The forces of friction acting on the object are <u>12.67 N.</u>
<u />
Friction is the force resisting the relative motion of sturdy surfaces, fluid layers, and material factors sliding towards each specific. There are numerous styles of friction. Dry friction is a strain that opposes the relative lateral movement of two stable surfaces in touch.
<u>Calculation:-</u>
ma - 14.2 N = Friction force
14.2 N - 0.45 × 3.41 = <u>12.67 N</u>
Friction is the shape of contact pressure. It exists between the surfaces that are in touch. The frictional force relies upon the character of the floor in contact. The rougher the ground, the extra friction is involved. The frictional force is proportional to the urgent pressure, which is the burden of the body. it's miles impartial of the place of the touch.
A function that assigns a numerical value to each outcome of an experiment is described as a random variable. Random variables helps to determine the outcome of a random event.
Example of a random event is tossing of die, casting of a coin.
Random variables ascribe numerical values to the outcome of an experiment.
They are often used in probability to determine the extent of the certainty of an experimental procedure.
