What is the direction of a vector? The direction of a vector is the measure of the angle it makes with a horizontal line . One of the following formulas can be used to find the direction of a vector: tanθ=yx , where x is the horizontal change and y is the vertical change. What […]
What is molecular mass also known as?
What is molecular mass also known as? Molecular mass is also called molecular weight. Because the mass is relative to carbon-12, it’s more correct to call the value “relative molecular mass”. A related term is molar mass, which is the mass of 1 mol of a sample. Molar mass is given in units of grams. […]
Does standing next to a microwave cause cancer?
Does standing next to a microwave cause cancer? Microwaves are therefore not known to damage DNA inside cells, according to the American Cancer Society. As a result, there is “little cause for concern” about excess microwaves leaking out from your oven, unless there is damage to the door hinge, latch or seal, the FDA says. […]
How does light interact with eyes?
How does light interact with eyes? Light rays enter the eye through the cornea, the clear front “window” of the eye. The cornea’s refractive power bends the light rays in such a way that they pass freely through the pupil the opening in the center of the iris through which light enters the eye. The […]

What is the mechanical advantage of a simple block and tackle with one rope? The mechanical advantage is 2, requiring a force of only 50 N to lift the load. How do you calculate the mechanical advantage of a mousetrap car? The total mechanical advantage can be calculated by multiplying the two: 1/6 x 1/19 […]

What is transmitted when white light passes through a green filter?
What is transmitted when white light passes through a green filter? The filter selectively transmits the red and blue portions of the incident white light spectrum, but absorbs most of the green wavelengths. As discussed in our section on primary colors, the color magenta is obtained by subtracting green from white light. What does a […]
How can I make my body transparent?
How can I make my body transparent? While tissue clearing has been used for decades to see through tissues, the new approach used by Dr Ertürk and his colleagues also makes it possible to make bones transparent too. It builds on a technique known as 3D Imaging of Sovent-Cleared Organs, or 3DISCO. What body parts […]
