Can machine change the direction of force? Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. That’s because a machine doesn’t change the amount of work and work equals force times distance. […]
How entropy is a measure of disorder?
How entropy is a measure of disorder? Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system. The concept of entropy provides deep insight into the direction of spontaneous change for many everyday phenomena. Does entropy mean disorder? Entropy is […]

What is your biggest failure or challenge? How to answer “What is your biggest failure?” Choose a specific failure. Pick a real failure that happened in the workplace, specifically a failure related to the work you’re doing now. Share your story. Share with the interviewer the story you chose.

How do you interpret a negative Pearson correlation?
How do you interpret a negative Pearson correlation? Negative Correlation A negative (inverse) correlation occurs when the correlation coefficient is less than 0. This is an indication that both variables move in the opposite direction. In short, any reading between 0 and -1 means that the two securities move in opposite directions. What is negative […]
What do you get when you reverse an exothermic reaction?
What do you get when you reverse an exothermic reaction? If the forward reaction is exothermic the reverse reaction will be endothermic, and if the forward reaction is endothermic the reverse reaction will be exothermic. A reaction that produces no change in temperature in an insulated container is said to be athermal. What is forward […]
What are 5 ways to conserve energy?
What are derived units give examples?
What are derived units give examples? Answer. Definition: A derived unit is a SI unit ofmeasurement comprised of a combination of the seven base units. Examples: The SI unit of force is the derived unit newton or N. A newton is equal to 1 m. What are derived quantities give examples? Derived quantities are the […]
Why is hemoglobin so important?
Why is hemoglobin so important? Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues. Myoglobin, in muscle cells, accepts, stores, transports and releases oxygen. What organ makes hemoglobin? Hemoglobin is produced in bone marrow by erythrocytes and is circulated with them until their destruction. It is then broken down […]
What are the balls on powerlines?
What are the balls on powerlines? They’re called visibility marker balls or marker balls. You’ll often find them near mountain passes, in the deep valley areas, near major freeway crossings and around airports. They weight about 17 pounds each. The marker balls are placed on power lines to make the conductor crossings visible to aircraft. […]
Can metaphors use as?
Can metaphors use as? This means that you cannot use the word “as” to establish a metaphor. When it establishes a comparison, that comparison is explicit. When it does not establish the comparison, that comparison may be implicit and therefore may be a metaphor. You can’t have metaphor and comparison at the same time. What […]
