What do radio waves visible light and gamma rays all have in common? Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of […]
What are the pros and cons of CBT?
What are the pros and cons of CBT? Research has shown that cognitive behavioural therapy (CBT) can be as effective as medication in treating Anxiety & Depression problems. There is always a risk that bad feelings you associate with your problem will return, but with your CBT skills it should be easier for you to […]
What does the slope of displacement time graph gives?
What does the slope of displacement time graph gives? A sloping line on a displacement-time graph shows that the object is moving. In a displacement-time graph, the slope or gradient of the line, is equal to the velocity of the object. The steeper the line (and the greater the gradient) the faster the object is […]
What is a circuit chart?
What is a circuit chart? What is a Circuit Diagram? A circuit diagram is a visual display of an electrical circuit using either basic images of parts or industry standard symbols. A schematic style circuit diagram is used to give a visual representation of an electrical circuit to an electrician. What are the two types […]
What is wavelength called?
What is wavelength called? Wavelength is commonly designated by the Greek letter lambda (Ī»). The term wavelength is also sometimes applied to modulated waves, and to the sinusoidal envelopes of modulated waves or waves formed by interference of several sinusoids. What is the formula of Hertz? Physical value symbol unit Cycle duration T = 1 […]
What are the different stimuli?
What are the different stimuli? excited by three types of stimuliāmechanical, thermal, and chemical; some endings respond primarily to one type of stimulation, whereas other endings can detect all types. Chemical substances produced by the body that excite pain receptors include bradykinin, serotonin, and histamine. What are some examples of stimuli? Stimuli include: Irritants. Sights. […]
WHAT IS units in chemistry?
WHAT IS units in chemistry? Chemistry primarily uses five of the base units: the mole for amount, the kilogram for mass, the meter for length, the second for time, and the kelvin for temperature. The degree Celsius (oC) is also commonly used for temperature. What is the formula to convert kg to lbs? 1 Kilogram […]
Why are unit tests useless?
Why are unit tests useless? Unit tests ossify the internal structure of the code. All the unit tests are suddenly rendered useless. Some test code may be reused but all in all the entire test suite has to be rewritten. This means that unit tests increase maintenance liabilities because they are less resilient against code […]
Is there a weight limit for private pilots?
Is there a weight limit for private pilots? In the US there’s no specific weight limit in the regulations. Instead, they just say that you must be capable of performing the duties of a pilot, e.g. 14 CFR 61.113: A very heavy pilot may be too heavy to fly in some smaller aircraft (including training […]
Does the Earth accelerate towards you?
Does the Earth accelerate towards you? Earth accelerates towards you So the mass of the Earth relative to you is incredibly large. From Newton’s second law of motion we know that for a given force on an object the acceleration reduces as the mass of the object increases. However the Earth still accelerates towards you […]
