What would happen if the orbit was circular? “If the Earth’s orbit were a perfect circle, we would not have seasons.” This statement is clearly false. A perfectly circular orbit would mean that the earth is always the same distance from the sun. However, the primary cause of our seasons is the tilt of the […]

What is the relationship between angular speed frequency and period? Period, , is defined as the amount of time it takes to go around once – the time to cover an angle of radians. Frequency, , is defined as the rate of rotation, or the number of rotations in some unit of time. Angular frequency, […]

What are the disadvantages of using a pinhole camera? The image formed does not give any details. Usually, it is faint. Image is obtained on the screen and no permanent record of the image can be obtained. Pinhole camera cannot be used for studying moving objects. What are the major differences between a pinhole camera […]

What is period of the wave? The period of a wave is the time for a particle on a medium to make one complete vibrational cycle. Period, being a time, is measured in units of time such as seconds, hours, days or years. The period of orbit for the Earth around the Sun is approximately […]

Which correlation is the weakest? Strength – The weakest linear relationship is indicated by a correlation coefficient equal to 0 (actually this represents no correlation!). The strongest linear correlation is indicated by a correlation of -1 or 1. What is considered a low correlation? Moderate degree: If the value lies between ± 0.30 and ± […]

How do you get hide in Family Island? For example, to get animal hide, you will have to feed a goat. To do this, make goat feed at the mill. To prepare feed, you will need roots and grass – Gather tufts of grass from the island and grow/harvest roots in garden bed. How do […]

How do you represent elevation? Elevation is distance above sea level. Elevations are usually measured in meters or feet. They can be shown on maps by contour lines, which connect points with the same elevation; by bands of color; or by numbers giving the exact elevations of particular points on the Earths surface. How do […]

Is the vitreous attached to the retina? The vitreous is the gel-like fluid that fills your eye. It’s full of tiny fibers that attach to your retina (the light-sensitive layer of tissue at the back of the eye). What is the function of vitreous Humour in eye? Along with maintaining the shape of the eye, […]

What are limitations in engineering? A term used to determine a minimum and maximum. In a mechanism, it should denote the minimum and maximum sizes for each part, between which the parts will function properly in conjunction with each other an outside of which they will not. What are material limitations? No Order or Law […]

Is it rude to say here you go? “Here you go” and “There you go” are quite informal. If you say this to your teacher or your boss, they might think you’re being rude or impolite. So use the more formal “Here you are” or “There you are” instead. How do you say no comprende? […]
