Answer:

The entropy change AS, for an ideal gas is given by: dt V Where T is the thermodynamic temperature, V is the volume and R=8.314. Determine the entropy change when a gas expands from 1 litre to 3 litres for a temperature rise from 100K to 400K given that: Cv = 45 + 6 x 10-T + 8 x 10-6T2 b) The average value of a complex voltage waveform is given by: V = ( 10 (10sin ox +3sin 30x +2 sin 508) dt Evaluate Vav correct to 2 decimal places.

Answer:

y=x+20

Step-by-step explanation:

we have to find the slope

y2-y1/x2-x1

3-2/23-22

1/1

y=1x+b

y-22 = 1(x-2) + b

y=x+20

A triangle has two sides that measure 4ft and 3ft. Which could be the measure of the third side?
Nezavi [6.7K]
The measure of the third side must be less than the sum of the other two. That property is valid for all triangles.

For this question, call x the measure of the third side. So you must have

x < 4 + 3

x < 7 ft

The only option that satisfies the condition above is

option A) 5 ft.

I hope this helps. =)

How do you explain a diameter of 0.00085 inches using scientific notation
dezoksy [38]

Answer:

8.5 E^{-4} inches

Step-by-step explanation:

        Scientific scientific notation  is where the super small / super large number is multiplied by a 10 (E) to the power of a number. Here, the number is smaller than 8.5 so our power must be negative. As we are making it four "places" bigger, we use the exponent of -4.

Hope this helps, have a nice day! :D

Ask Your Teacher The "random walk" theory of securities prices holds that price movement is disjoint time periods which independ
vodomira [7]

Answer:

A: Since disjoint, P(up AND up AND up) = P(up) P(up) P(up) = .653= .27

A: Disjoint, so previous years have no effect on this year. 1-.65 = .35

A: Same direction; two different probabilities. P(up AND up) = .652 = .42. P(down AND down) = .352= .12. .42 + .12 = .55
