Can a body have zero velocity and still be accelerating? Yes, an object can have zero velocity and still be accelerating simultaneously. Then the object will start to move in the backward direction. Is acceleration zero at the turn around point? 4. Acceleration is always smaller then velocity. A point where an object reverses its […]

What is natural frequency and resonance? The natural frequency is the frequency at which an object will remain vibrating after hitting it. What happens when you excite that object at the same frequency as its natural frequency? Well, that is resonance. What is the difference between frequency and fundamental frequency? The fundamental frequency is just […]

What to do if you hear scratching in your walls? If you hear scratching in your walls but have yet to actually see pests or rodents, your best bet is to call a pest control company and have a professional come out to assess the situation. Remember, a pest that might seem harmless, like a […]

They are: the New Moon; Waxng Crescent; First Quarter (or half-full; Waxing Gibbous; Full Moon; Waning Gibbous; Last Quarter (half-full on other side); Waning […]

What happens during refraction? Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. The wavelength decreases as the light enters the medium and the light wave changes […]

What is the ocular lens used for on a microscope? Ocular Lens – The ocular lens, or eyepiece, magnifies the image. It contains a measuring scale called and ocular micrometer. The ocular micrometer has no units. Revolving Nose Piece – Several objective lenses of varying magnification and numerical aperture are mounted on the revolving nosepiece. […]

What is the slope of the line with vector equation? Clearly the answer is that the slope is the dot product of the two vectors: slope = g · u. There are two ways to think of the slope of a linear function in a given direction. We can use a symbol, such as s, […]

Is bamboo a forest product? The Union Ministry of Environment and Forests has asked states to treat bamboo as a minor forest produce (MFP). They insist that since the Indian Forest Act 1927 treats bamboo as a tree, it cannot be treated as an MFP (see ‘Is bamboo a tree or a grass’, Down to […]

Can a graph have 2 y axis? When the data values in a chart vary widely from data series to data series, or when you have mixed types of data (for example, currency and percentages), you can plot one or more data series on a secondary vertical (Y) axis. Can you have two Y axis […]

What are the disadvantages of drinking more water? Here are some disadvantages of drinking too much water: 1. It is said that too much consumption of water can lead to fluid overload in the body and imbalance in the body. Excess water can lead to lower sodium levels in the body, which may further lead […]
