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:
A) 3
Step-by-step explanation:
12 * 2 = 24
8 * 3 = 24
24 = 24
50 miles = 1 hour
50 x 1 = 50
a. 50 miles x 2 hours = 100 miles
b. 50 miles x 4.3 hours = 215 miles
c. Converting minutes to hours, it would make 20 minutes become 0.333 hours.
50 x 0.333 = 16.65 miles
Answer:
Step-by-step explanation:
theres 2 possible solutions for each equation and each one is right
or for dummies, just reverse the +/- inside the l x +/- y l. and make 2 different equations the first with a + and the second with a -
1. lb-6l = 1
b - 6 = 1
b = 7
-----------
b + 6 = 1
b = -5
--------------
2. lb+2l=7
b + 2 = 7
b = 5
--------------
b - 2 = 7
b = 9
---------------
Answer:
Yes
Step-by-step explanation:
Slope intercept form is:
y=mx+b
where m is the slope, and b is the y intercept
We are given the slope, it is -3. We are also given the y intercept, (0,4). In this form, the 0 in (0,4) is ignored, and our y intercept is considered to be 4.
Therefore, m is -3, and b is 4.
y=mx+b
y=-3x+4
So, your answer is correct.
