What forces are acting on a book lying on the table? Are action-reaction forces involved in this situation?

Answers

Answer 1

Answer: There is a weight force acting on the book downwards. There is a normal contact force also on the book upwards. These are equal and opposite. These two force are NOT an action-reaction couple (they are different types, they both act on the book)

Which pair of terms best describes a wooden table?

Answers

The answer is:

A) Biotic and non living

The explanation:

when Biotic refers to the component of living things that are part in ecosystem. Nonliving meaning a certain thing or the table does not have any life but it's biotic.

and we here have a wooden table that is derived from a living thing like a tree and it is nonliving as its a table.

what variables affect the acceleration of an object and in what matter do they affect the acceleration?

Answers

The variables that affect the acceleration of an object are

-- the object's mass
and
-- the net force acting on the object.

Acceleration = (net force) divided by (mass) .

The more mass an object has, the less acceleration it will have
in response to the same net force.

The more net force acts on an object, the more acceleration
the object will have.

Which of the following actions or events did not contribute to the Dust Bowl? Farmers in the Central U.S. had plowed grasslands to grow food crops to feed the increasing human population. They left the fields plowed and bare in the winter months when crops were not grown, and this left the soil exposed to wind. A long drought in the 1930s left the exposed soil especially dry due to the lack of precipitation. With the advent of pesticides, minerals in the ground were leached.

Answers

The following cause that is notconsidered in the formation of a Dust Bowl is the lack of farmers in Oklahoma.The answer is letter B. in fact, the number of farmers increases due to thehigh grain prices of Worl War I that encourages farmers to plow millions ofacres of natural grass to plant wheat.

A snail can move approximately 0.30 meters per minute. How many meters can the snail cover in 15 minutes?

Answers

A snail can move approximately 0.30 meters per minute then it would cover 4.5 meters in 15 minutes.

What is speed?

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is a meter/second. The generally considered unit for speed is a meter per second.

As given in the problem a snail can move approximately 0.30 meters per minute and we have to calculate the distance covered in 15 minutes.

speed of the snail = 0.30 meters per minute

time = 15 minutes

distance covered by the snail = speed ×time

distance covered by the snail = 0.30 ×15

distance covered by the snail = 4.5 meters

Thus, the distance covered by the snail in the 15 minutes would be 4.5 meters.
