1 m3 of saturated liquid water at 200°C is expanded isothermally in a closed system until its quality is 80 percent. Determine t

Jlenok [28]

Answer: Total work produced = 1.355 × 10^5 KJ

Explanation:

Substance :H2O, V1=1m3

State1= sat. liquid, T1=200°C, x1=0

State2= sat.mixture, T1=200°C, x2= 0.8

v1=vf=0.001157m3/kg, vg=0.12721m3/kg

P1=P2=Psat. =1554.9 KPa

v2= vf+x2 (vg-vf) =0.001157 +0.8(0.12721-0.001157)=0.102m3/kg

V2= V1×v2/v1 = 1× 0.102/0.001157 =88.159m3

W= P(V1-V2) =1554.9(88.152- 1) = 1.355x10^5KJ

The moon’s orbital speed around Earth is 3.680 × 10^3 km/h. Suppose the moon suffers a perfectly elastic collision with a comet

Naily [24]

Answer:

Speed of comet before collision is

$v_{2_{i}}=-2.5\times10^{3}\quad km/h$

Explanation:

Correction: (As stated after collision comet moves away from moon so velocity of moon and moon and comet must be opposite in direction. as spped of moon after collision is −4.40 × 10^2km/h so that comet's must be 5.740 × 10^3km/h instead of -5.740 × 10^3km/h)

Solution:

$mass \quad of\quad moon = m_{1}\\\\mass\quad of \quad comet = m_{2} = 0.5 m_{1}\\\\speed\quad of\quad moon\quad before\quad collision = v_{1_{i}}=3.680\times 10^3 km/h\\\\speed \quad of\quad moon\quad after\quad collision=v_{1_{f}} = -4.40 \times 10^2 km/h\\\\speed\quad of\quad comet\quad after\quad collision =v_{2_{f}} =5.740 \times 10^3 km/h$

Case is considered as partially inelastic collision, by conservation of momentum

$m_{1}v_{1_{i}}+m_{2}v_{2_{i}}=m_{1}v_{1_{f}}+m_{2}v_{2_{f}}\\\\m_{1}v_{1_{i}}+0.5m_{1}v_{2_{i}}=m_{1}v_{1_{f}}+0.5m_{1}v_{2_{f}}\\\\v_{1_{i}}+0.5v_{2_{i}}=v_{1_{f}}+0.5v_{2_{f}}\\\\v_{2_{i}}=2(v_{1_{f}}+0.5v_{2_{f}}-v_{1_{i}})\\\\v_{2_{i}}=2(-4.40 \times 10^2+0.5(5.740 \times 10^3)-3.680 \times 10^3 )\\\\v_{2_{i}}=-2.5\times10^{3}\quad km/h$

2. (1 point) Two metal spheres with different radii are each hanging from insulating nylon threads. One of the spheres has a net

DiKsa [7]

Answer:

A. attract each other

Explanation:

When the neutral sphere is brought close to the negatively charged, as charges can move freely in a conductor, some electrons will be repelled, leaving a net positive charge (equal in magnitude ot the charge in the other sphere) on the surface of the neutral sphere, which will cause that both spheres attract each other.

A sprain ..

Ksenya-84 [330]

A sprain is a stretch and/or tear of a ligament. It would cause pain but wouldn't actually dislocate anything. It's not the most painful injury, it can be healed, and stretching would help but not completely avoid a sprain. So that's why D is the answer.
