Answer:
0.5×10² pm
Explanation:
Given data:
Frequency of x-ray = 6×10¹⁸ Hz
Wavelength of x-ray = ?
Solution:
Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.
Formula:
speed of wave = wavelength × frequency
speed = 3×10⁸ m/s
now we will put the values in formula.
3×10⁸ m/s = λ × 6×10¹⁸ Hz
Hz = s⁻¹
λ = 3×10⁸ m/s / 6×10¹⁸ s⁻¹
λ = 0.5×10⁻¹⁰ m
m to pm
0.5×10⁻¹⁰ m × 10¹² pm/1m
0.5×10² pm
Answer:34.28 Degree celcius
Explanation:The heat given is equal to the change in temperature multiplied by the mass and the specific heat capacity
This gives the equation:Q=mc∆T
Where Q=184,m=7, specific heat capacity=4.184,∆T=X-28,
But ∆T=Final temperature (T'')-Initial temperature (T')
Therefore the equation becomes
184=7×4.184(X-28)
Solving the remaining linear equation gives you X as 34.28°C

Because the easier a metal donates an electron (Low Ionization Energy), the more readily a non-metal with high electromagnetically will accept it.
Thus they match well, - one readily donates, the other readily accepts. This is how ionic bonding occurs.
Hope this helps.
