Answer:

Decomposers

Explanation:

Decomposers are organisms that gives the soil essential nutrients for new plants to grow.

These are micro-organisms that takes up dead and decaying organisms. They break and reduce them down into useful soil organic matter.

Organic matter are the remains of plants and animals that are very vital in the soil. They provide nutrients needed for plant growth.

Complex organic molecules are broken down into simple and useful ones which are needed for the growth of plants.

Explanation:

Moments must be conserved - so.

$20 * 0.4 = F * 0.05$

$F=\frac{20*0.4}{0.05} = 160$

Identify the row that contains two scalars and one vector quantity: Distance Acceleration Velocity Speed Mass Acceleration Dista

GenaCL600 [577]

Answer:

Speed, mass and acceleration

Explanation:

A scalar quantity is a quantity that has only magnitude but no direction while a vector quantity has both magnitude and direction.

According to the question, the row that has two scalars and one vector is speed, mass and acceleration.

The two scalars in this row are speed and mass while the vector quantity there is the acceleration.

Acceleration has direction since it possess direction. A body accelerating will do so in a particular direction. Speed and mass doesn't possess any direction. Mass only specify the magnitude of the body but no clue as to which direction is the body moving towards.

Speed also only specify the

total distance covered with respect to time but not the direction of the direction.
