Answer:

The correct answer is - all the options.

Explanation:

Any water that is used by humans or affected by humans is termed as wastewater. It includes water that comes from domestic households, agricultural and industrial water that can lead to pollution to the lakes, rivers, and other water bodies.

Lady_Fox [76]

Answer:

phototropism

Explanation:

The student was investigating phototropism.

The student wanted to know the response of the roots to light, that is why he exposed them to light.

Roots naturally exhibit two types of tropisms.

The first is gravitropism whereby they tend to grow downwards.

The second is hydrotropism whereby they grow towards the direction of water.

In the above experiment, no water was provided, the roots grew away from the light source but not specifically downwards.

Ryan hit a baseball with an acceleration of 20 m/s2. The mass of the baseball is 0.5 kg. What is the force?
AleksAgata [21]
Well to find the answer for force, the formula is mass X acceleration.
So, 20m/s² X 0.5kg = 10kg-m/s².
But, because we measure force in Newtons, we have to change the units (kg/m/s²) to Newtons.
1N (newton) equals to 1kg-m/s² and because we had 10, your answer is 
10N
