Answer:
k =
Step-by-step explanation:
Fisherman noticed a stretch in the spring = 'b' centimetres
Weight of the fish = a kilograms
If force applied on a spring scale makes a stretch in the spring then Hook's law for the force applied is,
F = kΔx
Where k = spring constant
Δx = stretch in the spring
F = weight applied
F = mg
Here 'm' = mass of the fish
g = gravitational constant
F = a(9.8)
= 9.8a
Δx = b centimetres = 0.01b meters
Therefore, 9.8a = k(0.01b)
k =
k =
Therefore, spring constant of the spring will be determined by the expression, k =
Answer:
n = 8
Step-by-step explanation:
2n - 5 = 11
2n = 11 + 5
2n = 16
n = 16/2
n = 8
Answer:
1220703125
Step-by-step explanation:
it means
=(5^9)*(5^4)
When bases are same powers are to be added so this becomes
=5^(9+4)
=5^13
By using calculator
=1220703125
By not using calculator
=5^13(we can simply write it 13 times)
=5*5*5*5*5*5*5*5*5*5*5*5*5
=1220703125
Answer: 7 backpacks for $8 = $56
7 lots of paper and pens for $5 each = $35
56 + 35 = $91
The student Council savings decreased by $91
