organisms and water

Explanation:

Organisms and water contribute to both chemical and mechanical weathering . A form of weathering known as biological weathering is a derivative of both chemical and physical weathering.

Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
Organisms are pivotal to both physical disintegration of rocks through their activities.
Through their metabolic activities, they also releases chemicals that are used for chemical weathering of rocks.

Water is essential for weathering. It is used in alternate freezing and thawing, a mechanical weathering process to break down rocks.

It is used in rock hydrolysis for chemical weathering.

satela [25.4K]

For the average speed, I multiplied 4.9 by 3 squared to receive 44.1, then divided that by 3 to receive 14.7 m/s. 4.9 X 4.9 X 4.9 = 44.1(Distance traveled / fall time)44.1 ÷ 3 = 14.7 m/s

For the speed at t = 3, I took the derivative of 4.9t2 to make it 2(4.9)t and then plugged in 3 to receive an answer of 29.4 m/s. derivative =2(4.9)t =2(4.9)3 =29.4 m/s

A 66-kg bicyclist (including the bicycle) accelerates uniformly from 0.50 m/s to 1.50 m/s, traveling 6.0m. What is the net force

FromTheMoon [43]

The net force acting on the bicyclist is 11.022 Newton.

Given the following data:

Mass of bicyclist = 66 kg

Initial velocity = 0.50 m/s

Initial velocity = 1.50 m/s

Distance traveled = 6.0 meters

To find the net force acting on the bicyclist, we would apply Newton's Second Law of Motion:

Mathematically, Newton's Second Law of Motion is given by this formula;

$Force = mass$ × $acceleration$

First of all, we would determine the acceleration by using the third equation of motion;

$V^2 = U^2 + 2aS\\\\1.5^2 = 0.5^2 + 2a(6)\\\\2.25 = 0.25 + 12a\\\\12a = 2.25 - 0.25\\\\12a = 2\\\\a = \frac{2}{12}$

Acceleration, a = 0.167 $m/s^2$

Now, we can find the net force acting on the bicyclist:

$Force = 66$ × $0.167$

Force = 11.022 Newton

Therefore, the net force acting on the bicyclist is 11.022 Newton.

Describe the difference between the three states of matter in terms of movement behavior at room temperature and how they intera

yuradex [85]

In solids, the atoms are closely bound to each other. The only movement possible for the atoms in this state of matter is vibration. Solids have a fixed shape. Therefore when they are put in a container, the solids remain in their initial shape.

In liquids, the atoms are loosely bound compared to atoms in solid. And the atoms are free to vibrate and to slide past each other. The liquids have fixed volume but have no fixed shape. Therefore, when they are poured into a container, their volume will be the same, but the liquid will take the shape of the container.

In gas, the atoms are very loosely bound. and the atoms are very free to vibrate and move through space. Gases do not have either fixed volume or a fixed shape. Therefore, when they are poured into a container they take the volume and the shape of the container.

Answer:

The current in the primary is 0.026 A

Explanation:

Using the formula

I1 = (V1/V2)*I2

we have

I1 = (6.4/120)*0.500

I1 = 0.026 A
