Weight = mass × gravity
Earth:
W = 70 × 9.8
= 686 Newtons
Carson’s <span>“Silent Spring” influenced the
environmental movement </span>as it presents a view of nature compromised by synthetic pesticides,
especially DDT. The pesticides not only kill bugs but also threaten bird and
fish populations, and eventually sicken children. Much of the data and case
studies that Carson drew from weren’t new but she was the first to consolidate
them all for the general public and to draw blunt conclusions. This book was so
revolutionary that by the end of the twentieth century, it took its place on
lists of the best books of the century or even of all time.
p=mv
where p=momentum, m=mass and v=velocity.
Hence momentum is the combination of mass and velocity.
