Answer:
Both are moving at 30 km/h, so their speed is the same. ... enough fuel for the trip/how long it will take. 4 Weight is a force, and so is a vector. ... c At 10 seconds David's displacement is.
Answer:
Distance covered by the sound in air is 800 meter and the time taken by the sound in water for the same distance is 0.5 seconds.
Explanation:
Given:
Speed of sound in air = 320 m/s
Speed of sound in water = 1600 m/s
Time taken to reach certain distance in air = 2.5 sec
a.
We have to find the distance traveled by sound in air.
Distance = Product of speed and time.
⇒
⇒
⇒ meters.
b.
Now we have to find how much time the sound will take to travel in water.
⇒ Time = Ratio of distance and speed
⇒
⇒ <em> ...distance = 800 m and speed = 1600 m/s</em>
⇒
⇒ seconds.
Distance covered by the sound in air is 800 meter and the time taken by the sound in water for the same distance is 0.5 seconds.
The force exerted between 2 point charges is directly proportional to the product of their strengths, is inversely proportional to the square of the distance between them and is inversely proportional to the absolute permittivity of the surrounding mediums.
I hope that helps somewhat, I'm only kind of sure that could be correct
In my opinion, it would be coke because of all the pressure
Visible light is incident perpendicularly on a grating with 340 rulings/mm. 679 is the longest wavelength that can be seen in the m = 4 diffraction.
Waves spreading outward around obstructions is known as diffraction. Sound, electromagnetic radiation like light, X-rays, and gamma rays, as well as very small moving particles like atoms, neutrons, and electrons that exhibit wavelike qualities all exhibit diffraction.
Diffraction's effects can frequently be observed in daily life. The most spectacular diffraction examples include light, such as when a CD or DVD's tightly spaced tracks create the well-known rainbow pattern when viewed from different angles. Waves bend around gaps and barriers due to diffraction.
