Answer:
686.7 N
Step-by-step explanation:
mass the person is 70 kg , which is constant for the entire universe.Although weight of the person is depends upon the gravity of the planet on which he resides
W= mg
m= mass W= wight and g= Acceleration due to gravity of the planet which 9.81 m/sec^2 on earth.
therefore weight W = 70×9.81 = 686.7 N
Hence the weight of the father will be 686.7 N
Answer:
4n+(2n-9)
4n+2n-9
6n-9 =the total age
6n=9
divide by 6 both sides.
n=9/6
n=1.5 years.
substitute the value of n in the age of the father and the daughter.
Age of father=4×1.5
6years.
Age of Daughter = (2×1.5)-9
3-9
=-6 years
Total age
6-6=0
