What are two customary units of length? The customary units to measure length and distances in the customary system are inches, feet, yards, and miles. What are units in words? A unit is a single, whole part of something, like a building block. The word unit started out in math but has branched out to […]
How is short circuit protected?
How is short circuit protected? A short-circuit condition means a circuit allows the current to flow through an unintended path with very low electrical impedance. It is a direct contact between two points of different electric potential. How do you know what size fuse to use? The fuse rating should lie somewhere between these two […]
What are the two factors which help in determining the state of matter?
What are the two factors which help in determining the state of matter? Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. Kinetic energy tends to keep the particles moving apart. How do you tell […]
What are 3 characteristics of the mantle?
What are 3 characteristics of the mantle? It is mostly solid rock, but less viscous at tectonic plate boundaries and mantle plumes. Mantle rocks there are soft and able to move plastically (over the course of millions of years) at great depth and pressure. The transfer of heat and material in the mantle helps determine […]
Why is pressure not proportional to volume if the temperature changes?
Why is pressure not proportional to volume if the temperature changes? Remember that the force of the collisions do not change unless the temperature changes. If the temperature of a gas stays the same, the pressure of the gas increases as the volume of its container decreases. What happens to volume if temperature increases? The […]
What are three examples of compound machines?
What are three examples of compound machines? A compound machine consists of two or more simple machines. Examples of compound machines include bicycles, cars, scissors, and fishing rods with reels. Compound machines generally have lower efficiency but greater mechanical advantage than simple machines. Is a wheelbarrow a mechanism? Wheelbarrows are compound machines. It consists of […]
What is the 7 electromagnetic waves?
What is the 7 electromagnetic waves? The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays. Which color has the most energy and why? Violet What is meant by […]
What parts of the foot should you use while kicking the ball?
What are the types of scrutiny?

The Supreme Court has found the following situations to correspond to these levels of scrutiny. What falls under strict scrutiny? To pass strict scrutiny, the legislature must have passed the law to […]
How thick should you lay River Rock?
How thick should you lay River Rock? The suggested depth of coverage varies according to the size of the individual stones. If the stone size is 1/2-inch or less, the suggested depth is 2-inches. Stones that are 3/4-inch to 1-inch should have a depth of about 3-inches. Stones that are 1-inch or larger should have […]
