The volume of a sample of copper of 98.2 g would be 10.95 ml if the density of copper is 8.96 g/mL.
It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.
Due to their superior electrical and thermal conductivities, remarkable resistance to corrosion, and simplicity of production, copper alloys are frequently employed. In general, copper alloys are not magnetic. Electrical wire, cable, contacts, and other components.
As given in the problem the density of copper is 8.96 g/mL, and we have to find the volume occupied by the sample of copper.
mass = density×volume
98.2 g = 8.96 g/mL×volume
volume =98.2/8.96
=10.95 ml
Thus, the volume of a 98.2 g sample of copper would be 10.95 ml.

Answer:
Density=mass/volume.
8.96=98.2/volume.
volume=98.2/8.96=10.95982143 ~ 11cm^3.
Answer: Milankovitch cycle
Explanation: Every 100,000 years, the Earth's orbit becomes more elongated. this change in orbit has caused past ice ages and is called a Milankovitch cycle.
According to Milutin Milankovitch, the Milankovitch cycle explains the effect of the change in the earth's climate over thousands of year.
Answer:9.82 m
Explanation:
As we know from equation of motion
S=v*t +0.5 a t^2
Know s=H/2
a =9.82
t=1
V=0
Plugging the values
H*0.5=0+0.5*9.82*1^2
H=9.82 m
