Explanation:
Downstream: you just sum the magnitude of the velocity vectors:
3km/h + 4km/h = 7km/h
Upstream: difference of the magnitudes of the velocity vectors, in absolute value:
|3km/h - 4km/h| = 1km/h
Conservation tillage practices help reduce soil erosion and maintain soil nutrient levels.
<u>Explanation:</u>
The approach that helps in the reduction of doing tillage practices and also reducing its frequency. this is done for obtaining certain benefits for both environment and economic. This mainly focuses on providing sustainability by leaving some plants remaining in the soil.
It aims in decreasing the emission of gases of greenhouse effects like carbon dioxide. Using these practices helps in reducing the erosion and runoffs. This will promote health of the soil because the nutrients are not take off form the soil due to soil erosion and runoffs.
the answer is false hope this helps :]
Answer:
Explanation:
= Distance between central maxima and first minimum
m = Order = 1
d = Thickness of hair
= Wavelength = 632.8 nm
L = Distance between light source and screen = 1.25 m
Width of central maximum is given by
Distance between central maxima and first minimum is given by
Since is small
The strand of hair is thick.
