Why Bubbles are not formed in water? Atmospheric gases such as nitrogen and oxygen can dissolve in water. The amount of gas dissolved depends on the temperature of the water and the atmospheric pressure at the air/water interface. Hence bubbles along the insides of your water glass. Where do you think the bubbles came from? […]
What happens at an evidence hearing?
What happens at an evidence hearing? The preliminary hearing is like a mini-trial. The prosecution will call witnesses and introduce evidence, and the defense can cross-examine witnesses. If the judge concludes there is probable cause to believe the crime was committed by the defendant, a trial will soon be scheduled. How do you win a […]
Is Moon hotter than Sun?
Is Moon hotter than Sun? Temperatures on the moon are extreme, ranging from boiling hot to freezing cold depending on where the sun is shining. When sunlight hits the moon’s surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 […]

Why is hydrogen placed in Group 1 and not 17?
Why is hydrogen placed in Group 1 and not 17? Hydrogen is placed above group in the periodic table because it has ns1 electron configuration like the alkali metals. However, it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than the other alkali metals. Hydrogen has a much smaller electron […]
What is the relation between current and resistance?
What is the relation between current and resistance? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. What is a specific resistance? […]
What are the factors that affect soil stability?
What are the factors that affect soil stability? factors influence the size, distribution, and stability of soil aggregates. Among these factors are the method of taking and handling the sample, season of the year, moisture content of the soil at time of sampling, past soil management practices, and method of determining and expressing soil aggregation. […]

Can sound waves bend?
Can sound waves bend? Sound waves do, indeed, bend. In an underwater thermal gradient the sonar waves can bend enough to create blind spots, so that you can not “see” a target that would ordinarily be well within sonar range. The other example is the difference in how well sound carries up/down wind. What is […]
What is the two main function of a diode?
What is the two main function of a diode? Main functions The most common function of a diode is to allow an electric current to pass in one direction (called the diode’s forward direction), while blocking it in the opposite direction (the reverse direction). As such, the diode can be viewed as an electronic version […]
