Weight is different (but mass is the same)
sorry Idk the answer ..???
Answer:
Explanation:
The volume charge density is defined by ρ = (Equation A), where Q is the charge and V, the volume.
The units in the S.I. are , so we have to express the radius in meters:
inner radius =
outer radius =
Now, we know that the volume of the sphere is calculated by the formula:
, and as we have an spherical shell, the volume is calculated by the difference between the outher and inner spheres:
V = , where is the outer radius and is the inner radius.
Replacing the volume formula in the Equation A:
ρ =
ρ =
Replacing the values of the outer and inner radius whe have:
ρ =
ρ =
Answer:As a rule sound travels slowest through gases,faster through liquids,and fastest through solids.The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour.Speed of light in water = 226 million m/s or 205,600 mph.
