Answer:
69,480 kg.m/sExplanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 45 × 1544
We have the final answer as
69,480 kg.m/sHope this helps you

Can one mole of peas fit inside your house? List the materials and steps of an experiment that answers the
question without actually filling up your house with peas!
Answer:
No.

What is the ground-state electron configuration of chlorine and the number of valence electrons in it?
Explanation:
Chlorine is an element in group 7 on the periodic table.
It is the second element in this group of halogens
The element has a total of 17 electrons:
Ground state configuration = 1s² 2s² 2p⁶ 3s² 3p⁵
Valence electrons are the outermost shell electrons;
From the configuration: 3s² 3p⁵ is the valence shell
Number of electrons = 2 + 5 = 7
