Hey guys if anyone can help that would be amazing, this is due at noon​

a.45N

b.52.2N

c.36.45N

Explanation:

note:these answers are based on the fact that the acceleration due to gravity is 10m/s²

*.first of all the tension (T)in the cable is equivalent to the mass(m) of object multiplied by the sum of the opposite and parallel accelerations of the gravity and the elevator respectively.ie. g and a

now that being said mathematically the formula for tension in the cable is given by

T=m(g+a).

a).now for this situation the elevator is stationary,thus has not accelerated,

so a=0

then T=mg; where m=4.5kg g=10ms-²

therefore, T=4.5*10=45N.

b).here the elevator accelerated up, so a is positive.ie.+a

hence T=4.5(10+1.6)=52.2N.

c).here also the elevator accelerated down, so a is negative. is.-a

hence T=4.5(10-1.9)=36.25N.

I hope this will be of good help to you, you can contact me for further explanations or questions.
