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 […]

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? The formula involves dividing 360 by the number of sides to calculate the corner angle. Then divide it by two to get the miter angle. If you’re making a five-sided project with all sides equal, you divide 360 by five to get 72 degrees. So each joint […]

What is D-block in jail? D-Block housed the worst inmates and five cells at the end of it were designated as “The Hole”, where badly behaving prisoners would be sent for periods of punishment, often brutally so. How do I learn d-block elements? D-block elements it includes are Lutetium (Lu), Hafnium (Hf), Tantalum (Ta), Tungsten […]

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 […]
