Do you get pulled over if caught by a speed gun? Radar and laser guns Used by roadside police officers, hand-held speed guns are pointed at oncoming cars and they are able to give an instant speed reading. If you’ve exceeded the speed limit, you’re likely to be pulled over. Does a cop have to […]
How far can you kick a ball?
How far can you kick a ball? While some weaker placekickers may have trouble kicking field goals longer than 30 yards (making field goals from beyond the 13 difficult), others may consistently make 50-yarders, making it practical to kick from beyond the 33. For most NFL kickers, the 35-yard line is typically the limit of […]
What are the stages of reflection?
What are the stages of reflection? Stages. The traditional stages of reflection are self-awareness, description, critical analysis, synthesis, and evaluation. This is the cognitive model of learning by reflection. What are the reflective models? One of the most famous cyclical models of reflection leading you through six stages exploring an experience: description, feelings, evaluation, analysis, […]
How are the wavelength and frequency related?
How are the wavelength and frequency related? What is the relationship between frequency and wavelength? The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength. What is the […]
Do we see with our eyes or brain?
Do we see with our eyes or brain? Our eyes do a really good job of capturing light from objects around us and transforming that into information used by our brains, but our eyes don’t actually “see” anything. That part is done by our visual cortex. Our eyes being slightly apart creates an image that […]
How do you find maximum velocity?
How do you find maximum velocity? Using Calculus If acceleration is positive to the left and negative to the right, the point is a maximum velocity. In the example, a=3cos(t) is positive just before t=π /2 and negative just after, so it is a maximum; however, 3π/2 is a minimum because a=3cos(t) is negative just […]
How long does it take a star to return to the same position in the sky as it was the night before?
What is centripetal acceleration in simple words?
What is centripetal acceleration in simple words? Centripetal acceleration is defined as the property of the motion of an object, traversing a circular path. Any object that is moving in a circle and has an acceleration vector pointed towards the center of that circle is known as Centripetal acceleration. What is the formula of uniform […]
What are the 4 components of a galaxy?
Which one has a higher electrical resistance a 100 watt bulb or a 60 watt bulb?
Which one has a higher electrical resistance a 100 watt bulb or a 60 watt bulb? A 60-watt bulb has a higher electrical resistance than a 100-watt bulb. Because power is inversely proportional to resistance, when the power is less, the resistance is high. Which one is having lesser resistance a 220v 60W bulb or […]
