I believe the answer is B. <span>Contour farming
</span>In <span>Contour farming , we put the plant on perpendicular method, and </span><span>tilling sloped the land along lines of consistent elevation.
</span>By Doing this, we will ensure that every part of the soil will receive proper amount of water from the rainfall, hence prevent the chance of soil loss from surface erosion.
Answer:6g/cm³
Explanation:density=mass/volume
D=30/5
Density of marble=6g/cm³
A heat engine is operating between 287 c and 32 c. if the engine extracted 400 mj of energy from fuel, 4109.6 Jews mj of energy could be used as mechanical energy
Using the temperatures, a heat engine's efficiency is determined (lowest and highest).
The ratio of the system's provided heat to the desired work is considered the system efficiency. An engine's efficiency ranges from 0 to 1.
The efficiency of the engine is 27%, or 0.27. Since the heat was turned down due to the 3000 gems, we must find productive employment. Heat input and network efficiency are connected. That is the line. Qc was rejected by two W plus heat, leading to Qh. The cost of networking is composed of Nita W and Nita Qc. The network completed is identical to Nita. Q C is split into two halves. As a result, we must divide our efficiency, which is 0.27, by 3000. The engine's work is represented by this. Let's calculate the result of 0.27 multiplied by 3000 divided by 1. 1109 and 0.6 gems are the answer. He rejected our quote, which is +110 9.6 plus three thousand. 4109.6 Jews is quite close to the heat input.

Answer:
3 days to get from earth to moon
Explanation:
The final velocity of the skateboarder I after the collision is 3 m/s to the left.
<h3>
Velocity of skateboarder I</h3>
The velocity of skateboarder I is determined from the principle of conservation of linear momentum.
m1u1 + m2u2 = m1v1 + m2v2
50(0) + 75(0) = 50v1 + 75(2)
0 = 50v1 + 150
v1 = (-150)/50
v1 = - 3
v1 = 3 m/s to the left
Thus, the final velocity of the skateboarder I after the collision is 3 m/s to the left.
