Well, we don't know if it's the CLOSEST one, but it's closer than the other ones on this print-out.

There are actually three clues to this in the seismograms:

1). The waves from the tremor reach the Wink station first ... the P wave gets there 50 seconds before Chicago and 3 whole minutes before Tampa.

2). They are stronger (greater amplitude) at Wink than at Chicago or Tampa.

3). The delay between the P wave and the S wave is the smallest at Wink. This delay between the two waves grows as the detector is farther from the quake.

Refrigerant-134a enters the condenser of a residential heat pump at 800 kPA and 35oC at a rate of 0.018 kg/s and leaves at 800 k

Assoli18 [71]

Answer:

(A) COP = 2.64

(B) rate of heat absorption= 1.9637 kW

Explanation:

mass flow rate (m) = 0.018 kg/s

work input (Win) = 1.2kW

inlet pressure (P1) = 800kPa

inlet temperature (T1) = 35 degree Celsius

h1 = 271.24 KJ/Kg

outlet pressure (P2) = 800 kPa

outlet temperature (T2) = ?

entalphy (h2) = 95.48 KJ/Kg

The entalphies are gotten from tables for refrigerant 134a at the temperatures and pressures above

(A) COP = Qh ÷ Win

where Qh = m(h1 -h2) from the energy balance equation

Qh = 0.018 ( 271.24 - 95.48 ) = 3.1637 kW

COP = 3.1637 ÷ 1.2 = 2.64

(B) rate of heat absorption = Qh - Win

= 3.1637 - 1.2 = 1.9637 kW

8. If a circuit has a current of 25.4 amps with 12.6

grin007 [14]

The resistance of the circuit is $0.496 \Omega$

Explanation:

We can solve the problem by applying Ohm's law, which gives us the relationship between current, potential difference and resistance in a circuit:

$V=RI$

where

V is the potential difference

R is the resistance

I is the current

For the circuit in this problem,

V = 12.6 V

I = 25.4 A

Re-arranging the equation, we can solve for the resistance:

$R=\frac{V}{I}=\frac{12.6}{25.4}=0.496 \Omega$

A 3.90 kg block is in equilibrium on an incline of 31.0◦. The acceleration of gravity is 9.81 m/s2 . What is Fn of the incline o

storchak [24]

Answer:

Explanation:

The sum of the pore along the plane is expressed according to Newton's law

Fn-Ff = ma

Fn is the moving force

Ff = nR = frictional force

m is the Mass

a is the acceleration

Substitute the given values

Fn - nR = ma

Fn - tan31°(mgcostheta) =3.9(9.8)

Fn - tan31(3.9(9.8)cos31) = 3.9(9.8)

Fn - tan31(38.22cos31)= 38.22

Fn - 32.76tan31 = 38.22

Fn-19.68 = 38.22

Fn = 38.22+19.68.

Fn = 57.90N

Hence Fn (moving force) of the inclined block is 57.90
