Why do shoots grow up and roots grow down? Roots respond to gravity and shoots grow towards sunlight. Roots – Roots grow down because the root respond to gravity by releasing the chemicals that prevent growth on the lower side,thus turning the root downwards. Why do shoots grow away from gravity? The roots grown downward […]

What is definition of inertia? Inertia, property of a body by virtue of which it opposes any agency that attempts to put it in motion or, if it is moving, to change the magnitude or direction of its velocity. Inertia is a passive property and does not enable a body to do anything except oppose […]

Does cold weather affect radio signals? In conclusion, both temperature and humidity have an effect on the transmission of radio waves. Conclusion 1: The temperature is inversely proportional to the strength of radio waves, Conclusion 2: The relative humidity in the air is inversely proportional to the strength of radio waves. What is a safe […]

How do you calculate Joule-Thomson effect? The Joule-Thomson equation is μ = (T1 – T2) / (P1 – P2) where μ is the Joule-Thomson coefficient, T1 is the initial temperature, T2 is the final temperature, P1 is the initial pressure and P2 is the final pressure. How is the Joule-Thomson coefficient derived? Here we are […]

What are the types of elevation? Elevations depict how your home will look when viewed from specific angles. There are different types of elevation with respect to these specific angles. Front elevation, side elevations, rear elevations and split elevations are some types. What does an elevation drawing show? An elevation drawing is an orthographic projection […]

Do you drill wood fast or slow? Tip 3: choose the right RPM If you drill too fast, chances are your wood might burn. If you drill too slow, the drill hole might not turn out as nice. Should I lubricate drill bit? Lubricating the bit reduces friction and heat buildup, which makes drilling easier […]

Do noise Cancelling headphones block all sound? Active noise-canceling headphones can do everything that passive ones can do — their very structure creates a barrier that blocks high-frequency sound waves. They also add an extra level of noise reduction by actively erasing lower-frequency sound waves. Is Noise Cancelling bad for ears? So, Is Noise-Canceling Safe? […]

What is relation and function example? For example, y = x + 3 and y = x2 – 1 are functions because every x-value produces a different y-value. A relation is any set of ordered-pair numbers. In other words, we can define a relation as a bunch of ordered pairs. How can you tell if […]

What is the quantity of heat required to raise the temperature of 1 gram of water through 1 C is called? The calorie was originally defined as the amount of heat required at a pressure of 1 standard atmosphere to raise the temperature of 1 gram of water 1° Celsius. Since 1925 this calorie has […]
