Solve for v: -v+1=1 + 8v
1 answer:
Answer: v=0
Step-by-step explanation:
Because....
Step 1: Simplify both sides of the equation.
−v+ 1= 8v + 1
Step 2: Subtract 8v from both sides.
−v+1 − 8v = 8v+1 − 8v
−9v + 1 = 1
Step 3: Subtract 1 from both sides.
−9v + 1 −1 = 1−1
−9v=0
Step 4: Divide both sides by -9.
v=0
Therefor, the answer is v = 0

Answer:
<h2>16kg</h2>Step-by-step explanation:
This problem is borers on elasticity of materials.
according to Hooke's law,<em> "provided the elastic limit of an elastic material is not exceeded the the extension e is directly proportional to the applied force."</em>
where F is the applied force in N
k is the spring constant N/m
e is the extension in meters
Given data
mass m= 24kg
extensnion=15cm in meters= =
we can solve for the spring constant k
we also know that the force F = mg
assuming
therefore
We can use this value of k to solve for the mass that will cause an extension of
