What is the equation of SHM? Equations Equation Symbols Meaning in words x ( t ) = A cos ( 2 π f t ) x(t) = A\cos(2 \pi f t) x(t)=Acos(2πft) x x x is displacement as a function of time, A is amplitude, f is frequency, and t is time Displacement as […]
Which animal dispersed seeds the farthest?
Which animal dispersed seeds the farthest? Micronesian Starlings Why is Dispersal a good thing? Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area […]
Is the relationship between pressure and volume direct?
Is the relationship between pressure and volume direct? Boyle’s law states that pressure (P) and volume (V) are inversely proportional. Charles’ law states that volume (V) and temperature (T) are directly proportional. Gay-Lussac’s law states that pressure (P) and temperature (T) are directly proportional. What is the relationship between temperature pressure and volume? Key Concepts […]
What does T1 and T2 mean on MRI?
What does T1 and T2 mean on MRI? The most common MRI sequences are T1-weighted and T2-weighted scans. T1-weighted images are produced by using short TE and TR times. Conversely, T2-weighted images are produced by using longer TE and TR times. In these images, the contrast and brightness are predominately determined by the T2 properties […]
What are the 4 functions of the atmosphere?
What are the 4 functions of the atmosphere? Atmosphere is essential for life on Earth as it supplies oxygen, water, CO2 and some nutrients (N) to living organisms, and protects living organisms from temperature extremes and excessive UV radiation. Up to about 80 km, the composition of atmosphere is highly uniform; therefore, the term homosphere […]
What do waves carry from place to place?
What do waves carry from place to place? What is a wave? Waves carry energy from one place to another. Because waves carry energy, some waves are used for communication, eg radio and television waves and mobile telephone signals. There are many types of waves including sound waves, water waves and all the parts of […]
What are Capricorns like sexually?
What are Capricorns like sexually? Their sex is earthy and straightforward, sometimes lacking in romance and sentimentality. Sometimes Capricorn will surprise you in sex, becoming as aggressive and dominant in asking for what they want in the erotic realm as they are in their profession. Are Capricorns good in bed? That said, Capricorns also have […]
How does depolarization and repolarization occur in the heart?
How does depolarization and repolarization occur in the heart? In the heart, electrical activity (depolarization and repolarization) proceeds in a sequential manner. From the SA node, the wave of depolarization moves through both atria (P wave), resulting in atrial contraction. What is the difference between depolarization and repolarization of the heart? The main difference between […]
Is a fan mechanical energy?
Is a fan mechanical energy? A fan always uses mechanical energy, that’s why, when you turn it off, it eventually stops spinning, and it would even if it were frictionless, because the built up mechanical energy (rotational kinetic energy) gets used up from continuing to move air. What is a fact about mechanical energy? The […]
Does electricity need a complete circuit to flow?
Does electricity need a complete circuit to flow? The wires in a circuit carry the electric current to various parts of an electrical or electronic system. For electrons to do their job in producing light, there must be a complete circuit so they can flow through the light bulb and then back out. Can current […]
