposed to the gold which is more compact.

density = mass/volume is the formula you often use

It is given that -7, h, k, 20,... are the first 4 terms of an arithmetic progression.
dexar [7]

Answer:

the answer should be B

Step-by-step explanation:

the first part is basically finding the difference between the terms, as we know that d=T2-T1

so by comparing the T2-T1 and T3-T2 we can find the difference with the two variables h and k

afterwards do the same with T4-T3 and T3-T2, comparing them and you will get another equation

now that you have two equations, you can do simultaneous equation to get the answers

hope i helped :D
