Catalysts are of two Kinds, positive Catalysts and Poisons (inhibitors).
A positive catalyst affects the rate of reaction by decreasing the activation energy or energy barrier that must be overcome before the reaction. It does this by providing an alternative pathway for a reaction to occur so products are formed faster than it would.
All the best.

Momentum of a body is given by :
P = mv
P can be varied by varying either m or v. Since mass of a body is a constant quantity so we can change momentum of a body by changing its velocity.
Momentum will be increased by 20% if the velocity is changed by 20%, since its a linear relation between the two.
Let
mass = m = 10kg
velocity = v = 100m/s
Momentum with these values = P = 1000 kgm/s
K.E with these values = K.E = 50000 J
After 20% increase velocity becomes = v' = 120m/s
so new momentum = 1200 kgm/s
Change in momentum = (1200-1000)/1000 x 100%
= 0.2 x 100%
= 20%
New K.E = 72000 J
Change in K.E = (72000 - 50000)/50000 x 100%
=

Symbol F. A capacitor has a capacitance of 1 farad if a charge of 1 coulomb increases the potential difference between its plates by 1 volt. The farad is coulombvolt, or in terms of base units only, The farad is much too big for most practical purposes; microfarads, nanofarads, and picofarads are usually used.
All the best.

Dielectric constant of a medium is the ability of the medium to loosen the bond of any electrovalent compound immersed in it. Higher the dielectric constant, higher is the solubility of substances in that medium. Water has a high dielectric constant, it is also called a universal solvent. Even a very small amount of glass is also soluble in water.
All the best.
