What is the difference between a law and a theory explain? Generally, laws describe what will happen in a given situation as demonstrable by a mathematical equation, whereas theories describe how the phenomenon happens. What do hypothesis and theory have in common? In science, a theory is a tested, well-substantiated, unifying explanation for a set […]

Is a capacitor a high pass filter? A capacitor can be used as part of a high pass, low pass, or band pass filter, depending on how it’s connected to other parts. For example, a capacitor with a resistor can be a high pass filter: or a low pass filter: Even that by itelf is […]

Which perspective considers the relationship between individuals? Contextual perspective considers the relationship between individuals and their physical, cognitive personality, and social words. Contextual perspective is one of the modern psychological perspectives. The psychodynamic perspective is based on Sigmund Freud thought. What are some current issues in lifespan development? Four important issues in lifespan development are […]

Which air is lighter warm or cold? Hot air is lighter than cold air. The reason fr this is when air gets heated up it expands and becomes less dense than the air surrounding it also the distance between the molecules increases. So the less dense air floats in the much denser air just like […]

What do you understand by frequency and time? Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so […]

What is gamma decay stopped by? Gamma radiation is the most penetrating. It can penetrate air, paper or thin metal. It may only be stopped by many centimetres of lead or many metres of concrete. What is the strongest ionizing radiation? Alpha particles What is the most dangerous type of ionizing radiation? Gamma rays are […]

What does refractive index indicate? Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or […]

Do I have a mental illness or am I just lazy? Being lazy shouldn’t be confused with a serious mental illness. Usually, if you’re just feeling lazy, it’s a passing mood that lasts a day or two. Soon enough, you get up, and gather the energy to go to classes and catch up on your […]

What is intertropical convergence zone in simple words? The Intertropical Convergence Zone, or ITCZ, is the region that circles the Earth, near the equator, where the trade winds of the Northern and Southern Hemispheres come together. The intense sun and warm water of the equator heats the air in the ITCZ, raising its humidity and […]

How do different amino acid sequences affect organisms? The outcome of a frameshift mutation is complete alteration of the amino acid sequence of a protein. Consequently, once it encounters the mutation, the ribosome will read the mRNA sequence differently, which can result in the production of an entirely different sequence of amino acids in the […]
