Which of the following is an example of impact force? Answer: A bowling ball striking a set of pins is an example of impact force. Explanation: Impact force is when two or more bodies collide. How do you find the force of impact? F = m * v² / (2 * d) , F is […]
What is the difference between a qualitative and quantitative analysis?
What is the difference between a qualitative and quantitative analysis? Let’s differentiate between the two. Qualitative analysis fundamentally means to measure something by its quality rather than quantity. Quantitative analysis is the opposite; to measure by quantity rather than quality. When we do quantitative analysis, we are exploring facts, measures, numbers and percentages. Why quantitative […]
What are the qualities of a proportional relationship?
What are the qualities of a proportional relationship? Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the “constant of proportionality”. What are four ways […]
What does it smell like when lightning?
What does it smell like when lightning? The smell is probably ozone, which typically has a sweet, pungent aroma. In stormy weather, lightning splits atmospheric nitrogen and oxygen molecules. These can then combine into nitric oxide, which, with further reactions, forms ozone. Can you taste lightning? Though it may sound strange, you may taste something […]
What is the unit of Hall coefficient?
What is the unit of Hall coefficient? The two most widely used units for the Hall coefficients are SI units, m3/A-sec = m3/C, and the hybrid unit Ohm-cm/G (which combines the practical quantities volt and amp with the cgs quantities centimeter and Gauss). How do you calculate Hall effect? Hall Voltage for Positive Charge Carriers […]
How much elastic potential energy is stored in the spring?
What are the forces that enable a pendulum bob to swing?
What are the forces that enable a pendulum bob to swing? In pendulum motion, three forces work directly on the pendulum: the mass of the bob, gravity and the tension in the string. Mass and gravity both work vertically downward. Does the pendulum tell the truth? Like muscle testing, your body itself is its own […]
What is the distance light travels in one year called?
What is the definition of impulse buying?
What is the definition of impulse buying? Definition: Impulsive buying is the tendency of a customer to buy goods and services without planning in advance. When a customer takes such buying decisions at the spur of the moment, it is usually triggered by emotions and feelings. Impulsive buying means making an unplanned purchase. What is […]
Does an apple attract Earth towards it?
Does an apple attract Earth towards it? The Earth attracts an apple and so does the apple attracts the earth with an equal and opposite force. Mass of the Earth is extremely massive as compared to that of the moon. So, the acceleration produced is very small as compared to that in the apple. Hence, […]
