According to ________ law, in a sealed chamber, the pressure and temperature of a gas are directly related to each other.
irinina [24]
The answer to this question is the "Gay Lussac's Law". This law stated that the pressure and temperature is directly related to each other such that when the pressure increases, the temperature will also increase and vise versa, in short they are directly related. This explanation can be expressed as P1 / T1 = P2 / T2.

Leto [7]

Answer:

Answer

Explanation:

In a LCR Circuit, the phase difference between voltage and current is usually summarized as;

tan∅ =<u> XL- XC</u>

               R

     =<u>WL - 1/WC</u>

            R

When w=0 ( i.e when it is very low)    tan∅ = ∞

                                                         or      ∅ = -90

When w=0 ( i.e when it is very large)    tan∅ =+ ∞

                                                         or         ∅ = +90

A string trimmer is a tool for cutting grass and weeds; it utilizes a length of nylon "string" that rotates about an axis perpen
olga2289 [7]

Answer:

0.28899 m

Explanation:

v = Velocity = 69 m/s

\omega = Angular velocity = 39\times 2\pi\ rad/s

r = Radius of the motion

In rotational motion velocity is given by

v=r\omega

\\\Rightarrow r=\dfrac{v}{\omega}

\\\Rightarrow r=\dfrac{69}{38\times 2\pi}

\\\Rightarrow r=0.28899\ m

The length of the rotation string is 0.28899 m
