A piston-cylinder arrangement contains air modeled as an ideal gas with constant specific heat ration of k =1.4. The air undergo

es a power cycle consisting of four processes in series: Process 1 to 2: constant temperature expansion at 600 k from p_1 = 0.5 MPa to p_2 = 0.4 MPa. Process 2 to 3: Polytrophic expansion with n = k to p_3 = 0.3 MPa Process 3 to 4: constant pressure compression to V_4 =V_1 Process 4 to 1: constant volume heating. Sketch the cycle on a p-v diagram. Determine (a) the work and heat transfer of each process in kJ/kg and (b) the thermal efficiency.

When a constant force acts upon an object, the acceleration of the object varies inversely with its mass 2kg. When a certain con
BARSIC [14]

Answer:

The acceleration of the second object is 4 m/s².

Explanation:

Given that,

when the a constant force acts upon an object, the acceleration varies inversely with its mass .

mass\propto \frac{1}{acceleration}

We can rewrite the equation as

\frac{m_1}{m_2}=\frac{a_2}{a_1}

When an a certain constant force acts upon an object with mass 2 kg , the acceleration of the object is 26 m/s².

Here, m_1 = 2 kg, a_1 = 26 m/s²,m_2 = 13 kg and a_2=?

\frac{m_1}{m_2}=\frac{a_2}{a_1}

\frac{2}{13}=\frac{a_2}{26}

\Rightarrow \frac{a_2}{26}= \frac{2}{13}

\Rightarrow {a_2}= \frac{2}{13}\times 26

\Rightarrow a_2=4 m/s²

The acceleration of the second object is 4 m/s².

what does a velocity vs time graph look like for constant velocity if the speed is 2m/s. And the time is not given.
Ulleksa [173]
Distance-time graph is the plot of distance travelled by a body against time. So it will tell us about the journey made by a body and its speed. Below is an example of a distance-time graph, if it is a straight horizontal line than the body is stationary, its speed is zero, if the line is diagonal than its moving with a constant speed and if it is anything other than a straight line then the speed is varying.
