Answer:

records and traces of online activities of users are called carbon trail. (true). (false)

Answer 2

Answer:

Explanation:

RAM : 20cm

PLUNGER : 3CM

WEIGHT : 30KN

F1  :  ?(x)

  we have

Fram = Fplunger

A ram     Aplunger

or, 30 = x X (20/3)^2

or, 30KN=x X 44.44

or, 30/44.44 = x

or,x=0.68KN

therefore,FORCE REQUIRED(F1)=0.68KN
