Answer:
Drip irrigation can reduce water use by 30 to 70 percent compared to conventional sprinkler irrigation. Sprinklers can waste water due to scattered spray from winds, evaporation, run-off or deep leaching. Healthier plants.
Explanation:
Answer:
The magnitude of the gravitational force acting on the lander on the surface of Mars is 512.46 N.
Explanation:
The Universal law of gravity is define as:
(1)
Where F is the gravitational force, G is gravitational constant, M is the mass of Mars, m is the mass of the lander and R is the radius of Mars.
Before replacing the values in equation 1 it is necessary to express the radius of mars in terms of meters:
R =
⇒ R = ![3397000 m](https://tex.z-dn.net/?f=3397000%20m)
Finally, equation 1 can be used:
![F = 512.46 N](https://tex.z-dn.net/?f=F%20%3D%20512.46%20N)
Hence, the magnitude of the gravitational force acting on the lander on the surface of Mars is 512.46 N.
When the tube feet contracts, the direction of water flow will be reversed.
