Answer: σ = 2.47 × 10^-8 q/m²

Explanation: The electric field intensity and surface charge density for an infinite sheet is given as

E =σ/2ε₀

Where E = 1.4KN/c = 1400 N/c

ε₀ = permittivity of free space = 8.85×10^-12

σ = surface charge density

1400 = σ/2×8.85×10^-12

σ = 1400 × 2 × 8.85×10^-12

σ = 24780×10^-12

σ = 2.47 × 10^-8 q/m²

The surgery would not be a hip replacement but would be resetting the broken bone with pins ad wires at late-stage Alzheimer's disease.

Older adults who have surgery with well-known anesthesia can also enjoy a modest acceleration of cognitive decline, even years later. but there may be no proof of a hyperlink to Alzheimer's disease, in step with new research from Mayo sanatorium.

Older adults who have surgical treatment with fashionable anesthesia can also experience a modest acceleration of cognitive decline, even years later. but there's no evidence of a link to Alzheimer's sickness, according to new research from Mayo sanatorium. most hip fractures require surgical treatment, generally within one of damage. hardly ever, hip fractures can be handled without surgical operation, usually in patients who may be too unwell or in a small group of patients that have recovery, non-displaced fractures that have been diagnosed weeks after injury.

Which statement best explains why a wet saw used to cut through a fine optical crystals is constantly lubricated with oil
daser333 [38]

The major reason why a wet saw that is used in cutting optical crystals is constantly lubricated with oil is largely due to friction, lubrication decreases friction and minimises the increase of internal energy.

Friction is basically the coming together of two parts that rubs against each other, it causes heat and lead to  deterioration of surfaces, it can also lead to wear and tear.

Although, despite it down side, friction is desire-able in most applications

e.g the brake system of vehicles, and if not for friction, we humans cannot walk without falling
