Why are gamma rays not affected by a magnet as they pass over it?
Assoli18 [71]
Gamma is not affected by both fields because it isnt charged. 

Only alpha and beta ray will be affected because they are charged with positive and negative ions respectively.

In otherwords, <span>Gamma rays are high-energy photons of light, which have zero electric charge. So they are not affected by magnetic fields</span>

Here's a chart. .

If that doesnt help tell me :)

An experiment is designed to determine if the amount of sugar in a drink affects the likelihood that bees will be attracted to i
guajiro [1.7K]

Answer:

The amount of sugar in the sample

Explanation:

The independent variable is not dependent on the other observed variable in an experiment. So In this case, it is the amount of sugar as it does not change by the other variable in the experiment, i.e. the number of bees that visit the sample.

The other options are irrelevant in this experiment because they are not being studied.

What is the ph of with a 4.6 x 10-6 M hydroxide ion concentration?
Lunna [17]
<h3>Answer:</h3>

pH = 8.66

<h3>Explanation:</h3>
  • The pH refers to the acidity or alkalinity of a solution.
  • It is calculated by getting the negative logarithm of Hydrogen ions concentration.
  • pH=-log[H⁺]

In this case;

we are given [OH⁻] as 4.6 x 10^-6 M

We are required to calculate the pH

We need to know that;

pH + pOH = 14

pOH = -log[OH⁻]

To get the pH we can calculate the pOH first,

pOH = -log[4.6 x 10^-6 M]

        = 5.34

but, pH + pOH = 14

Therefore, pH = 14 - pOH

                        = 14 - 5.34

                        = 8.66

Therefore, the pH of the solution is 8.66
