Question

A body of mass $m$ is thrown at an angle $θ$ to the horizontal with the initial velocity $v_{0}$ . Assuming the air drag to be negligible, find the momentum increment $Δ p$ that the body acquires over the first $t$ seconds of motion.

Δ p = m g t

Solution

The correct option is C $Δ p = m g t$
Change in momentum will be equal to the impulse being imparted on it .
$△ p = F \times t$
$△ p = m \times g \times t$

If splitting energy is higher than the pairing energy (∆s >∆p) in an octahedral complex

Then will the electrons pair up or will they not?

I am confused because

In the video, it was said that they'll pair up if ∆p>∆s

And in my book, it's written that they'll pair up if ∆s>∆p
