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. […]

Why does light bend when it enters a different medium? The bending of light as it passes from one medium to another is called refraction. The angle and wavelength at which the light enters a substance and the density of that substance determine how much the light is refracted. The bending occurs because light travels […]

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, […]

What are two types of energy that can be released when something burns? When we burn Natural Gas, the chemical energy is converted into light and heat. Chemical energy is energy that is stored in the bonds between chemical compounds. It is released when a chemical reaction takes place. What types of energy does the […]

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 is selective breeding and why is it important? Selective breeding, also known as artificial selection, is a process used by humans to develop new organisms with desirable characteristics. Selective breeding can be used to produce tastier fruits and vegetables, crops with greater resistance to pests, and larger animals that can be used for meat. […]

Which has more thermal energy? If two objects made of the same substance have different masses or temperatures, you can determine which has more thermal energy. If the objects have different masses but are otherwise the same, the one with more mass has more thermal energy. What is thermal power in short? Thermal power describes […]

What is metal ductility? Material properties Ductility is the ability of a material to be drawn or plastically deformed without fracture. It is therefore an indication of how ‘soft’ or malleable the material is. The ductility of steels varies depending on the types and levels of alloying elements present. Is all metals are ductile? Answer […]

What are the two types of measuring instruments? Here are some most commonly used mechanical instruments for measurement in industries…. Vernier Caliper. Micrometer. Steel Scale. Vernier Height Gauge. Vernier Depth Gauge. Bevel Protractor. Dial Gauge (Plunger, Level) What is the instrument used for measuring weight? weight scales What instrument is used nowadays to weight things? […]

What is the dimensional formula for gas constant? Or, G = [M1 L-1 T-2] × [L3] × [K1]-1 = [M1 L2 T-2 K-1]. Therefore, the gas constant is dimensionally represented as [M1 L2 T-2 K-1]. What is the dimensional formula of Boltzmann constant? Or, k = [M1 L2 T-2] × [M0 L0 T0 K1]-1 = […]
