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 […]
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 […]
Do longer wavelengths have low energy?
Do longer wavelengths have low energy? Related to the energy and frequency is the wavelength, or the distance between corresponding points on subsequent waves. Shorter waves move faster and have more energy, and longer waves travel more slowly and have less energy. Why do short waves have high energy? “Short wavelength” is the same as […]
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 […]
Why is transpiration an important process in a plant?
Why is transpiration an important process in a plant? It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis. Plants need to cool themselves for several reasons. Transpiration is an evaporative cooling system that brings down the temperature of plants, but since it leads to water loss, […]
How do you know what angle to cut?
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 are the three types of buoyancy?
What are the three types of buoyancy? What are the three types of buoyancy? The three types of buoyancy are positive buoyancy, negative buoyancy, and neutral buoyancy. Positive buoyancy is when the immersed object is lighter than the fluid displaced and this is the reason why the object floats. How do you pronounce Euclid’s? Wiki […]
Why do some object float and others sink?
Why do some object float and others sink? Why do some things float and other things sink? It depends on the density of the object. Density is a measure of both how massive those molecules are, and how closely packed together they are. If the object’s total density is greater than that of water, it […]
