The relative density of a substance is the ratio of its density to the density of liquid water, which is roughly 1000kg/m³
For example, the relative density of aluminum is 2.7, therefore it has a density of roughly 2700kg/m³
Answer:
We define a vector as an object with a length and a direction.With no length, the zero vector is not pointing in any particular direction, so it has an undefined direction.
Explanation:
Pls mark me brainliest :)
Answer: ssm An airplane with a speed of 97.5 m/s is climbing upward at an angle of 50.0° with respect to the horizontal. When the plane's altitude is 732 m, the pilot releases a package.
<span>From the
small number of impact craters on moon, planetary geologists suspect
that virtually all its original surface has been covered over by younger
volcanic activity</span>. Most
of the Moon's surface is densely covered with craters, but we find relatively few
craters within the lunar maria.<span> </span>
