How do you know if its BCC or FCC? If the unit cell also contains an identical component in the center of the cube, then it is body-centered cubic (bcc) (part (b) in Figure 12.5). If there are components in the center of each face in addition to those at the corners of the cube, […]

What is a secondary crop? 1 : a second harvest from the regrowth or second growth of a crop (as broomcorn) after harvesting earlier in the season. 2 : a crop planted after harvesting another crop on the same land earlier in the season. Which of the following is a benefit of crop rotation? A […]

Is boron a metal or metalloid? Boron is a non metallic element and the only non-metal of the group 13 of the periodic table the elements. Boron is electron-deficient, possessing a vacant p-orbital. Why is boron not a metalloid? Boron is neither a metal nor a non-metal; it is kept in the category of metalloids. […]

Why whales are called filter feeders? Whales called as filter feeders because they used to filtered their food through baleen plates. they suction water into their mouths at high velocities while their body remains stationary. The food along with water moves through the filtering pads or baleen plates that covered the entrance of their throat. […]

Can you go to jail for cheating on Act? Yes, if you helped someone else cheat, you certainly could do jail time (probably not much, but still, any jail time is too much in my humble opinion) for criminal fraud, and possibly sued for fraud by the College Board, the schools to which you applied, […]

Why it is easy to pull than push? Friction is the force acting between the object and the surface. So, when there will be less force of friction, it is easier in that case to move the body. Hence, it is easier to pull than to push a body. What is easier push or pull […]

Does the ball lose the same percentage of energy with each bounce or is there an increase or decrease? We have the kinetic energy of the ball and the potential energy due to gravity. At the top of the bounce, there is no kinetic energy so all the energy is potential. For example, if a […]

What is the principle of a screw? A screw is a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force. It is one of the six classical simple machines. The most common form consists of a cylindrical shaft with helical grooves or ridges called threads around the […]

What three things do we unconsciously automatically process? We unconsciously and automatically encode incidental information, such as space, time, and frequency. We also register well-learned information, such as words in our native language, by this form of processing. Which memory process generally requires attention? What are the two main parts of the memory process? There […]
