Two Methods: During an Acute Bout Further Action. Raise blood pressure by using basic first-aid awareness to alleviate the problem. If you are the patient, these points will enable your feeling better. As the caregiver, you provide a knowledgeable, calming influence to bring the patient past this crisis.
Coefficient of friction. A coefficient of friction is a value that shows the relationship between the force of friction between two objects and the normal force between the objects. It is a value that is sometimes used in physics to find an object's normal force or frictional force when other methods aren't available.
= 0.2. The coefficient of static friction between the body and the plane is 0.2. Question 2: A body of mass 40kg is given an acceleration of 10m/s2 on horizontal ground for which the coefficient of friction is 0.5.Calculate the force required to accelerate the body.ince at the point of sliding, frictional force is proportional to the normal reaction, giving the equation. F = ÂµR. Therefore, Âµ = F/R. /R = /WcosÎ¸ = Âµ. Âµ = /Wcos Î¸. Âµ = tanÎ¸. Therefore, the coefficient of friction, Âµ for a body on an inclined plane is always given as the tangent of the angle of inclination.
