What can longitudinal waves not travel through? Longitudinal waves are like mechanical waves which need the medium to propagate. These waves cannot travel through a vacuum. That is, there is absolutely in a vacuum. If there are no substances, then there are no particles for the sound waves to vibrate, which means the sound waves […]
What is the most difficult form of abuse to identify?
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 […]
How does a person move forward during swimming?
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 is an example of contraction?
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 […]

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 […]
How do you calculate the no load speed of a DC motor?
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 […]
Why is current constant in a parallel circuit?
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 the difference between positive reinforcement and positive punishment?
What is the difference between positive reinforcement and positive punishment? Instead, positive means you are adding something, and negative means you are taking something away. Reinforcement means you are increasing a behavior, and punishment means you are decreasing a behavior. All reinforcers (positive or negative) increase the likelihood of a behavioral response. How do you […]
What do the arrows in a food chain represent quizlet?
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 […]
What information does the slope of the line in a distance time graph give?
What information does the slope of the line in a distance time graph give? The slope of the distance-time graph indicates speed. It is because the slope of a distance-time graph determines the speed of that body, so the steeper the slope greater will be the speed of the body. What is the physical meaning […]
