I need help the question is. As a river flows downhill carrying sediment, what happens when the river widens and slows down. A:larger particles are picked up by the current B:smaller particles are picked up by the current C:the largest are deposited D:the largest particles are deposited

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.

d) a person who learns about the world by observing it.

explanation:

scientist are people who discover why and how things are done and made in the world.
