Polarization is defined as the property of electromagnetic radiations where the relationship between the direction and magnitude of the vibrating... View Article
Escape velocity does not depend on the mass of the body as well as the direction of projection of the body. It only depends on the mass and the... View Article
Answer: The viscosity of liquids decreases with increase in temperature. Viscosity is defined as the measure of the resistance of a fluid to... View Article
The speed of flow of blood through constricted artery is raised which lowers the pressure inside and the artery may collapse due to external pressure.... View Article
Answer: Venturimeter is a device used to measure the rate of flow of fluid flowing through a pipe. Venturimeter is a device which is used for... View Article
The rate of flow of liquid through an orifice at the bottom of a tank does not depend on the density of liquid, acceleration due to gravity and... View Article
In summers, co-efficient of viscocity of liquid decreases with rise in temperature and in winters, co-efficient of viscocity of liquid increases... View Article
According to Bernoulli's theorem, when velocity of flow increases, the pressure decreases hence the higher-pressure pushes the balls together.... View Article
The dynamic lift due to spinning is called the Magnus effect. Dynamic lift is defined as the normal force acting on a body by the virtue of its... View Article
Bernoulli's theorem states that for the streamline flow of an ideal liquid, the total energy (the sum of the pressure energy, potential energy... View Article
Bernoulli's theorem is important in the field of the flow of liquids. Bernoulli's principle can be summarized as 'total pressure is constant... View Article
In case of streamlined flow of liquid, the loss of energy is minimum because different layers glide over one another without intermixing.... View Article
A body is said to be perfectly elastic if it recovers its original shape/size when the deforming force is removed. Elasticity is the property... View Article
Tangential force is defined as the force acting on a moving body in the direction of the tangent to the curved path of the body.  If the velocity... View Article
