Infrared light has longer wavelengths than gamma rays, X-rays, ultraviolet light, and visible light, but shorter wavelengths than microwaves, radar, GPS, cellphone, TV, radio, ocean, audible sound, ultrasound, seismic, guitar-string, and Slinky™ waves.
This is conservation of momentum. At the beginning the total momentum is zero. When you throw the stone you give the stone a positive momentum, which means you must have a negative momentum (when I say negative I mean in the opposite direction of the direction of the stone) so that the total momentum is still zero. You and the canoe will move in the opposite direction of which you threw the stone.
For any periodic wave
<span>v = f λ </span>
<span>where </span>
<span>v = velocity </span>
<span>f = frequency </span>
<span>λ = wavelength (distance between 2 successive crests) </span>
<span>This means that </span>
<span>λ = v/f </span>
<span>Assuming that v stays the same while f increases, λ must DECREASE.
I hope this helps

UHHHHHH yes...... well depends on what the question is asking but more times then not yes they matter.
Answer:
<em>3.5 A</em>
Explanation:
Current [A] =Electrical power [W] ÷ Potential difference [V]
KW TO W = ×1000
hence,
800W÷230V= 3.5A (1 d.p)
