Why do we need energy to remove an electron? The energy needed to remove an electron from a neutral atom is the ionization energy of that atom. It is easier to remove electrons from atoms with a small ionization energy, so they will form cations more often in chemical reactions. What would happen if an […]
What are the signs of a timing belt going bad?
What happens if we drink expired beer?
What happens if we drink expired beer? Expired alcohol doesn’t make you sick. If you drink liquor after it’s been open for more than a year, you generally only risk a duller taste. Flat beer typically tastes off and may upset your stomach, whereas spoiled wine usually tastes vinegary or nutty but isn’t harmful. Can […]
What is the goal of a psychologist?
What is the goal of a psychologist? In the broadest of terms, a psychologist’s goal is to study and treat people who have mental illnesses or emotional difficulties, or to provide research on human behavior and how people think. There are three main types of psychologists – research, counseling and applied – and many specializations. […]
Does voltage change when resistance increases?
Does voltage change when resistance increases? As long as the power supply stays constant when resistance is added voltage will increase. If we increase the value in ohms of the resistor, the voltage across the battery terminal and the resistor remains the same. However, due to the increased resistance, we now have less current flowing […]
What are the 4 types of thermodynamic processes?
What are the 4 types of thermodynamic processes? The four types of thermodynamic process are isobaric, isochoric, isothermal and adiabatic. What is an example of thermodynamic process? In this process energy may be transferred form or into the system and also work can be done by or on the system. One example of a thermodynamic […]
Why do horses run until they die?
Why do horses run until they die? Yes, horses can run themselves to death. While running, horses place their cardiovascular and respiratory systems under a lot of pressure, which could, in some situations, lead to a heart attack, stroke, or respiratory failure, and lead to death. Do horses really need shoes? Domestic horses do not […]
What is the equivalent capacitance of the system of capacitors between A and B?
What is the equivalent capacitance of the system of capacitors between A and B? So the equivalent capacitance is 1.6C. What is the net capacitance between A and B of this combination? So, we have only 2 capacitors present in parallel combination amidst A and B terminals. How do you find the net capacitance? For […]
What factors make fossilization more likely?
What factors make fossilization more likely? Because most decay and fragmentation occurs at the surface, the main factor that contributes to fossilization is quick burial. Marine animals that die near a river delta may be buried by sediment carried by the river. What rocks are you most likely to find fossils in? sedimentary rock What […]
When can the addition of two vectors be zero?
When can the addition of two vectors be zero? Yes, two vectors of equal magnitude that are pointing in opposite directions will sum to zero. Two vectors of unequal magnitude can never sum to zero. If they point along the same line, since their magnitudes are different, the sum will not be zero. What does […]
