A sample of a diatomic ideal gas has pressure P and volume V. When the gas is warmed, its pressure triples and its volume double

Answer:

Amount of Energy transferred $=8.5PV$

Explanation:

Given:

Initial volume=V

Initial pressure=P

Final volume=2V

Final pressure=3P

Now w know that the Energy transferred in constant pressure pressure is given by

$E_1=nc_pdT\\\\E_1=n\times\dfrac{7R}{2}dT\\E_1=3.5(nRdT)\\E_1=3.5(V(2P-P))\\E_1=3.5PV$

Now the Energy transferred in constant volume process is given by

$E_2=nc_vdT\\\\E_2=n\times\dfrac{5R}{2}dT\\E_1=2.5(nRdT)\\E_1=2.5(V(3V-V))\\E_1=5PV$

The total Energy transferred is given by

$E_{total}=E_1+E_2\\E{total}=3.5PV+5PV\\=8.5PV$

Radar is used to determine distances to various objects by measuring the round-trip time for an echo from the object. (a) How fa

BartSMP [9]

Answer

given,

Echo time = t = 1000 s

speed = ?

$v = \dfrac{d}{t}$

a) speed of electromagnetic wave

$c = \dfrac{d}{t}$

wave travels Venus two time

$c = \dfrac{2d}{t}$

$d = \dfrac{ct}{2}$

$d = \dfrac{3 \times 10^8\times 1000}{2}$

d = 1.5 x 10¹¹ m

b) now, echo time

$c = \dfrac{2d}{t}$

$t = \dfrac{2d}{c}$

$t = \dfrac{2\times 75}{3 \times 10^8}$

t = 5 x 10⁻⁷ s

If 730-nm and 640-nm light passes through two slits 0.61 mm apart, how far apart are the second-order fringes for these two wave

Naddik [55]

Answer:

X2 - X2'=3.24×10⁻⁴m

Explanation:

Given Data

λ1=730nm=

λ2=640nm

d=0.61 mm

D=1.1 m

Distance of the second bright fringe from the central fringe is given by

Xn = = D x n x2 λ / d

X2 = 2 D λ1 / d

X2' = 2 D λ2 / d

Separation between the second bright fringes of the two wavelengths ( the separation between the second order fringes ) is ,

X2 - X2' = 2 D ( λ1 - λ2 ) / d

X2 - X2'= {2 x 1. 1 (730×10^-9 - 640×10^-9) }/ 0.61 x 10 ^-3

X2 - X2'=3.24×10⁻⁴m

How was the age of the Earth determined? (site 1)

Fudgin [204]

HEllO PAIGE❤️

The age of earth is determined truly by the RADIOCARBON MATHOD . In this method we can find the actuall age of anything having carbon .

Hope it helps you.
