Experimental limitations: Why is it far easier to measure e/m experimentally than either e or m individually? Note: "the numbers involved are small" is not a complete answer; while that has elements of the truth, there's a deeper reason that you should get at.
Homework Answers
The acceleration of electron in a potential V can be written as,
a = (e/m) V
Where V is the electric potential.
Acceleration of electron is easy to measure since it involves
measuring the deflection of electrons on a fluorescent screen.
It is easy to measure e/m ratio since it comes directly in a quantity that we can measure comfortably. On the contrary, neither charge e or mass m does not appear individually. This is the reason why the charge of the electron was measured much later (1911) than the e/m ratio (1897).

Based on the article "Proxy War," create your own argument that either supports or counters the author's argument (you either agree with the author's conclusion [support his argument] or you disagree with the author's conclusion [counter his argument]). Be sure you are not just developing your argument with the opinion that you already have. This means you must first recognize your initial point of view and your own assumptions about the topic, so you can approach it with an open...

You will be writing a simple Java program that implements an ancient form of encryption known as a substitution cipher or a Caesar cipher (after Julius Caesar, who reportedly used it to send messages to his armies) or a shift cipher. In a Caesar cipher, the letters in a message are replaced by the letters of a "shifted" alphabet. So for example if we had a shift of 3 we might have the following replacements: Original alphabet: A B C...

No economic disaster, but we are stuck in low gear Prime Minister Scott Morrison's claim that this week's soft economic growth figures were "no surprise" is itself a bit, well, surprising. If the government had such a strong inkling the Australian economy would endure a weak June quarter, why did it only really start softening up the public this week, in the days leading up to the national accounts? Why didn't the April budget build more of this anticipated softness...
