To find the total energy consumed, we need to calculate the energy consumed by each appliance (heater and geyser) separately and then sum them up. The energy consumed is calculated by multiplying the power rating by the time of use. Since the power is given in Watts (W) and we need the energy in kilowatt-hours (kWh), we must convert Watts to kilowatts (kW) and then multiply by the time in hours.
Power of electric heater (\(P_H\)) = 1000 W
Power of electric geyser (\(P_G\)) = 2000 W
Total power (\(P_{\text{total}}\)) = \(P_H + P_G = 1000 \text{ W} + 2000 \text{ W} = 3000 \text{ W}\)
Since \(1 \text{ kW} = 1000 \text{ W}\),
\[ P_{\text{total}} = \frac{3000 \text{ W}}{1000 \text{ W/kW}} = 3 \text{ kW} \]Both appliances are used for 4 hours daily.
Daily usage time (\(T_{\text{daily}}\)) = 4 hours
Energy consumed per day (\(E_{\text{daily}}\)) = Total power \(\times\) Daily usage time
\[ E_{\text{daily}} = P_{\text{total}} \times T_{\text{daily}} = 3 \text{ kW} \times 4 \text{ hours} = 12 \text{ kWh} \]Total energy consumed (\(E_{\text{total}}\)) = Energy consumed per day \(\times\) Number of days
\[ E_{\text{total}} = 12 \text{ kWh/day} \times 10 \text{ days} = 120 \text{ kWh} \]A) 120 kWh is the correct energy consumed in 10 days.

As of March 2022, Justice Nuthalapati Venkata Ramana (N.V. Ramana) was serving as the 48th Chief Justice of India. He assumed office on April 24, 2021, and retired on August 26, 2022.
Correct Option: B) NV Ramana
Justice NV Ramana was the Chief Justice of India from April 24, 2021, to August 26, 2022. Therefore, he was the CJI in March 2022.
In the given reaction, ________ acts as a reducing agent.
Fe2O3 + 3CO → 2Fe + 3CO2
To identify the reducing agent in a redox reaction, we need to determine which species undergoes oxidation. Oxidation is the loss of electrons or an increase in oxidation state. Conversely, reduction is the gain of electrons or a decrease in oxidation state. The reducing agent is the species that gets oxidized and causes another species to be reduced.
The given reaction is:
\[ \text{Fe}_2\text{O}_3 + 3\text{CO} \rightarrow 2\text{Fe} + 3\text{CO}_2 \]The reducing agent is the substance that gets oxidized. In this reaction, Carbon in CO is oxidized (from +2 to +4). Therefore, CO acts as the reducing agent.
Correct Option: B) CO acts as the reducing agent because its carbon atom's oxidation state increases from +2 to +4, meaning it undergoes oxidation.
The question asks to identify the Article of the Indian Constitution that mandates the organization of village panchayats as units of self-government, as a Directive Principle of State Policy. This requires knowledge of the specific Articles related to Directive Principles and their contents.
Correct Option: B) Article 40 of the Constitution of India is the Directive Principle of State Policy that mandates the State to organize village panchayats and empower them to function as units of self-government. This Article reflects the Gandhian principle of village self-rule and was instrumental in the later constitutional recognition of Panchayati Raj Institutions through the 73rd Amendment Act.
This problem involves calculating the displacement from the starting point after a series of movements in different directions. We can solve this by breaking down the movements into components along the North-South and East-West axes.
Correct Option: D) 37 m. The final position is 37 m North of the starting point.
The question asks to identify the incorrect feature among the given options regarding alveoli. We need to recall the structural characteristics of alveoli that facilitate efficient gas exchange.
Correct Option: D) Are finger-like structures
Study the given letter series and answer the question that follows.
Q I O M J E S T R U L E B A C K J M N
How many consonants are immediately preceded by a consonant and immediately followed by a vowel?
The problem asks us to identify the number of consonants in a given letter series that satisfy two conditions: they must be immediately preceded by a consonant and immediately followed by a vowel. We need to go through the series letter by letter, identify consonants, and then check the letters immediately before and after them.
Correct Option: B) 2
A certain number of people are sitting in a row, facing north. D is to the immediate right of H. A is third to the left of C. Only three people sit between H and L. L is fifth to the right of C. D is at the extreme right end of the row. If no other person is sitting in the row, what is the total number of persons seated?
This is a linear arrangement puzzle. We need to deduce the positions of individuals in a row based on the given clues and then count the total number of people. We will start by placing the person whose position is fixed (extreme end) and then use relative positions to fill in the rest.
Clue 1: D is at the extreme right end of the row.
This means D is the last person on the right. Let's represent the positions from left to right.
... D
Clue 2: D is to the immediate right of H.
Combining with the first clue, H must be immediately to the left of D.
... H D
Clue 3: Only three people sit between H and L.
Since D is to the right of H, L must be to the left of H. There are three people between H and L.
L _ _ _ H D
Clue 4: L is fifth to the right of C.
This means there are four people between C and L, and C is to the left of L.
C _ _ _ L _ _ _ H D
Clue 5: A is third to the left of C.
This means there are two people between A and C, and A is to the left of C.
A _ _ C _ _ _ L _ _ _ H D
Final Arrangement:
Now, let's count the total number of positions based on the final arrangement:
A _ _ C _ _ _ L _ _ _ H D
Counting the positions:
The total number of people seated is 13.
Recheck the question and options.
Wait, there seems to be a discrepancy. Let's re-evaluate the counting carefully.
The arrangement is: A _ _ C _ _ _ L _ _ _ H D
Let's count the people and the spaces between them:
Total people = A + C + L + H + D = 5 people.
Total spaces = 2 + 3 + 3 = 8 spaces.
Total positions = Number of people + Number of spaces = \(5 + 8 = 13\).
Let's re-read the clue: "L is fifth to the right of C." This means there are 4 people between C and L.
C _ _ _ _ L (5th position for L relative to C)
Let's re-construct:
D (Extreme right)
H D (D is immediate right of H)
L _ _ _ H D (3 people between H and L)
C _ _ _ _ L _ _ _ H D (L is 5th to the right of C, meaning 4 people between C and L)
A _ _ C _ _ _ _ L _ _ _ H D (A is 3rd to the left of C, meaning 2 people between A and C)
Let's count the total number of positions in the final arrangement:
A (1) _ (2) _ (3) C (4) _ (5) _ (6) _ (7) _ (8) L (9) _ (10) _ (11) _ (12) H (13) D (14)
The total number of persons seated is 14.
B) 14. The step-by-step construction of the seating arrangement leads to 14 people in total.
