cheese?

A) 0 N
B) 14N
C) 20 N
D) 26 N

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

prndulum needs thread, weight clock to time swings

3. dark matter

empty space could also be a simple vacuum
