In physics lab, you measure three quantities: , , and . Suppose that =1.5 kg , =0.4 m , and =3.9 kg/m . Which of the mathematical combinations might be meaningful?

1.5 kg is mass, .4 m is volume, and 3.9 kg/m is volume

Explanation:

When looking at these types of problems, consider each part. First, whenever problems have measurements that have similar units of measurement, check if they are density related. In this case, we use the formula of D=M/V, where D stands for density, M stands for mass, and V stands for volume. Any measurements that relate to grams or pounds are mass. In solids, volume is written in cm or m, while in liquid, volume is considered in liters and gallons. Density is always mass divided by volume, so we know that 3.9 kg/m is the density due to the units provided.

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes
