Each successive graph is at a later time. You can see from these graphs how the amplitude of the total electric field changes, but the positions of the crests and troughs (called antinodes) and places of zero field (called nodes) never change.!!!!!!!!!!!!!!!!!
The correct answer is that water, as it rises in the atmosphere, condenses and forms clouds - the correct answer is b.
Other options are false, for example:
a. It evaporates.
-this is the beginning of the process: water needs to evaporate to be in the atmosphere - so it's before the process that the question addresses
Also it is not used up: otherwise Earth would run out of water.
Answer:
A.88 feet per second.
B.96.56 km /hr
Explanation:
A
When converting from miles per hour to feet per second, we can use the following conversion factor.
1 mile per hour = 1.46667 feet per second.
Hence, 60 miles per hour will be = 60 X 1.46667 = 88 feet per second.
B.
Similarly, we can use the same process when converting from miles per hour to km per second.
1 mile = 1.60934 km
hence to convert we will multiply 60 miles/hour by 1.60934 km = 96.56 km /hr
Answer:
E = h f = h c / λ energy of single photon
n E = 4.00E-11 W/m^2 energy required for visibility
n h c / λ = 4.00E-11 number of photons required for visibility (per square meter)
n = 4.00E-11 * 5.00E-7 / (6.63E-34 * 3.00E8)
n = 20.0E-18 / 19.9 E-26 = 1.00E8
100 million photons would be required on 1 m^2 to create visibility
a / A = π * (3.6E-3)^2 / 1 = 4.07E-5 fraction of area available
4.07E-5 * 1.00E8 = 4.07E3 photons required
I’d think the answer would be C. i’m just kinda guessing but my thought process is this (as simply as i can put it because physics is confusing):
so for example say you throw a ball across a flat surface. inertia is what keeps the ball rolling straight in a line, so unless you were to maybe put your hand in front of the ball or something, it would just go straight forever.
this is what happens with the planets. they go in a straight line, but since there’s gravity, the planets are also being pulled towards the sun. so gravity and inertia are why the planets orbit in the circle pattern they do. so when we remove inertia, we’re removing the state in which the planets keep going straight while being pulled towards a center point (the sun). this causes gravity to be the only factor in the planets orbiting. so that being said, the planets would just be pulled towards the sun. :)
