Acube has a density of 1800 kg/m3 while at rest in the laboratory. what is the cube's density as measured by an experimenter in the laboratory as the cube moves through the laboratory at 84.0 % of the speed of light in a direction perpendicular to one of its faces? you may want to review

3317.44401 kg/m³

Explanation:

= Actual density of cube = 1800 kg/m³

= Density change due to motion

v = Velocity of cube = 0.84c

c = Speed of light =

Relativistic density is given by

The cube's density as measured by an experimenter in the laboratory is 3317.44401 kg/m³

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

the answer is kevlar
