Quartzite is produced when grains of quartz in sandstone are welded together when the rock is subjected to high temperatures. Quartzite<span> or Quarzit is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. </span><span>It is formed when a quartz-rich sandstone is altered by the heat, pressure, </span>
Answer:
Weight (mass) = 16.5 kg
velocity = 0 m/a
acceleration =2.6 m/s^2
displacement = 13.2m
now,
acceleration = velocity/ time
2.6 = 0 / t
t = o / 2.6
t = o
