The answer is annual grass weeds.
Preemergence herbicides typically been the most effective and preferred to control the annual grass weeds. Preemergence herbicides are widely used to control the weeds that are grown in lawns and if we use this herbicides many weeks before the germination of weeds, it will be very effective.
They wanted freedom from the Church of England, which they believed to be wrong.
"<span>The Pilgrims were Puritans who escaped to Holland as political exiles in 1608. They immigrated to North America on the Mayflower in 1620. "Pilgrim" means a person who takes a long journey, usually for a religious or moral purpose; "Pilgrim" also is the popular term for all passengers of the Mayflower who sought religious freedom"

"<span>Puritan newcomers continued to think of themselves as English. They saw their new colony as a "city on a hill" which would set an example of biblical righteousness in church and state for the entire world to emulate. The Puritans emphasized especially the importance of community over individuality."</span>

Answer:
502.51 kg/m^3
Explanation:
Upthrust on object in water is 40 - 20 = 20 N
Upthrust is equal to the buoyancy forces given as
B = pgv
p is density of water 1000 kg/m^3
g = acceleration due to gravity 9.81 m/s^2
v is the volume of liquid displaced.
Therefore
B = 1000 x 9.81 x v
20 = 9810v
v = 2.038x10^-3 m^3
For Upthrust in unknown liquid, we have 40 - 30 = 10 N
Bouyancy force for the liquid will be
B = P x 9.81 x 2.038x10^-3
NB- the same volume of fluid will be displaced i.e 2.038x10^-3 m^3
Equating we have
10 = P x 9.81 x 2.038x10^-3
10 = 0.0199p
p = 10/0.0199 = 502.51 kg/m^3
