Answer:Physics. Distance, the total distance an object travels dependent on its path through space. Optical path length, the product of the distance light travels and the refractive index of the medium it travels through. Mean free path, the average distance that a particle travels before scattering.
Explanation:
Your list that you call "the following properties" is awfully short. / / / The displayed value tells you the car's speed relative to the pavement. (NOT its velocity.)
Answer:
A glass flask whose volume is 1000 cm ^3 at 0.0 ^oC is completely filled with mercury at this. Every substance when heat energy is supplied, expands due to the Rate of thermal expansion will be different for different materials. Volume of the glass flask and mercury at 0 degree Celsius V0=1000cm3=1×10−3m3 V 0

Answer:
1.18266×10⁻²⁰ J
Explanation:
Applying,
E = (3/2)kT.................... Equation 1
Where E = kinetic energy of the gas molecule, k = Boltzmann's constant, T = Temperature
But,
PV = nRT.............. Equation 2
Where P = pressure, V = Volume, n = number of moles, R = Universal gas constant.
make T the subject of the equation
T = PV/nR............. Equation 3
Substitute equation 3 into equation 1
E = (3/2)k(PV/nR)
E = 3kPV/2nR............... Equation 4
Given: k = 1.38066×10⁻²³ J/K, V = 6.6 L = 0.0066 m³, P = 7.1 atm = (101325×7.1) N/m² = 719407.5 N/m², n = 2.9 mol, R = 8.31451 J/K.mol
Substitute into equation 4
E = (3×1.38066×10⁻²³×0.0066×719407.5)/(2×8.31451)
E = 1182.66×10⁻²³ J
E = 1.18266×10⁻²⁰ J
