Distinguish between linear momentum and angular momentum.
Katarina [22]

Linear momentum is in a straight line and depends on the objects mass and velocity.

Angular (rotational) momentum depends on the objects mass, velocity, and radius.

Calculate the wavelength of light emitted when each of the following n=5 n=3
denis-greek [22]
When it transmits from n=5 to n=3, 
∧ = Rh [ni - nf]
∧ = Rh [1/3-1/5]
∧ = Rh 2/15

So, your final answer is Rh * 2/15
Where, Rh = Rydberg's constant

Hope this helps!

A plano concave lens is one that has a surface that curves inward, making the lens thinner at its center than at its edges. Its
katrin2010 [14]

Answer:

b.) the diverge in incident beam of light

Explanation:

A lens refers to any refracting surface. The manner in which a lens is curved tells whether it is a concave(diverging) lens or a convex (converging) lens.

A convex lens is thicker at the center than at the edges. It makes light to converge at a point.

A concave lens is is thinner at the center than at the edges. It makes light to appear to diverge from a point, hence the answer above.

Use this technique to find a formula for the intensity I of a sound, in terms of the sound level β and the reference intensity I
denis23 [38]

Answer:

I = I_o (10^{\frac{\beta}{10}})

Explanation:

As we know that sound level is given as

\beta = 10 Log (\frac{I}{I_o})

so here we have

\frac{\beta}{10} = Log(\frac{I}{I_o})

now we can take anti log both sides

10^{\frac{\beta}{10}} = \frac{I}{I_o}

so we have

I = I_o (10^{\frac{\beta}{10}})

so above is the expression for the intensity of sound in terms of reference intensity and sound level
