In both cases less energy is required
But comparetively Mg require more energy than K
Let's see the electron configuration of Both
- [Mg]=1s²2s²2p⁶3s²=[Ne]3s²
- [K]=1s²2s²2p⁶3s²3p⁶4s¹=[Ar]4s¹
K has only one valence electron so very less ionization enthalpy so less energy required
Mg has 2 so more IE hence more energy required
Nope.
False.
The shift in spectral lines reveals only 'radial' motion ...
motion toward us or away from us. The spectrum
carries no information related to motion across the
line of sight.
Impulse: a certain amount of force you apply for an amount of time.
Impulse: F*t where F= Force & t=time
Momentum: increasing forward motion.
A ball rolling down a slide gains momentum
p=mv where m=mass and v=velocity
Hope it helps!

Answer:
The movement of an object depends on the reference frame, so it is important to predicate it.
