Answer:

Rt = 908.25 [ohm]

Explanation:

In order to solve this problem, we must remember that the resistors connected in series are added up arithmetically.

In this case, R2 and R3 are in series therefore.

R₂₃ = 200 + 470

R₂₃ = 670 [ohm]

Now this new resistor (R₂₃) is connected in parallel with the resistor R4. therefore we must use the following arithmetic expression, to add resistances in parallel.

\frac{1}{R_{4-23} }= \frac{1}{R_{4}}+\frac{1}{R_{23} }   \\\frac{1}{R_{4-23} }=\frac{1}{1800}+\frac{1}{670}  \\R_{4-23}=488.25[ohm]

In this way R₁, R₅ and R₄₋₂₃ are connected in series.

Rt = R₁ + R₅ + R₄₋₂₃

Rt = 150 + 270 + 488.25

Rt = 908.25 [ohm]

What is the average speed of an object that travels 50 meters in 2 seconds? Select one: a. 100 m/s b. 25 m/s c. 50 m/s d. 2 m/s
AURORKA [14]

Answer:

Average speed, v = 25 m/s

Explanation:

It is given that,

Distance travelled by the object, d = 50 meters

Time taken, t = 2 seconds

Average speed is defined as the total distance divided by total time taken i.e.

v=\dfrac{d}{t}

v=\dfrac{50\ m}{2\ s}

v = 25 m/s

So, the sped of the object is 25 m/s. Hence, this is the required solution.

Sound intensity, I, from a spherical source is a function of the distance, r, from the source of the sound. It is represented by
quester [9]

A study assessing the effect of anxiety Sound intensity, I, from a spherical source is a function of the distance, r, from the source of the sound.

Everyone experiences anxiety occasionally, but persistent anxiety can reduce your quality of life. Though likely best known for altering behavior, worry can have negative effects on our physical spherical. Anxiety speeds up our heartbeat and breathing, concentrating blood flow to the parts of our brains that need it. You are spherical ready for a challenging situation by having this extremely bodily reaction. Test performance may be impacted by anxiety. According to studies, spherical with low levels of test anxiety perform better on multiple-choice question (MCQ) exams than pupils with high levels of anxiety. Studies have indicated that female students have greater levels of test anxiety than male students.

Helium gas contained in a piston cylinder assembly undergoes an isentropic polytropic process from the given initial state with
jeyben [28]

Answer:

Heat transfer during the process = 0

Work done during the process = - 371.87 KJ

Explanation:

Initial pressure P_{1} = 0.02 bar

Initial temperature T_{1} = 200 K

Final pressure P_{2} = 0.14 bar

Gas constant for helium R = 2.077 \frac{KJ}{kg k}

This is an isentropic polytropic process so temperature - pressure relationship is given by the following formula,

\frac{T_{2} }{T_{1} } = [\frac{P_{2} }{P_{1} } ]^{\frac{\gamma - 1}{\gamma} }

Put all the values in above formula we get,

⇒ \frac{T_{2} }{200} = [\frac{0.14 }{0.02 } ]^{\frac{1.4 - 1}{1.4} }

⇒  \frac{T_{2} }{200} = 1.74

⇒ T_{2} = 348.72 K

This is the final temperature of helium.

For isentropic polytropic process heat transfer to the system is zero.

⇒ ΔQ = 0

Work done W = m × ( T_{1} - T_{2} ) × \frac{R}{\gamma - 1}

⇒ W = 1 × ( 200 - 348.72 ) × \frac{2.077}{1.4 - 1}

⇒ W = 371.87 KJ

This is the work done in this process. here negative sign shows that work is done on the gas in the compression of gas.
