Share & grow the world's knowledge!
We want to connect the people who have knowledge to the people who need it, to bring together people with different perspectives so they can understand each other better, and to empower everyone to share their knowledge.
In a simple microscope a convex lens of focal length 5 cm is used. Calculate the magnifying power when the object is placed at the focus of the lens.
For a simple microscope, when the object is at the lens's focus, the magnifying power ( M) is given by: M = 1 + D/f where D = 25cm (near point) and f = 5 cm. M = 1 + 25/5 = 6 Thus, the magnifying power is 6. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-Read more

M) is given by:
M = 1 + D/f
where D = 25cm (near point) and f = 5 cm.
M = 1 + 25/5 = 6
Thus, the magnifying power is 6.

Geo-tag your kitchen garden; include longitude and latitude coordinates.
To geo-tag your kitchen garden, use the GPS feature on your smartphone or a dedicated GPS device to determine the longitude and latitude. For instance, coordinates like 28.6139°N, 77.2090°E can help document its location. Apply geo-tags to garden photographs for better tracking and sharing. This ensRead more
To geo-tag your kitchen garden, use the GPS feature on your smartphone or a dedicated GPS device to determine the longitude and latitude. For instance, coordinates like 28.6139°N, 77.2090°E can help document its location. Apply geo-tags to garden photographs for better tracking and sharing. This ensures accurate identification of your garden’s position and aids in future references, allowing you to assess how local conditions affect plant growth.
See lessA solenoid with an iron core and a bulb are connected to a d.c. source. How does the brightness of the bulb change, when the iron core is removed from the solenoid?
When the iron core is removed, the solenoid's inductance decreases, reducing opposition to current changes. However, in a d.c. circuit, inductance has minimal effect in steady state. The current remains the same, so the brightness of the bulb does not change. For more visit here: https://www.tiwariaRead more

What did you do with the produce after harvesting from the kitchen garden?
After harvesting, the produce was washed thoroughly to remove any soil or residues. It was then sorted based on size and quality, ensuring only the best was used. The vegetables, such as brinjals and cucumbers, along with herbs like coriander, were incorporated into the school kitchen for preparingRead more
After harvesting, the produce was washed thoroughly to remove any soil or residues. It was then sorted based on size and quality, ensuring only the best was used. The vegetables, such as brinjals and cucumbers, along with herbs like coriander, were incorporated into the school kitchen for preparing fresh and nutritious meals. Any surplus produce was distributed among students and staff to encourage healthy eating habits and prevent wastage, fostering community involvement in the project.

As the object approaches the converging lens, the image moves away from the lens with increasing speed, remaining real, inverted, and diminished. When the object reaches the focus, the image forms at infinity. If the object stops at the focus, the image becomes highly magnified and theoretically forRead more
As the object approaches the converging lens, the image moves away from the lens with increasing speed, remaining real, inverted, and diminished. When the object reaches the focus, the image forms at infinity. If the object stops at the focus, the image becomes highly magnified and theoretically forms at an infinite distance.
