A fisherman uses a spring scale to weigh a tilapia fish. He records the fish weight as a kilograms and notices that the spring stretches b centimeters. Which expression represents the spring constant (1 =9.8 )? A). 980ab B). 9.8ab C). 9.8ab D). 980ab
Answers
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 =

The measure of side SQ from the given similar triangles is 40.9 units.
What are similar triangles?
Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
Given that, triangle NOP is similar to triangle QRS.
Since the triangles are similar,
NP/SQ = NQ/QR
10/SQ = 13/53.2
13SQ=532
SQ=532/13
SQ=40.9 units
Therefore, the measure of side SQ is 40.9 units.

C is correct
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Angle L is an obtuse angle, as all angles in an equilateral pentagon are obtuse.
Also, all other statements are false:
A) The two lines are not parallel, as they would eventually intersect
B) This angle is not acute, as it is more than 90 degrees
D) These lines are not perp., as they do not form right angles at their intersection
So your answer is C! Hope it helps!
