Inclined planes reduce the amount of effort needed to move an object, but increases
QveST [7]

Inclined planes reduce the amount of effort needed to move an object, but increases the length of the ramp.

<u>Explanation:</u>

Mechanical advantage is the measure of amount of effort needed to move an object. The mechanical advantage can be calculated as the ratio of length of ramp to the height of ramp for an inclined plane.

As it is known that an object can be easily moved on an inclined plane than on a vertical plane, this is because, the inclined plane provides greater output force. But in that case, the effort required will be reduced with the cost of increasing the distance of the movement of object.

In other terms , the ramp's length of inclined planes has to get increased in order to reduce the amount of effort needed to move an object. This is because as the mechanical advantage has length of the ramp in the numerator, with the increase in numerator value or length value the mechanical advantage will also increase.

I need help asap!!!!
Butoxors [25]

Answer:

2H₂O₂ →  2H₂O + O₂

24.7 L are the liters of formed oxygen.

Explanation:

We state the reaction:

2H₂O₂ →  2H₂O + O₂

2 moles of peroxide decompose to 2 moles of water and 1 mol of oxygen gas.

We convert the mass to moles: 75 g . 1 mol / 34 g = 2.20 moles

As ratio is 2:1, per 2.20 moles of peroxide I would produce the half of moles, of O₂ → 2.20 /2 = 1.10 moles

We convert the moles to mass → 1.10 mol . 32 g / 1 mol = 35.3 g

Let's use oxygen's density to find out the volume

δ O₂ = 1.429 g/L    (mass/volume)

35.3 g . 1L / 1.429g = 24.7 L

It's something to do with the weathering process. Eg. At night it's really cold, and in the day it's really hot. Because the temperature keeps changing dramatically day in and day out, the sand dunes start to be sort of hacked or re-shaped, or even formed.
