Answer:
landslide
Explanation:
Landslide is one of the natural disasters in which the downward movement of the soil and rocks takes place. This results in the massive loss of life and property if happens in the populated area. Heavy rainfall is one of the reasons that trigger landslides. The soil absorbs a lot of moisture and gains a huge weight. This leads to the flow of soil in the downward direction. The earthquake also leads to landslides. The given description describes the landslide.
By using a woodstove, the kilograms of wood required to
heat a room to 20°C is 3 kg
<h3>Efficiency of a machine</h3>
- Efficiency is the percent of work put into a machine (input work) to that of the work done by the machine (output work).
- Efficiency of a machine is always less than 100% because the output work is always less than the input work because some of the input work is used to overcome friction.
Efficiency = work output/work input * 100%
Efficiency of fireplaces = 15%
Amount of food required to heat a room to 20°C = 15 kg
Assuming efficiency of 100%, amount of wood required will be X kg:
X = 15% * 15 kg
X = 2.25 Kg
By switching to woodstoves which are 75% efficient, amount of wood required will be Y kg:
Y = 2.25 kg / 75%
Y = 3 kg
Therefore, by using a woodstove, the kilograms of wood required to
heat a room to 20°C is 3 kg

The 2ed one!!! i have it and love it! it is the best!
<span>A vintage psychrometer measures humidity and humidity is measured by percentage. I hope this helps.</span>
