What is the most successful cancer treatment? 1. Revlimid. Top of the best cancer drug list is Celgene’s Revlimid (lenalidomide). This drug has been very successful in the treatment of multiple myeloma as it promotes immune responses that slow tumour growth. Do cancer patients sleep a lot? Evidence is accumulating that sleep is often disturbed […]

How many years are in an era? An era in geology is a time of several hundred million years. It describes a long series of rock strata which geologists decide should be given a name. An example is the Mesozoic era, when dinosaurs lived on the Earth. An era is made up of periods, and […]

What are the two boundary conditions for infinite potential well? A particle under the influence of such a potential is free (no forces) between x = 0 and x = a, and is completely excluded (infinite potential) outside that region. What is a difference between finite and infinite potential well? In the infinite potential well, […]

How do you calculate magnification on a light microscope? To calculate the total magnification of the compound light microscope multiply the magnification power of the ocular lens by the power of the objective lens. For instance, a 10x ocular and a 40x objective would have a 400x total magnification. The highest total magnification for a […]

What is the body has begun shivering what happens to make it stop? After the body has begun shivering, what explains why it would stop shivering? When body temperature returns to normal, the respiratory system sends a message to the skeletal system to stop shaking. When body temperature returns to normal, the nervous system sends […]

Can final year students apply for ISRO 2020? Tech degree with at least 65% marks in aggregate or CGPA 6.84/10 (average of all semesters for which results are available). Final Year: Candidates who are in the final year of the qualifying degree can also apply provided they can produce the same by the time the […]

How many hours exactly is a day? 23 hours How is day calculated? Day can be defined as each of the twenty-four-hour periods, reckoned from one midnight to the next, into which a week, month, or year is divided, and corresponding to a rotation of the earth on its axis. Why is a day not […]

What are the three variables in a science experiment? There are three main variables: independent variable, dependent variable and controlled variables. What is a controlled variable example? Examples of Controlled Variables Temperature is a common type of controlled variable. If a temperature is held constant during an experiment, it is controlled. Other examples of controlled […]

What happens to impedance when frequency increases? As the frequency increase, the reactance decreases. As the frequency increases, the impedance increases. These are referred to as inductive reactance and capacitive reactance. Impedance is a crucial concept to understand as most electronic circuits utilize capacitors and inductors. What is the difference between impedance and resistance? Resistance […]

Does fire destroy atoms? No, atoms don’t burn. No fire on Earth would destroy an atom. Fires typically are a function of the heat of chemical reactions. For instance, burning wood takes a carbon and hydrogen based material and forms carbon dioxide and water out of these atoms, plus heat. How many atoms does fire […]
