At the heart of quantum mechanics lies a radical shift in understanding: Matter and light, when examined at the microscopic level, behave both like particles and waves. Even more strangely, these particles exist in a superposition of all possible states until they are measured or observed. That’s like saying reality settles into a definite state only when you observe it. Sounds exotic

Air pressure is the force created by the weight of air in our atmosphere. It decreases as you go higher in altitude because there’s less air above you. At sea level, the atmosphere is denser, resulting in higher air pressure due to the weight of the air above.

This invisible force plays a vital role in shaping weather patterns—from influencing winds to forming clouds and driving storms. 🌧️

It’s measured using barometers and impacts everything from flight dynamics ✈️ to how comfortable we feel in different environments. 🌪️

Air pressure might be invisible, but its effects are everywhere! 💡
Have you ever experienced the impact of changing air pressure?

Electric bulb is marked 200 V , 100 W. Calculate electric resistance of its filament. If 5 such bulbs are connected in series to 200 V supply, how much current will flow through them?

To obtain maximum sensitivity and accuracy in a meter bridge, it is advised to obtain a null point at the middle of the wire.
In the middle of the wire ratio arms are nearly equal in resistance.
Wheatstone bridge is most sensitive when the resistance of its four-arm is of the same order. Since the Meter bridge works on the principle of Wheatstone bridge, balance point or null point is obtained at the middle of the Meter bridge wire.
The end resistance of the copper strips also produces the least effect
