What is an example of contraction? A contraction is a word made by shortening and combining two words. Words like can’t (can + not), don’t (do + not), and I’ve (I + have) are all contractions. They’re so common that movies and books often try to make characters seem old-fashioned or strange by having them […]

How do I know if my refrigerator condenser is bad? Although a broken compressor is just one common problem with refrigerators, it can also be one of the most often overlooked, too. Your compressor kicking on and off is what you hear (or don’t hear) at various points during the day – you hear a […]

How does a person move forward during swimming? A person applies force on the water in backward direction and water according to the third law of motion water apply an equal and opposite force in the forward direction which helps a person to swim. How do swimmers reduce drag? Here are ten good ways to […]

What does it mean when an object does not slip? It means the object moves uniformly in one direction along the surface, with no angular velocity about the object’s own center of mass. What does it mean when a ball rolls without slipping? Rolling without slipping is a combination of translation and rotation where the […]

How do you calculate the no load speed of a DC motor? By multiplying the velocity constant by the nominal motor voltage, obtain the theoretical no-load speed of the motor (zero torque and no-load speed) and plot it on the left vertical axis. Draw a straight line between this point and the stall torque and […]

What do the arrows in a food chain represent quizlet? Food chains show which organisms eat other organisms. The arrows represent the direction of the transfer of energy from one organisms to the next. What causes the arrows to move in this direction? The earth’s rotation causes a phenomenon called Coriolis effect. The lower latitudes […]

Why is current constant in a parallel circuit? Each resistor in parallel has the same voltage of the source applied to it (voltage is constant in a parallel circuit). Parallel resistors do not each get the total current; they divide it (current is dependent on the value of each resistor and the number of total […]

What is considered a significant financial interest SFI that must be reported? A “Significant Financial Interest” (SFI) is the receipt by you, your spouse, or your dependent children of any of the following, if related to your University responsibilities or professional expertise: Income that exceeds $5,000 from any outside entity, measured on a rolling 12‐month […]

Which angle of light will heat the wood the most? 90° angle Why can you see objects placed under a heat lamp which emits infrared radiation? Infrared waves have longer wavelengths than visible light and can pass through dense regions of gas and dust in space with less scattering and absorption. Thus, infrared energy can […]

What is the most difficult form of abuse to identify? Emotional abuse What happens if you ignore CPS? Q: Do parents have the right to refuse entry to an investigator? A: Yes. But refusing entry to CPS will not end the investigation. If CPS has information that a child may be in danger, they have […]
