Geographers frank and deborah popper have proposed that in the future, much of the great plains should be taken out of agricultural production and instead used for what?
a. a separate homeland for native americans
b. a huge grassland habitat for restored herds of buffalo
c. to open the area up for the mining of oil from deep shale reserves
d. for the development of wind farms.
consider the upward direction of motion as positive and downward direction of motion as negative.
a = acceleration due to gravity in downward direction = - 9.81
v₀ = initial velocity of runner in upward direction = 2.0
v = final velocity of runner at the highest point = 0
x = distance by which center of mass of runner rise = ?
using the kinematics
v² = v²₀ + 2 a x
inserting the values
0² = 2² + 2 (- 9.81) x
x = 0.204 m
answer: the sound intensity was reduced by -14.77 db.
the level of the intensity of the sound with respect to the reference value is called sound intensity level.
i = intensity of the sound
= reference sound intensity
according to question, sound-reflecting windows that reduce the sound intensity level by 30.0 db .
let the intensity of the sound be and reduced intensity be i.
the sound intensity was reduced by -14.77 db.
thing is the answer jk
it is the name for a solid formed in a chemical reaction
