The principle of electromagnetic induction states that a potential difference (or electromotive force, EMF) is induced in a coil only when there is a change in the magnetic flux linked with the coil. This change in magnetic flux can be caused by relative motion between the coil and the magnetic field source (like a bar magnet).
B) (c) A coil and a bar magnet moving in the same direction with the same speed
Study the given graph and answer the question that follows.
The graph presents the total production of crops (in metric tonnes) in six different states/UTs of the country in the years 2021 and 2022.
In which pair of states/UTs is the ratio of total crop production for both the years 1 : 2?
Delhi and Uttar Pradesh
West Bengal and Madhya Pradesh
Delhi and Andhra Pradesh
West Bengal and Andhra Pradesh
To find the pair of states/UTs where the ratio of total crop production for the years 2021 and 2022 is 1:2, we need to analyze the given graph and calculate the ratios for each pair of states/UTs mentioned in the options.
From the graph:
For Delhi and Andhra Pradesh:
Recalculating to check for a 1:2 ratio:
C) Delhi and Andhra Pradesh
We need to find the total time taken for a boat to travel a certain distance upstream and then downstream. First, we'll use the given information (distance, time, and ratio of speeds) to find the actual speed of the boat in still water and the speed of the stream. Then, we'll calculate the upstream and downstream speeds. Finally, we'll use these speeds to find the time taken for each part of the journey and sum them up.
Define variables and use the given ratio:
Let the speed of the boat in still water be \(V_b\) km/hr and the speed of the stream be \(V_s\) km/hr.
Given the ratio \(V_b : V_s = 7 : 2\). We can write \(V_b = 7x\) and \(V_s = 2x\) for some constant \(x\).
Calculate upstream speed:
Upstream speed \(V_u = V_b - V_s = 7x - 2x = 5x\) km/hr.
Use the first journey's information to find \(x\):
The boat takes 21 minutes to go 12.6 km upstream.
Convert time to hours: \[21 \text{ minutes} = \frac{21}{60} \text{ hours} = \frac{7}{20} \text{ hours}\].
Using the formula \(\text{Speed} = \frac{\text{Distance}}{\text{Time}}\):
\[ V_u = \frac{12.6 \text{ km}}{\frac{7}{20} \text{ hours}} \]\[ 5x = \frac{12.6 \times 20}{7} \]\[ 5x = \frac{252}{7} \]\[ 5x = 36 \]\[ x = \frac{36}{5} = 7.2 \]Calculate actual speeds:
Speed of boat in still water \(V_b = 7x = 7 \times 7.2 = 50.4\) km/hr.
Speed of stream \(V_s = 2x = 2 \times 7.2 = 14.4\) km/hr.
Calculate upstream and downstream speeds for the second journey:
Upstream speed \(V_u = V_b - V_s = 50.4 - 14.4 = 36\) km/hr.
Downstream speed \(V_d = V_b + V_s = 50.4 + 14.4 = 64.8\) km/hr.
Calculate time for the upstream part of the second journey:
Distance upstream = 43.2 km.
\[ \text{Time}_{\text{upstream}} = \frac{\text{Distance}_{\text{upstream}}}{V_u} = \frac{43.2}{36} = 1.2 \text{ hours} \]Calculate time for the downstream part of the second journey:
Distance downstream = 38.88 km.
\[ \text{Time}_{\text{downstream}} = \frac{\text{Distance}_{\text{downstream}}}{V_d} = \frac{38.88}{64.8} = 0.6 \text{ hours} \]Calculate total time:
Total time = \(\text{Time}_{\text{upstream}} + \text{Time}_{\text{downstream}} = 1.2 + 0.6 = 1.8\) hours.
D) 1.8
The total time taken for the boat to go 43.2 km upstream and 38.88 km downstream is 1.8 hours.
