How does a subordinating conjunction effect a sentence in German?
Let's take the word 'weil'. It means 'because' and is a subordinating conjunction. I remember the rhyme "the word weil, smells so vile, it makes the verb, run a mile" What I'm inferring is that it makes the verb go to the end of the sentence! That's what a subordinating conjunction such as weil or dass does. For example; Ich liebe Samstag, weil Ich keine Schule habe (I love saturday, beacause I have no school) The verb 'habe' gets sent to the end of the sentence because the subordinating conjunction 'weil' is used.
Given the following equation; 3a - 4 = a - 3 Solve the value of a.
We need to make a the subject by rearranging this equation to have a's on one side and numbers on the other. Let's begin by moving the 'a' on the right to the left side 2a - 4 = -3 What we did was take 'a' from both sides of the equation to keep them balanced. Now we can move the -4 over to the right side by adding 4 to both sides: 2a = 1 Now we get rid of the 'times by 2' by doing the opposite, that is to divide by 2 on both sides which cancels the 2 on the left leaving: a = 1/2 = 0.5
What are the assumptions made by Bohr in his model of the hydrogen atom?
1. The electron orbits the nucleus in a circular path under influence of the Coulomb attraction, 2. Only certain electron orbits are stable. These are orbits that hydrogen does not emit energy in the form of radiation. 3. Radiation is emitted by hydrogen when the electron 'jumps' from a more energetic initial state to a lower state. 4. The size of the allowed electron orbits is determined by the electron's orbital angular momentum
