Which segments of a seven-segment LED should be lighted on to display the digit ‘1’?
Segments B and C
Seven-Segment LED Display Basics
A seven-segment display is a widely used electronic component designed specifically for displaying numerical digits. It consists of seven individual light-emitting diodes (LEDs), which are typically arranged in a specific pattern and labeled with letters from 'A' through 'G'. These segments allow for the formation of digits 0-9 and some characters.
The standard configuration and labeling of these segments are as follows:
- Segment A: The top horizontal bar.
- Segment B: The top-right vertical bar.
- Segment C: The bottom-right vertical bar.
- Segment D: The bottom horizontal bar.
- Segment E: The bottom-left vertical bar.
- Segment F: The top-left vertical bar.
- Segment G: The middle horizontal bar.
Displaying Digit '1' on Seven-Segment LED
To accurately display the numerical digit '1' on a seven-segment LED, specific segments must be activated or "lighted up". Based on the standard layout, the digit '1' is formed using the two vertical segments located on the right side of the display.
These particular segments correspond to:
- Segment B (the top-right vertical segment)
- Segment C (the bottom-right vertical segment)
By illuminating only segments B and C, the seven-segment display will correctly show the digit '1'.

A stone is thrown horizontally from the top of a 20 m high building with a speed of 12 m/s. It hits the ground at a distance R from the building. Taking g = 10 m/s2 and neglecting air resistance will give :
A sphere of volume V is made of a material with lower density than water. While on Earth, it floats on water with its volume f1V (f1 < 1) submerged. On the other hand, on a spaceship accelerating with acceleration a < g (g is the acceleration due to gravity on Earth) in outer space, its submerged volume in water is f2V. Then:
A railway wagon (open at the top) of mass M1 is moving with speed v1 along a straight track. As a result of rain, after some time it gets partially filled with water so that the mass of the wagon becomes M2 and speed becomes v2. Taking the rain to be falling vertically and the water stationery inside the wagon, the relation between the two speeds v1 and v2 is :

1. Distance between the longitudes becomes zero on North Pole and South Pole.
2. Distance between the longitudes is maximum on the Equator.
3. Number of longitudes is more than number of latitudes.
Which of the statements given above is/are correct?
One block of 2⋅0 kg mass is placed on top of another block of 3⋅0 kg mass. The coefficient of static friction between the two blocks is 0⋅2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as 10 m/s2, the maximum value of the frictional force is :
