The equation that we will use to solve these two questions is:
c = lambda * f where:
c is the speed f the wave
lambda is the wavelength of the wave
f is the frequency of the wave
Question 1:
we want to find f
c is assumed to be the speed of light = 3*10^8 m/sec
lambda = 5.6 * 10^10 cm = 560 * 10^6 meters
Substitute in the equation to get f as follows:
3*10^8 = 560*10^6*f
f = (3*10^8) / (560*10^6) = 0.5357 Hz
Question 2:
we want to find lambda
c is assumed to be the speed of light = 3*10^8 m/sec
f is given as 0.1096 Hz
Substitute in the equation to get lambda as follows:
3*10^8 = lambda * 0.1096
lambda = (3*10^8) / (0.1096) = 2.737226*10^9 meters
The answer is a. H+ and H2O. For a half-reaction in acidic solutions, elements that are not hydrogen and oxygen are balanced first. Then we add H2O to balance oxygen atoms and we add H+ to balance the hydrogen atoms. We do the same steps for basic solutions, but we also add hydroxide ions OH- in the latter part.
Hey im happy to help!
Heat can float from one place to another, like all energy.Heat floats in solids by conduction, that happens because the molecules hit one another.Heat within the solid will flow from hot to cold.Heat will flow downward if its cold there.
Hope this helps, have a great rest of your day!
Answer:
The false statement from the given statements is option a.
Explanation:
Hypothesis:
A hypothesis is a intelligent guess or prediction to interpret or explain any phenomena.
It is tested through the series of experiments and by number of studies to actually decide whether hypothesis is in agreement with observation and results predicted by it. These prediction are made on basis of limited evidences. It can be false or true.
Theory:
A theory is an in depth explanation behind any physical phenomena which has been tested multiple times through the correct scientific methods and experimentation. It will give same results and observations.
