Determine the mass of the object below to the correct degree of precision.
OleMash [197]

Answer : The correct degree of precision is 272.94 g.

Explanation :

Precision : It is defined as the closeness of two or more measurements to each other.

For Example: If you weigh a given substance five times and you get 2.7 kg each time. Then the measurement is said to be precise.

Level of precision is determined by the maximum number of decimal places.

In the given figure, the value of mass of object is 280 g. From the given options we conclude that the 272.94 g is more close to 280 g and has maximum number of decimal places. So, 272.94 g measurement is said to be precise.

Therefore, the correct degree of precision is 272.94 g.

A box that is resting on an inclined plane has what forces acting on it
miskamm [114]

A box residing on an inclined plane has following forces:

In the X- direction

Mg sin (theta) = horizontal  component of weight of the box

f = Frictional force = uN , u = frictional factor, N= mg

In the Y- direction

upward force = Normal reaction of the box = mg

downward force = mg cos(theta) = vertical component of weight of the box
