Answer 1

Answer:

hello

Explanation:

1)acceleretion

)wave length

) mass density

specific volume

2)9.461 × 1015 metres

3) πr2h

4) To find the density of any object, you need to know the Mass (grams) of the object, and its Volume (measured in mL or cm³). Divide the mass by the volume in order to get an object's Density.

5) The liquid in which iron balls sinks is mercury.

6) speed and time d=st

The astronomical unit is used primarily for measuring distances within the Solar System or around other stars. It is also a fundamental component in the definition of another unit of astronomical length, the parsec.

...

7) The exact relationship is density = mass or weight divided by volume. Different materials have different densities. For example, the mass density of gold is 19.3 g/cc, lead is 11.4 g/cc, copper is 9.0 g/cc, aluminum is 2.7 g/cc, water is 1.0 g/cc (1g/cc = 1 gram per cubic centimeter).
