Question in NCL MAS1701
No description given

Question in CHY1201 - SpectroscopyThe reduced masses are pre-calculated for this question and included in a list. It would be more elegant to program Numbas to permute atoms together to generate diatomic molecules while constraining the permutations to those which are chemically/physically reasonable, so as to allow calculation of each reduced mass directly from the atomic masses- but organising this with high computational efficiency might be a significant programing task (add to "to do" list).

Merryn's copy of Division, single digit divisor results in no remainder - long or short division Ready to useQuestion in MESH
The simplest case. Divisor is single digit. There is no remainder.
-
Question in MESH
Divisor is single digit. There is a remainder which we express as a decimal by continuing the division process. No rounding is required by design (another question will include rounding off).
-
Question in MESH
Divisor is single digit. There is a remainder which we express as a decimal by continuing the division process. Rounding is required to one decimal place. The working suggests determining the second decimal place so the student knows whether to round up or down.
-
Question in MESH
Divisor is single digit. There is a remainder which we express as a fraction.
-
Question in MESH
Subtracting a decimal with 3 decimal places from a decimal with 2 or 3 decimal places. borrowing is necessary. This was modified from a subtraction question using integers with each number divided by 1000 so the variables have names referring to ones, tens, hundreds etc.
-
Question in MESH
a) Multiplying decimals with a single non-zero digit. Students are told to preserve the number of decimal places (from the question to the answer).
b) Multiplying decimals requiring the multiplication algorithm.
-
Question in How-tos
Shows how to use JSXGraph to make a sine graph with amplitude, frequency and phase controlled by sliders.
-
Question in Engineering Statics
Determine the moment of a force about a point by using $M= F d_\perp$ or $M = F_\perp d$.
-
