Iliotibial band syndrome occurs when a tendon called the iliotibial band rubs against the hip or knee bones, causing it to become inflamed or swollen. The tendon runs from the top of your pelvic bone down to your knee on the outside of your leg. When it becomes overly tense, it grinds on your bones (tight).
The repetitive bending of the knee during physical activities such as running, cycling, swimming, and hiking is a common cause of iliotibial (IT) band syndrome. Fascia, or connective tissue, makes up the IT band. It is an elastic collection of fibers that extends from the hip to below the knee along the thigh.

Two technicians are discussing a resistance measurement between the can-h and can-l wires. Technician a says this measurement should be done with the ignition switch in the "run" position. Technician b states that a measurement of 0 ohms indicates an open in the network. Which technician is correct?
Based on the information given, the technician that's correct regarding the resistance measurement between the wires is Technician A.
Who is a technician?It should be noted that a technician simply means an individual that's in charge of looking after the technical equipment in an organization.
In this case, Technician A is correct. Technician B is incorrect as zero-ohm doesn't indicate an open circuit in the network but rather, a complete circuit.

What factors do NOT affect friction between two objects? Explain how you know this.
Answer:
Friction does not depend on the amount of surface area in contact between the moving bodies or (within certain limits) on the relative speed of the bodies. It does, however, depend on the magnitude of the forces holding the bodies together.

8. A 55-kg skateboarder enters a ramp moving horizontally with a speed of 6.5 m/s, and leaves the ramp moving vertically with a speed of 4.1 m/s. (A) Find the height of the ramp, assuming no energy loss to frictional forces. (B) What is the skateboarder's maximum height above the bottom of the ramp?
(a) The energy lost to friction by the skateboarder is -699.6 J.
(b) The maximum height above the bottom of the ramp is 1.3 m.
Energy loss to frictionThe energy lost to friction by the skateboarder is calculated from the change in kinetic energy of the skateboarder.
ΔK.E = K.Ef - K.Ei
ΔK.E = ¹/₂m(vi² - vf²)
ΔK.E = 0.5 x 55 (4.1² - 6.5²)
ΔK.E = -699.6 J
Maximum height above the bottom of the rampThe maximum height above the bottom of the ramp is determined from conservation of energy.
mghi + ¹/₂mvi² = ¹/₂mvf² + mghf
55 x 9.8 x hi + (0.5 x 55 x 6.5²) = (0.5 x 55 x 4.1²) + (55 x 9.8 x 0)
539hi + 1161.88 = 462.28
539hi = -699.6
hi = -699.6/539
hi = -1.3 m
Thus, the maximum height above the bottom of the ramp is 1.3 m.

A post driver has a mass of 10kg. Calculate the change in GPE stored when the post driver is lifted by 50cm above the post. The gravitational field strength on earth is 10N/kg.
Answer:
500kJ
Explanation:
Common equation;
GPE = mgh
m = mass - in kg
g = gravitational field strength - in N/kg
h = height lifted/lowered - in meters
GPE = 10kg × 10N/kg × 5000m
GPE = 500000Nm
GPE = 500000J
GPE = 500kJ

Hilda looks at a cd and sees different colors. Which best explains why she sees different colors when light strikes a cd?.
Answer:
The smooth surface of the CD causes wavelengths of light to scatter. The CD at this point acts somewhat like a prism splitting white light into the colors of the rainbow. This is called the visible spectrum of light and is composed of the colors red, orange, yellow, green, blue, indigo and violet.
Explanation:
Answer: The reflected wave has less energy
Explanation:
The incident wave would be the light wave before it comes in contact with the CD. Once the incident wave hits the CD, there is a reflected wave which will have some portion of energy from the incident wave. The reflected wave is a different color from the incident wave due to the reflected wave having less energy. Less energy means a different wavelength of visible light

A car bounces up and down on its springs at 1.0 Hz with only the driver in the car. Now the driver is joined by four friends. The new frequency of oscillation when the car bounces on its springs is
The new frequency of oscillation when the car bounces on its springs is 0.447 Hz
Frequency of oscillation of spring
The frequency of oscillation of the spring is given by f = (1/2π)√(k/m) where
k = spring constant and m = mass on springNow since k is constant, and f ∝ 1/√m.
So, we have f₂/f₁ = √(m₁/m₂) where
f₁ = initial frequency of spring = 1.0 Hz, m₁ = mass of driver, f₂ = final frequency of spring and m₂ = mass on spring when driver is joined by 4 friends = 5m₁So, making f₂ subject of the formula, we have
f₂ = [√(m₁/m₂)]f₁
Substituting the values of the variables into the equation, we have
f₂ = [√(m₁/m₂)]f₁
f₂ = [√(m₁/5m₁)]1.0 Hz
f₂ = [√(1/5)]1.0 Hz
f₂ = 1.0 Hz/√5
f₂ = 1.0 Hz/2.236
f₂ = 0.447 Hz
So, the new frequency of oscillation when the car bounces on its springs is 0.447 Hz
