Answer:
Explanation:
We need 2 different equations for this problem: first the velocity of sound equation, then the frequency of the sound equation.
The velocity of sound is found in:
v = 331.5 + .606T
We need to find that first in order to fill it into the frequency equation which is
where v is the velocity we will find the part a, f is frequency and lambda is the wavelength. Starting with the velocity of the sound:
v = 331.5 + .606(25) and
v = 331.5 + 15 and rounding correctly using the rules for sig fig when adding:
v = 347 m/s
Filling that into the frequency equation:
and
so
Solution :
The electric field between two plates is given by
where
permitivity of free space
q = charge
A = surface area
It is given that :
the radius of the circular plates , r = 30 mm
the current, I = 0.43 mA
Therefore, Magnetic field can be found by
A reaction at dynamic equilibrium<span> can be reversible, whereas a reaction at </span>static equilibrium<span> is irreversible. A reversible reaction is a reaction that can proceed in the direction of products to reactants. ... It is at </span>static equilibrium<span> if the reaction has occurred and the forward and reaction rates are both equal to 0.
hope this helps!</span>

<h2>A rainbow is caused by sunlight and atmospheric conditions. Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths--or colors. When light exits the droplet, it makes a rainbow.</h2>
Answer:
so these are
either 3 to 2 or 2 to 1 or 3 to 1
Explanation:
As we know that total number photons emitted from nth state to ground state is given by
here it shows that if electron has transition from nth excited state to ground state then total number of photons is given by above equation
here we know that higher state is n = 3
so total number of photons is given as
so these are
either 3 to 2 or 2 to 1 or 3 to 1
