Answer:62.5 J
Explanation:
Given
Inductance(L)=5 H
resistance(R)
Voltage(V)=100 V
Current in L-R circuit is given by
![I=I_0\left [ 1-e^{-\frac{Rt}{L}}\right ]](https://tex.z-dn.net/?f=I%3DI_0%5Cleft%20%5B%201-e%5E%7B-%5Cfrac%7BRt%7D%7BL%7D%7D%5Cright%20%5D)
and Power=i^2R+Li\frac{di}{dt}[/tex]
For Steady state i.e. at
Energy Stored is 
Answer:
In ionic compounds, electrons are transferred between atoms of different elements ... For example, two hydrogen atoms bond covalently to form an H2 molecule; each ... is released when one mole of H2 molecules forms from two moles of H atoms: ... atom in each pair is more electronegative: (a) N or P. (b) N or Ge. (c) S or F.

Answer:
b) The star is moving away from us.
Explanation:
If an object moves toward us, the light waves it emits are compressed - the wavelength of the light will be shorter, making the light bluer. On the other hand, if an object moves away from us, the light waves are stretched, making it redder. If from laboratory measurements we know that a specific hydrogen spectral line appears at the wavelength of 121.6 nanometers (nm) and the spectrum of a particular star shows the same hydrogen line appearing at the wavelength of 121.8 nm, we can conclude that the star is moving away from npos, since the wavelength related to that star is more expanded.

Explanation:
need thanks and make me brainiest if it helps you
We are given with the data that the angle of velocity is above the negative axis. hence, the angle lies in the second quadrant with negative x axis and positive y axis. In this case, the x component is -12 cos 60 equal to -6 m/s while the y-component is 12 sin 60 equal to 6 sqrt of 3 m/s.
