Answer:
26.466cm³/min
Explanation:
Given:
Volume 'V'= 320cm³
P= 95kPa
dP/dt = -11 kPa/minute
pressure P and volume V are related by the equation
P
=C
we need to find dV/dt, so we will differentiate the above equation
![V^{1.4} \frac{dP}{dt} + P\frac{d[V^{1.4} ]}{dt} = \frac{d[C]}{dt}](https://tex.z-dn.net/?f=V%5E%7B1.4%7D%20%5Cfrac%7BdP%7D%7Bdt%7D%20%2B%20P%5Cfrac%7Bd%5BV%5E%7B1.4%7D%20%5D%7D%7Bdt%7D%20%20%3D%20%5Cfrac%7Bd%5BC%5D%7D%7Bdt%7D)

lets solve for dV/dt, we will have

(plugged in all the values at the instant)
= 26.466
Therefore, the volume increasing at the rate of 26.466cm³/min at this instant
Answer:
The frequency would not change because the frequency of a simple pendulum does not depend on mass.
Explanation:
Answer:
X: Use DC
Y: Use AC
Explanation:
The objects: Wall clock, T V remote control, Portable music player, are normally powered by batteries, which run DC current.
On the other hand, the objects: Refrigerator, Table lamp, Hair dryer, demand much larger power, and are normally run from the AC plug on the wall.
With 30degree because incident angle = reflected angle
Answer:
Wavelength, 
Explanation:
We have,
Velocity an electron is 
Mass of an electron is 
It is required to find the wavelength of electron. The De-Broglie wavelength of an electron is given by :

h is Planck's constant

So, the wavelength of an electron is
.
