What is the volume of a block of wood that is 3 cm on each side? The block of wood is 3cm on each side so it is a cube. The volume of a cube is given by s^3. So the volume of this block is 3cm x 3cm x3 cm = 27 cm^3. What […]
Can we prove axioms?
Can we prove axioms? Unfortunately you can’t prove something using nothing. You need at least a few building blocks to start with, and these are called Axioms. Mathematicians assume that axioms are true without being able to prove them. If there are too few axioms, you can prove very little and mathematics would not be […]
How do you describe a distance time graph?
How do you describe a distance time graph? If an object moves along a straight line, the distance travelled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the […]
What happens to the force of attraction when?
What happens to the force of attraction when? Hence force of attraction will be quadrupled. (1) When distance between objects is doubled, force of attraction will become 122=14 times i.e. will become one-fourth. (3) When distance between objects is halved, force of attraction will become 1(12)2=114=4 times i.e. will become four times. How many G’s […]

What are the advantages of interdisciplinary studies?
What are the advantages of interdisciplinary studies? Interdisciplinary programs draw from two or more academic disciplines that work together to create a powerful learning experience and emphasize integrative learning, critical thinking, and creative problem solving. What is the main aim of interdisciplinary research? 20) What is the main aim of interdisciplinary research? Explanation: Particularly in […]
What is unusable energy called?
What is unusable energy called? In every energy transfer, some amount of energy is lost in a form that is unusable. In most cases, this form is heat energy. Thermodynamically, heat energy is defined as the energy transferred from one system to another that is not doing work. Entropy is a measure of randomness or […]
What is grashof condition?
What is grashof condition? The Grashof condition for a four-bar linkage states: If the sum of the shortest and longest link of a planar quadrilateral linkage is less than or equal to the sum of the remaining two links, then the shortest link can rotate fully with respect to a neighboring link. What is K […]
What are the 4 ways to manage risk?
What are the 4 ways to manage risk? Once risks have been identified and assessed, all techniques to manage the risk fall into one or more of these four major categories: Avoidance (eliminate, withdraw from or not become involved) Reduction (optimize – mitigate) Sharing (transfer – outsource or insure) Retention (accept and budget) What is […]
