Dolphins are capable of learning skills based on human instruction and expressing certain desires. Any dolphin trainer will tell you that dolphins and humans can indeed communicate in a limited in fashion. Do we understand dolphin […]
Which state of matter has the greatest amount of molecular motion?
Which state of matter has the greatest amount of molecular motion? gas What has the greatest molecular motion? They are in constant motion and also different from molecules such as liquid molecules have more freedom of movement compared to solid molecules. At the same time they show less movement compared to gaseous molecules. In other […]
Which Cannot be separated physically?
Which Cannot be separated physically? What is a Pure Substance? It is something which cannot be divided into parts by physical means, as it’s all made up of the same thing. Pure substances are either elements or compounds. Elements can NOT be separated into other types of matter (physically or chemically). What are the examples […]
Why is it important to have a reference point?
Why is it important to have a reference point? A reference point is important in determining motion because in order to say that something is moving, you need to have something stationary to compare it to. Is the cyclist accelerating How do you know? How do you know the cyclist is accelerating? a graph of […]

What is the relationship between half-life and decay constant?
What is the relationship between half-life and decay constant? This shows that the population decays exponentially at a rate that depends on the decay constant. The time required for half of the original population of radioactive atoms to decay is called the half-life. The relationship between the half-life, T1/2, and the decay constant is given […]
Where is modulation used?
Where is modulation used? The primary purpose of modulation in a communication system is to generate a modulated signal suited to the characteristics of a transmission channel. In radio communications, modulation is needed in the transmission systems to transfer the message into the available high frequency radio channel. Is LTE FM or AM? Casual analog […]

Which is brighter bulbs in series or parallel?
Which is brighter bulbs in series or parallel? Bulbs in parallel are brighter than bulbs in series. In a parallel circuit the voltage for each bulb is the same as the voltage in the circuit. Unscrewing one bulb has no effect on the other bulb. Which bulb will glow brighter in parallel? Key Points: In […]
What happens to plate A as it collides with plate B?
What happens to plate A as it collides with plate B? Answer: The volcanic arc is formed to “plate A” as it collides with “plate B”. The collision of these two plates results in the oceanic current which is generated. The earthquake is produced because of the volcanic arc creation between the plate A and […]
