1 answer:

6 0

Corrected question: The wavelength of light beam<u> </u><u>A</u> is twice the wavelength of light beam B. The energy of a photon in beam A is:

Answer:

Explanation:

Energy = hc/λ

λ(A) =2λ(B)...................equation 1

We will solve for the ratio of energy of A to energy of B.which is

$\frac{E_{A} }{E_{B} }$

=(hc/λA) ÷ (hc/λB)

referring to equation 1 we have

=(hc/2λB) ÷ (hc/λB)

=hc/2λB) × (λB/hc)

= λB/2λB

$\frac{E_{A} }{E_{B} }$ =1/2

${E_{A} = \frac{1}{2} E_{B}$

The energy of A is half of B

a pitcher throws a 0.35 kg ball, giving it an acceleration of 10.0 m/s. what would the acceleration be, if the pitcher threw the

german

Answer:

New acceleration is 20.0 m/s².

Explanation:

F = m*a

F = 0.35 kg * 10.0m/s²

If Force will be doubled , and mass will be the same

we can write

2F = 2*0.35 kg*10.0 m/s²=0.35kg*20.0m/s²

New acceleration is 20.0 m/s².

Suppose the voltage source for a series RL-circuit were given as V0sin(ωt) instead of V0cos(ωt). Write an expression for the cur

Gala2k [10]

Answer:

Explanation:

This is an RL circuit, therefore:

Impedance; z = $\mathbf{\sqrt{R^2+L^2}}$

$\mathbf{z = \sqrt{R^2+(Lw)^2}}$

Current amplitude

$\mathbf{I_o = \dfrac{V_o}{z}} \\ \\ \mathbf{I_o = \dfrac{V_o}{\sqrt{R^2+L^2\omega ^2}}}$

Given that:

$V_o = 1.9 \ V \\ \\ \omega= 51 \ rad/s\\\\ R = 21 \Omega \\ \\ L = 0.52 H$

∴

$I_o= \dfrac{1.9}{\sqrt{21^2+(0.52\times 51)^2}}$

$\mathbf{I_o= 0.0562} \\ \\ \mathbf{I_o = 56.2 \ mA}$

Phase constant :

$tan \ \phi = \dfrac{L \omega}{R } \\ \\ tan \ \phi = \dfrac{0.52 \times 51}{21} \\ \\ tan \phi = 1.263$

$\text{Phase constant : }\phi = tan^{-1} (1.263) \\ \\ \phi = 51.6^0\\ \\\text{To radians} \phi = 51.6 \times \dfrac{\pi}{180} \\ \\ \phi = 0.287 \pi \\ \\ \mathbf{\phi = 0.9 \ rad}$

Does time stop in a black hole

lbvjy [14]

Answer:

In standard GR, nothing exists at the center of a black hole. The center of a black hole is a singularity, and because GR fails at that point it is simply removed from the manifold. That means that the singularity is not part of spacetime.

To answer your question more realistically, we believe that GR is an approximate theory that fails well before you reach the center. Unfortunately, we have no good alternative theory with which to answer the question in the region where GR fails. We simply don’t have any data from that regime and it is very hard to formulate a good theory without data. So there very well could be time at the center, but we simply don’t have a good way to even guess.
