A solid cylinder of mass 2 kg and radius 0.2 m is rotating about its own axis without friction with angular velocity 5 rad/s. A particle of mass 1 kg moving with a velocity of 5 m/s strikes the cylinder and sticks to it as shown in figure.
The angular velocity of the system after the particle sticks to it will be:
Active transport is a type of cellular transport in which molecules (such as glucose, ions, and amino acids) are transferred across a biological membrane to a place where there are already enough of them. As a result, molecules are moved across concentration gradients using chemical energy (for instance, ATP). Root hair cells and the small intestine wall are persistent active transport sites (villi).
There are two types of active transportation mechanisms such as;
