What is the effect of the Gulf Stream of Europe? Since the Gulf Stream also extends toward Europe, it warms western European countries as well. In fact, England is about the same distance from the equator as cold regions of Canada, yet England enjoys a much warmer climate. If it weren’t for the warm water […]
What is the Doppler effect and why is it important?
What is the Doppler effect and why is it important? The Doppler effect is important in astronomy because it enables the velocity of light-emitting objects in space, such as stars or galaxies, to be worked out. What are two everyday applications of the Doppler effect? The Doppler effect has several real-world applications. For example, besides […]
Is gravitational force equal to weight?
Is gravitational force equal to weight? The gravitational force on Earth is equal to the force the Earth exerts on you. At rest, on or near the surface of the Earth, the gravitational force equals your weight. What two factors does gravitational force depend on? When dealing with the force of gravity between two objects, […]
What are the different parts of the eye?
Is VX and VY constant?
Is VX and VY constant? Here are some formulas that describe projectile motion: Thus the vertical velocity (Vy) is continually increasing. The horizontal velocity (Vx) remains constant and is equal to Vxo. If an object is pointed at an angle, the motion is essentially the same except that there is now an initial vertical velocity […]
Can you capture an image formed by a convex mirror on a screen?
Can you capture an image formed by a convex mirror on a screen? Why it is not possible to capture an image formed by convex mirror ? A convex mirror, also known as a diverging mirror, as this mirror diverges light when they strike its reflecting surface. It always forms virtual, erect, and diminished images […]
What kind of image is formed with a pinhole camera?
What is the formula for volume of pyramids?
How does high voltage reduce power loss?
How does high voltage reduce power loss? High voltage transmission minimizes the amount of power lost as electricity flows from one location to the next. The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. And when resistance losses are low, energy losses are low […]
