<u>Answer:</u>

Planting multiple crops  on a field and harvesting their products  at different times is example of sustainable use of natural resources.

<u>Explanation:</u>

Sustainable use of natural resources refers to the use of natural components present in biological diversity at such a rate that the natural resource doesn’t get depleted. Also, the goal of the sustainable use of natural resources is to safeguard the natural resources for the current and future generations.

So planting multiple crops and harvesting them at different stages is a sustainable process. During this process, the natural resources are not over-utilised rather it is replenished back into the environment. This process also produces more yield from a limited area of farmland. For example, we can do banana plantation along with coconut farming. Here we can harvest both banana products and coconut products.

A very slow motion of earth's axis that requires 26,000 years to complete is called ________.
agasfer [191]

The answer is axial precession. Axial precession refers to the very slow motion of the Earth’s axis, which almost requires twenty-six thousand (26,000) years to complete a full rotation. This Axial Precession is caused by the effects of gravitational pull from the Sun and the Moon towards the Earth.

Please help me:)
Alenkinab [10]

Answer:

The correct option is;

Sphere I is positively charged and sphere II is negatively charged

Explanation:

The charging of the spheres by induction is achieved by introducing a charge to the metal spheres that are insulated from the ground to prevent loss of charge by placing them on insulating stand

The two spheres are brought into contact by the connection of a conducting wire between the spheres I and II

The presence of the positively charged sphere III draws attracts electrons towards sphere II while the net positive charge moves towards sphere I

While the spheres I and II are still polarized, the conducting wire is removed  while the presence of sphere III continues to keep sphere II negative compared to sphere I

After removing the connecting wire, sphere III is removed leaving the excess negative charge on sphere II and the excess positive charge on sphere I

The net charges then evenly redistribute themselves on each sphere creating two oppositely charged spheres.

A 50.0-g ball traveling at 25.0 m/s bounces off a brick wall and
liubo4ka [24]

Answer:

13,400 m/s²

Explanation:

Average acceleration is the change in velocity over time:

a = Δv / t

a = (22.0 m/s − (-25.0 m/s)) / 0.00350 s

a = 13,400 m/s²
