What are the types of elevation? Elevations depict how your home will look when viewed from specific angles. There are different types of elevation with respect to these specific angles. Front elevation, side elevations, rear elevations and split elevations are some types. What does an elevation drawing show? An elevation drawing is an orthographic projection […]

Do you drill wood fast or slow? Tip 3: choose the right RPM If you drill too fast, chances are your wood might burn. If you drill too slow, the drill hole might not turn out as nice. Should I lubricate drill bit? Lubricating the bit reduces friction and heat buildup, which makes drilling easier […]

Why do sea breezes occur in the day but not at night? Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the […]

What do you do when a student refuses to participate? If a student is outwardly refusing to do work in the classroom, there is always a reason….If they are in the classroom, keep teaching them! Give wait time. When a student refuses work at first, sometimes all they need is a little wait time. Ignore […]

What is relation and function example? For example, y = x + 3 and y = x2 – 1 are functions because every x-value produces a different y-value. A relation is any set of ordered-pair numbers. In other words, we can define a relation as a bunch of ordered pairs. How can you tell if […]

What are the two uses of electricity?

How many watts of radiation is dangerous? To cause death within hours of exposure to radiation, the dose needs to be very high, 10Gy or higher, while 4-5Gy will kill within 60 days, and less than 1.5-2Gy will not be lethal in the short term. However all doses, no matter how small, carry a finite […]

Why is a frame of reference needed? A frame of reference is a set of coordinates that can be used to determine positions and velocities of objects in that frame; different frames of reference move relative to one another. This means that we can address problems in any reference frame to give an equivalent solution. […]

Why is the surface of Mercury often compared with that of the Moon list two similarities? Mercury is often compared to the moon because its surface looks similar to the backside of the moon (the main source of erosion for both is meteorite impact). Both have weak magnetic fields, but mercury doesn’t have any Maria […]

What are the evidences of physical and chemical changes? Common physical changes include melting, change of size, volume, color, density, and crystal form. The classic baking soda and vinegar reaction provides evidence of a chemical change due to the formation of a gas and a temperature change. Is a change in texture physical or chemical? […]
