What are two signs of hydroplaning? It’s sometimes hard to tell when you’re hydroplaning. The vehicle’s rear end may be a little squirrelly. Steering may feel loose or too easy. Watch for standing water or spray from vehicles in front of you. Should I buy AWD or FWD? It’s lighter, so front-wheel drive cars tend […]
What is the relationship between angular speed frequency and period?
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?
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 heat loss by radiation?
What is heat loss by radiation? Radiation is a form of heat loss through infrared rays. This involves the transfer of heat from one object to another, with no physical contact involved. For example, the sun transfers heat to the earth through radiation. The last process of heat loss is evaporation. How can a patient […]
What are the major components of a projectile motion?
What are the major components of a projectile motion? There are the two components of the projectile’s motion – horizontal and vertical motion. And since perpendicular components of motion are independent of each other, these two components of motion can (and must) be discussed separately. What is the vertical component of the velocity just before […]
What would happen if the orbit was circular?
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 […]
How do you represent elevation?
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 […]
What is period of the wave?
Which correlation is the weakest?
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 ± […]
