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 […]
Do gamma rays travel faster than light?
Do gamma rays travel faster than light? Although the energy inherent to light is quantized into discrete energy packets (a.k.a., photons), there are some properties shared by all forms of light. Light of any wavelength, from picometer-wavelength gamma-rays to radio waves more than a trillion times longer, all move at the speed of light in […]

What forces act on a still object?
What forces act on a still object? Force is defined as a push or pull acting on an object. Forces include gravity, friction, and applied force. Force causes changes in the speed or direction of motion. These changes are called acceleration. What forces can change the shape of an object? When a force acts on […]
What 4 elements at room temperature can become permanently magnetized?
What 4 elements at room temperature can become permanently magnetized? There are only four elements in the world that are ferromagnetic at room temperature and can become permanently magnetized: iron, nickel, cobalt and gadolinium. (A fifth element, dysprosium, becomes ferromagnetic at low temperatures.) What happens when a watch is magnetized? Magnetization is a particular problem […]
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 […]
