What is unusable energy called? In every energy transfer, some amount of energy is lost in a form that is unusable. In most cases, this form is heat energy. Thermodynamically, heat energy is defined as the energy transferred from one system to another that is not doing work. Entropy is a measure of randomness or […]
What is the common ratio of the geometric sequence below 4 8 16 32?
Why animals can reproduce in large number?
Why animals can reproduce in large number? Animals have limited amounts of energy they can use for reproduction. Animals with high fecundity spend their energy in the production of many offspring that do not require much care. Alternatively, animals with low fecundity produce fewer offspring, and have more energy to care for those offspring. What […]
What is an outlier on a scatter diagram?
What is an outlier on a scatter diagram? An outlier is defined as a data point that emanates from a different model than do the rest of the data. If the outlier is omitted from the fitting process, then the resulting fit will be excellent almost everywhere (for all points except the outlying point). What […]
What affects period of a spring?
What affects period of a spring? The period of a spring-mass system is proportional to the square root of the mass and inversely proportional to the square root of the spring constant. What is the formula for oscillation? The period formula, T = 2π√m/k, gives the exact relation between the oscillation time T and the […]
Which medical term best describes shortening or tightening of a muscle?
Which medical term best describes shortening or tightening of a muscle? A muscle contracture involves the shortening and tightening of the muscles. Joints. If there’s contracture in the joint capsule where two or more bones connect, you’ll experience limited range of motion in that area of your body. Skin. Where do muscles end? The moveable […]
What are three important characteristics of light waves?
What are three important characteristics of light waves? There are three measurable properties of wave motion: amplitude, wavelength, and frequency. What are the five main characteristics of light? You’ll also recognize when there’s no pizzazz to the light and, most likely, you will not make so many disappointing images. Photography is “writing with light.” So, […]
Do ribosomes make proteins?
Do ribosomes make proteins? Ribosomes are the sites in a cell in which protein synthesis takes place. Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. Do ribosomes make DNA? Ribosomes are large complexes of protein and ribonucleic acid […]
Why do some object float and others sink?
Why do some object float and others sink? Why do some things float and other things sink? It depends on the density of the object. Density is a measure of both how massive those molecules are, and how closely packed together they are. If the object’s total density is greater than that of water, it […]
