Answer:
1. observations
2. hypothesis
3. experimentation
Explanation:
Observations are made, Hypothesies are formed from observations, and experimnets help alter and comfirm hypothesis.
As a rule, opposite charges attract. So,you would expect that the particle that would deflect towards the positive electrode has a negative charge. Now, an alpha particle is basically a neutral Helium atom. Beta particle is an electron. Gamma particle has no charge (neutral). <em>Thus, the answer is B.</em>
<u>Answer:</u> The energy of the complex is 
<u>Explanation:</u>
To calculate the energy of the complex, we use the equation given by Planck which is:

where,
= Wavelength of the complex =
(Conversion factor:
)
h = Planck's constant = 
c = speed of light = 
= Avogadro's number = 
= energy of the complex
Putting values in above equation, we get:

Conversion factor used: 1 kJ = 1000 J
Hence, the energy of the complex is 
The answers are the following that can be answered using the chart:
A. Which type of hurricane is expected to strike more frequently this century?
Category 4 + 5C. In general, will hurricanes likely become stronger or weaker this century?
Stronger, because there are more stronger ones thant he weaker ones that can result to hurricane.
E. Which types of hurricanes are expected to drop in frequency by more than 25% this century?
