What is the length of a simple pendulum whose period is 1.00 s? about 0.249m. What is the length of simple pendulum whose time period is 2sec? Length, L = ? Hence, the length of a simple pendulum is 0.99 m or 1.0 m. What is the period of a pendulum whose length is 9.8 […]

Are humans the smartest animal? Despite the prevailing belief that humans dominate the animal kingdom when it comes to smarts, we’re actually ranked as the third-smartest species on the planet — at least according to Douglas Adams, author of “Hitchhiker’s Guide to the Galaxy.” But joking aside, there is something to be said for Douglas’ […]

How long does a passive RFID tag last? about 20 years What is inside a passive RFID tags? In PASSIVE RFID Tags we have generally two main components. One is ANTENNA COIL and another is MICROCHIP. As you can see in the above image, there is no BATTERY or any other ACTIVE POWER here. How […]

What happens to equilibrium when a strong acid is added? If hydrochloric acid was added to the equilibrium mixture, both hydrogen ions (H +) and chloride ions (Cl -) are being added. Hydrogen ions are on the right hand side of the equilibrium, therefore the equilibrium will shift to the left hand side to compensate, […]

Where does the sun go when it sets? Answer: The Sun, the Moon, the planets, and the stars all rise in the east and set in the west. And that’s because Earth spins — toward the east. Where does the moon rise if the Earth rotates counter clockwise? The Earth rotates counter-clockwise on its axis […]

Can a bulb added in a circuit with twisted wires light up? Answer. Answer: Yes,because it is still a complete circuit. What must be true for a circuit to light a bulb? Based on what you have seen, what must be true for a circuit to light a bulb? There has to be a lightbulb […]

Will we run out of rocket fuel? So no, it is literally impossible to run out of modern rocket fuel, as we basically reuse it (when burned, turned into water vapour, rains down, we collect it and separate it into the two gasses, which can then be burned again. We will only run out of […]

Will a microwave explode? The water in their body heats up due to molecular resonance with the microwaves. Their eyeballs may explode from the pressure build-up as the water in them turns to steam with nowhere to escape. After a few minutes the heat will have penetrated deep into their bodies, causing their internal organs […]
