Answer:
Many substances do not dissolve in water and that is because they are non-polar and do not interact well with water molecules. A common example is oil and water. Oil contains molecules that are non-polar, thus they do not dissolve in water.
Explanation:
<span>Very wild guess at this one, since I've no idea what "standard wave format" means. First gap would be TRANSVERSE. Second gap could be LONGITUDINAL, or SOUND. Third gap could be ELECTROMAGNETIC (the two possible waves being the ELECTRIC wave and the MAGNETIC wave). http://perendis.webs.com</span>
Answer:
Janet jumps off a high diving platform with a horizontal velocity of 2.89 m per s and lands in the water 1.5 s later. How high is the platform?
Platform is 11.025 meters high .
Explanation:
we have Vx = 2.89 m/s
time taken = 1.5 seconds
height of the platform = ?
so,
As Janet is jumping from a high diving platform from a certain unknown height their must be involvement of gravity in action.
we can use,
h = Vi*t+(1/2)*g*t^2
where ,
h = height
Vi = initial horizontal velocity that will be zero
t = time in seconds
g = gravity due to acceleration
now put the values
h = 0+(1/2)*(9.8)*(1.5)^2
h = 11.025-m
Answer: radiant energy
Explanation:
The energy in electromagnetic waves is sometimes called radiant energy.
