I hope this helps
Answer:
1. Urea, (d)Fertilizer
2. Combines, (c) Harvesting and threshing
3. Silos, (b) Storage of grains
4. Seed drills, (a) Sowing seeds
5. Irrigation, (f) Sprinklers
6. Tilling, (e) Preparation of soil
Explanation:
1) Urea is a widely used and important fertilizer in the agricultural industry
2) The combine harvester combines three categories of harvesting grain drops such as threshing reaping and winnowing
3) Silos are used to store grains
4) A seed drill is a seed planting mechanism for burying seeds to a particular depth during seed planting
5) Irrigation is the application of required volume of water to plants
6) Tilling is the digging, turning, and staring operations meant to prepare the soil.
Because it eats plants and animals.
Answer:
voltage measured by the voltmeter = (E × RV)/(r + RV)
Explanation:
The circuit diagram for this description is presented in the attached image.
The internal resistance of an emf source is modelled to be in series with the source.
Therefore, the end product is a circuit with the battery in series connection with the internal resistance and resistance of the volunteer. The voltage picked up by the volunteer is the voltage across resistor RV.
Total resistance in the circuit = (r + RV) ohms (since both resistors are in parallel)
Current produced by the emf source = E/(Total resistance) = E/(r + RV)
The voltage across resistor RV = current flowing through this resistor × its resistance.
Since all the circuit elements are in series with each other, same current, E/(r + RV) flows through them all
Voltage across RV = voltage measured by the voltmeter = [E/(r + RV)] × RV = (E × RV)/(r + RV) = (E.RV)/(r + RV)
