Agas obeys the ideal-gas equation of state pv =nkt, wheren=nnaisthenumber of molecules in the volume v at pressure p and temperature t and n is the number of gm-moles of the gas. calculate the volume occupied by 1 gm·mole of the gas at atmospheric pressure and a temperature of 341.3 k. avogadro’s constant is 6.02214 × 1023 mol−1 , boltz- mann’s constant is 1.38065 × 10−23 n · m/k , and1atm=1.013×105 n/m2. answer in units of l.

number of electrons for neutral cl

answer; equivalent to a one(1) horsepower motor;

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
