Fluffy a greyhound travels 15 m in 2 seconds while another greyhound Tiberius travels 20 m is 3 seconds. Which dog is faster?
To determine which greyhound is faster, we can calculate their speeds. Fluffy travels 15 m in 2 seconds, giving a speed of 7.5 m/s (15 m ÷ 2 s). Tiberius travels 20 m in 3 seconds, resulting in a speed of approximately 6.67 m/s (20 m ÷ 3 s). Therefore, Fluffy is the faster greyhound.
One car travels 20 km hr faster than another While one of them travels 240 km the other travels 180 km Find the speed of the fast car?
Difference in distance covered = (240 - 180) = 60 kmBut since speeds differ by 20 kph, difference in distance is (20 x #hours).60 = 20 x #hours#hours = 60/20 = 3 hours.Fast car covers 240 in 3 hours ---> 80 kphSlow car covers 180 in 3 hours ---> 60 kph
If a child can run 10 meters while a car travels 30 meters how many meters can the child run while the care travels 66 meters?
22m, if we're talking ratios. but I'm not too sure
What travels at a constant speed while accelerating?
Anything that moves in a path that's not straight can do that.
If a horse runs 250 yards while a train travels 600 yards how many yards can the horse run while the train travels 3000 yards?
Well, isn't that a delightful question! If the horse runs 250 yards while the train travels 600 yards, we can see that for every 1 yard the train travels, the horse runs 0.4167 yards. So, if the train travels 3000 yards, the horse would run 1250 yards. Just imagine those happy little horses running freely alongside the train, creating a beautiful scene of movement and joy!
Which travels fastest sound air light or water?
Light travels the fastest among sound, air, light, and water. In dry air, sound travels around 343 meters per second, while light travels at approximately 299,792 kilometers per second, which is much faster. Water and air have slower speeds of sound compared to light.
Is mach 20 faster than light If not how much slower?
No, Mach 20 is not faster than the speed of light. The speed of light is approximately 299,792,458 meters per second in a vacuum, while Mach 20 is roughly 7.35 kilometers per second. Therefore, Mach 20 is significantly slower than the speed of light.
What does the light travel faster than the sound?
Light travels faster than sound because it does not require a medium to travel through, whereas sound does. Light travels through the vacuum of space at a speed of approximately 186,000 miles per second, while sound travels through air at a much slower speed of about 1,125 feet per second.
Why is it in a thunder storms you see the ligherning before the thunder?
Light travels faster than sound, so you see lightning before you hear the thunder. The lightning flash reaches your eyes almost instantly, while the sound of thunder takes longer to reach your ears because it travels at a slower speed.
Do x-rays travel slower than infrared?
No, x-rays travel faster than infrared radiation. X-rays have higher energy and shorter wavelengths, allowing them to travel at the speed of light in a vacuum while infrared radiation has longer wavelengths and travels at a slower speed.
Can you change your power while exercising?
Of course. You can run faster and slower. You can ride your bike faster or slower. You can ride it on a small slope or a steep slope. You can do more or fewer chin-ups or push-ups in each 10 seconds. You can lift lighter or heavier weights, and lift them faster or slower. You can run the treadmill faster or slower, and then keep up with it.
Which travels fastest through a medium a photon atom sound or electron?
A photon travels fastest through a medium, followed by sound, then electrons. Photons travel at the speed of light in a vacuum, which is faster than the speed of sound or electrons in a medium. Sound travels at a much slower speed than light, while electrons generally move at speeds that are significantly slower than both photons and sound waves.
How the speed of a wave of sound or light can be changed?
Many factors affect the speed of a wave of sound or light, but the easiest factor to change is the medium through which the wave travels. The speed of sound, 332 meters per second in dry air at sea level at 0oC, increases with temperature. It is much higher in liquids, about five times faster than in gases, and in metals it travels ten to fifteen times as fast as in air. It travels faster through gases less dense than air such as hydrogen and helium, but slower in heavier gases such as carbon dioxide. Sound does not travel through a vacuum because it relies on the vibration of atoms. It is also affected by humidity in air and the specific heat, density, and elasticity of any other medium through which it travels. The speed of light, about 300,000 kilometers per second in a vacuum, is less when it travels through any other medium. While it is very slightly slower in air, it travels at anywhere between 3/4 to less than1/2 as fast through liquids, glass and crystals, depending on the refractive index of the material.
What travels faster?
Light travels faster than sound. Light travels at a speed of about 186,000 miles per second (300,000 kilometers per second) in a vacuum, while sound travels at a speed of about 1,125 feet per second (343 meters per second) in air.
Is electricity faster than sound?
Yes. In air, sound travels at about 300 or 330 meters/second (it varies, depending on the temperature - also, sound in water or steel, for example, is quite a bit faster). But an electrical signal can go at about 2/3 the speed of light in a vacuum - that would be about 200,000 kilometers/second.
What travels faster light or sound?
Light travels at approximately 3x108m/s whilst sound travels only at 343m/s. So which do you think is the faster one?
Electromagnetic radiation and sound waves travel at the same speed?
No, electromagnetic radiation (such as light) travels faster than sound waves. In a vacuum, light travels at a speed of approximately 186,282 miles per second, while the speed of sound waves is much slower, around 767 miles per hour in air.
