Mostly scientist are willing to design intelligent hypothesis based on the existing knowledge. Given the scenario that most science (SPECIALLY BIOLOGY) is non -linear system, nature wants it on that way. Trying to put theory into practice sometime does not match, which makes things diverse and need to think outside box.
We often hear that objects appear to be weightless in a spaceship circling round the Earth. In order to examine the effect in some detail, let us first define, what do we mean by the weight? The real weight of an object is the gravitational pull of the Earth on the object.
If a body is spinning about an axis with constant angular velocity ώ, each point of the body is moving in a circular path and, therefore, has some K.E. to determine the total K.E. of a spinning body,
A semiconductor is a material that produces electrical transference between conductor and insulator. Semiconductor mostly deal with electron and in other, it deals with electron holes. Both are called charge carrier. Some are very good conductor, e.g.
In that case quests can also leave. So there is never any actual way of knowing which room is occupied at any given time, or in any given room. Unless you monitor every room all the time. Not to mention, that even a hypothetical hotel will never finish being built, if the idea is for it to have infinite rooms.
When can we multiply and add physical quantities? And what do we exactly mean, by the way, by the product of the number and the sum of the number? I’ve been to many math lessons in high school but so far my teachers haven’t made it clear yet.
The rocket gains momentum equal to the momentum of the gas expelled from the engine but in opposite direction. The rocket engines continue to expel gases after the rocket has begun moving and hence rocket continues to gain more and more momentum. So instead so travelling at steady speed the rocket gets faster and faster so long the engines are operating.
The law of conservation of angular momentum is one of the fundamental principles of physics. It has been verified from the cosmological to the submicroscopic level. The effect of the law of conservation of angular momentum is readily apparent if a single isolated spinning body alters its moment of inertia. This is illustrated by the diver in Fig. 5.13.
A particle is said to possess an angular momentum about a reference axis if it so moves that it’s angular position changes relative to that reference axis.
The angular momentum L of a particle of mass m moving with velocity v and momentum p (Fig. 5.10) relative to the origin O is defined as
The motion of a particle which is constrained to move in a circular path is quite interesting. It has direct bearing on the motion of such things as artificial and natural satellites, nuclear particles in accelerators, bodies whirling at the ends of the strings and flywheels spinning on the shafts.
