Answer:
Option A
Explanation:
Options -
A-avoid water pollution.
B-build thermal power plants.
C-add water features to gardens.
D-avoid drip irrigation systems
Solution -
The largest source of freshwater on planet earth is underground water. The water beneath the surface of earth is very limited. The total fresh water reserve on earth is 3% of the total water on earth. Pollution due to discharge of waste water into the rivers and oceans has caused the degradation of not only surface water but also ground water.
Thus, option A is correct
Drip irrigation is a means to prevent wastage of water during irrigation. Thus, avoiding it will cause further loss of fresh water.
Addition of water feature will increase usage of water, thus it is also incorrect
Building thermal plant will also cause water pollution and wastage. Hence, option B is also incorrect
Trichomes increase the chances of survival for plants living in areas with infrequent rainfall.
If a plant in a very rainy place had trichomes, it would probably adapt and remove them as time passed as they are unnecessary.
Solve the
potential energy at point B
PE = mgh
Where m is
the mass
G is the
acceleration due to gravity 9.8 m/s2
H is the height
PE = ( 1.5
kg) ( 9.8 m/s2) (0.5 m)
PE = 7.35 J
Solve the
velocity using the
KE = 0.5mv^2
Where ke is
the kinetic energy
M is the
mass
V is the
velocity
Since all
energy is converted to KE
So KE = PE
7.35 = 0.53(1.5)
v^2
V = 3.13 m/s
