Answer:162.516 gm
Explanation:
Given
Quartz contains 46.7 % silicon by mass
i.e.Silicon is 46.7 % by mass
Total mass of Quartz m=348 gm
46.7% of 348 gm
Answer:
Just as distance and displacement have distinctly different meanings (despite their similarities), so do speed and velocity. Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time. Contrast this to a slow-moving object that has a low speed; it covers a relatively small amount of distance in the same amount of time. An object with no movement at all has a zero speed.
REALISM shows things as they REALLY look.
