Answer: The potential energy associated with a mass attached to a spring depends on how much the spring is stretched or compressed. ... The gravitational force on the mass is −mg (“−” because the force points down). The force is the negative of the slope on the potential energy versus position graph.

Answer:
Describe the process of boiling
Answer:
0.144 J
Explanation:
From the question above,
Total elastic energy of the spring = Kinetic energy of the spring + potential energy of the spring
E' = E.k+Ep...................... Equation 1
Ek = E'-Ep......................... Equation 2
Where E' = total elastic energy, E.k = kinetic energy, E.p = potential energy.
E' = 1/2ke² = 1/2(26.6)(0.12²) = 0.19152 J.
Ep = 1/2ke² = 1/2(26.6)(0.06²)
Ep = 0.04788 J
Therefore,
Ek = 0.19152-0.04788
Ek = 0.144 J
Sine value is defined in the following way
Explanation:
- In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse. Try this Drag any vertex of the triangle and see how the sine of A and C are calculated. The sine function, along with cosine and tangent, is one of the three most common trigonometric functions.
- Let's start with the basic sine function, f (t) = sin(t). This function has an amplitude of 1 because the graph goes one unit up and one unit down from the midline of the graph. This function has a period of 2π because the sine wave repeats every 2π units.

Answer:
viscosity = 0.051725 N/m-s
Explanation:
Given data
diameter = 0.3 m
u(r) = 0.4/r - 1000r m/s
diameter d1 = 2 cm = 0.02 m
diameter d2 = 4 cm = 0.04 m
rotation = 500 rpm
power = 1 w
to find out
fluid viscosity
solution
we have given
u(r) = 0.4/r - 1000r m/s
du/dr = -0.4/r² + 1000
here r = 0.3 /2 = 0.01 m
du /dr = -0.4/(0.01)² + 1000
du/dr = 5000
and
so velocity is
force = viscosity ( 2π×r×L) du/dr
0.026 / 0.02 = viscosity ( 2π× 0.02×0.04) 5000
viscosity = 0.051725 N/m-s
