How many millimetres (equivalent depth) of water are
contained in a soil profile 1 metre deep if the mass water
content of the upper 400 mm depth is 15% and that of the
lower 600 mm is 20%. The bulk density in the upper layer is
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
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 soilThe 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 soilHeight 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.

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

The question and answer choices are in the picture. THIS EXAM IS BEING TIMED SO I NEED ANSWERS, NOT LINKS, ASAP!!
Answer:
30 units of energy will be available to primary predators.
Explanation:
Using 10 % law i.e at each step 10 % of energy is transferred to the next trophic level at the rest of either consumed or lost to environment..
so plants have = 3000 units
herbivores = 10% of 3000 = 10/100 × 3000
= 300 units
so primary predators will have = 10% of 300
= 10/100 × 300 = 30 units
