How many millimetres (equivalent depth) of water are

1300 kg m- and in the lower layer is 1500 kg m-?. Assume Pw
= 1000 kg m’How much water does the soil contain (in
cubic
metres) per 1.5 hectares of land?
ri

Answers

The equivalent depth of water in the soil is 180 mm of water and the volumetric water content of soil is 3870 cubic meter/ 1.5 hectare of soil.

What is the formula to calculate the equivalent depth of water in a soil?

The equivalent depth of water in a soil is calculated using the formula below:

equivalent depth of water = water content × depth of soil

The depth of soil profile 1 = 400 mm

The depth of soil profile 2 = 600 mm

Equivalent depth of water in the soil = 15% × 400 mm + 20% × 600 mm

Equivalent depth of water in the soil = 60 mm + 120 mm = 180 mm

Therefore, the equivalent depth of water in the soil is 1800 mm of water.

The volumetric water content of the soil is calculated using the formula below:

Volumetric water content = water content × bulk density of soil/density of water × height of soil

Height of soil profile 1 = 0.4 m

Height of soil profile 2 = 0.6 m

Volumetric water content of soil profile 1 = 15% × 1300/1000 × 0.4 m = 0.078 cubic meter/square metre of soil

Volumetric water content of soil profile 2 = 20% × 1500/1000 × 0.6 m = 0.18 cubic meter/square metre of soil

Sum of volumetric water content of soil = 0.078 + 0.18 = 0.258 cubic meter/square metre of soil.

1 hectare = 10000 square metre

Thus, 1.5 hectares = 15000 square metre

Volumetric water content of soil = 0.258 × 15000 cubic meter/ 1.5 hectare of soil

Volumetric water content of soil = 3870 cubic meter/ 1.5 hectare of soil

Thus, the equivalent depth of water in the soil is 180 mm of water and the volumetric water content of soil is 3870 cubic meter/ 1.5 hectare of soil.

Answers

Answer:

The angiosperms

Explanation:

Angiosperms are flowering plants. This is by far the most diverse group of plant species currently on Earth. Seedless vascular plants are things like ferns. Non-vascular plants are short and live in damp areas, like mosses. Gymnosperms are pine trees and related species, and gemetophytes isn't a group of plants, but part of the reproductive cycle of plants.

Question:9. What type of weather front would be responsible for the following forecast: “A period of heavy rain within the next 24 hours followed by warmer temperatures. Thunderstorms and possibly thundersnow from the period of 24 to 30 hours from now with temperatures dropping by 20-25˚ F and barometric pressure dropping by 15-20 mb. Snow beginning 30-36 hours from now, accumulation of 10-13 inches possible. Cooler temperatures and clear skies in 2 days.”

Answers

The type of climate front would be responsible for the forecast is a warm front followed by a cold front.

Hot front

A warm front has warm, moist air behind it. This warm air rises above the cold air because it is less dense and forms clouds along the front. As the warm front approaches, there is a greater drop in pressure and cloudiness, the temperature remains constant or rises slowly, unless it drops a little because of the rain.

Cold front

In a cold front, warm air is pushed out and replaced by cold air. As in the case of the warm front, the vertical structure of the hot air will determine the reactions with reference to cloudiness and precipitation. As a common cold front approaches there is heavy rain and there may be strong gusts of wind or violent storms. With the passage of the front, there is an increase in pressure, a sudden and large drop in temperature, an increase in the strength of the wind and a variation in its direction.

Whit this information ,we can conclude that the type of climate front would be responsible for the forecast is a warm front followed by a cold front.

What is the function of spines on cacti

Answers

The spines of the cactus have several functions, which are the following:

To defend them from possible predators: inside the body of the plants there is a great deal of water; if herbivores could access it, these plants would not survive.

To provide them with shade: it is true that not much, but it is enough so that the loss of water by evaporation is minimal.

Reflect sunlight: many species have white spines.

Water has many of its properties and can act as a major liquid in our bodies due to its high specific heat. However, if water had a LOW heat capacity, its ability to serve as a liquid to maintain homeostasis would be altered. A student makes several claims about the impact the altered heat capacity would have on its properties. Which of these claims would NOT be supported by the change in specific heat capacity of water?

Answers

The claim which would not be supported by the change in specific heat capacity of water include reduction in body temperature and dehydration.

What is Specific heat capacity?

This is defined as the quantity of heat needed to raise a substance's temperature by 1 degree Celsius.

If water has a low specific heat capacity then the body temperature will increase which will lead to an increase in dehydration.
