v20.1

A parallel plate capacitor is constructed with plates of area 0.0280 m^(2) and separation 0.550 mm . Find the magnitude of the charge on each plate of this capacitor when the potential between the plates is 20.1 V

The velocity of a body depends on time according to the equative v = 20 + 0.1 t^(2) . The body is undergoing

The velocity fo a body depends on time according to equation, v= 20 + 0.1 t^2 . The body is undergoing.

A vessel of volume V = 20 1 contains a mixture of hydrogen and helium at a temperature t = 20 ^@C and pressure p = 2.0 atm . The mass of the mixture is equal is equal to m = 5.0 g . Find the ratio of the mass of hydrogen to that of helium in the given mixture.

When a 2 kg car driven at 20 m//s on a level road is suddenly put into netural gear (i.e. allowed to coast), the velocity decreases in the following manner: V=20/(1+(t/20))m//s Where t is time in sec. The deceleration of car at the instant its speed is 10 m//s is.

Two insulting plates are both uniformly charged in such a way that the potential difference between them is V_2-V_1=20V . (i.e., plate 2 is at a higher potential). The plates are separated by d=0.1m and can be treated as infinity large. An electron is released from rest on the inner surface of plate 1. What is its speed when it hits plate 2? ( e=1.6xx10^-19C , m_e=9.11xx10^-31kg )

Based on the data given for half cell (M^(x+n)+ , M^(x+) || Pt % of reduced form 50 20 Potential (V) 0.1, 0.112 the value of n is:
