A geologist finds a small mineral fragment with a volume of 2.57 cm3 and a mass of

Sindrei [870]

The density of the mineral fragment is

(20.47 g/cm3).

Density can be regarded as<em> ratio of mass to the volume </em>of the object.

Density = (mass/ volume)

Given:

volume of mineral fragments= 2.57 cm3

mass = 52.6 g

density of the mineral fragment = (52.6/2.57)

= 20.47 g/cm3

Therefore, density of the mineral fragment is (20.47 g/cm3)

A person applies a force of 200 N over 1.5 m to a jack. The jack exerts a 1000-N force on a car a distance of 0.02 m. What is th

xz_007 [3.2K]

Answer:

The efficiency rating of the jack is 0.067.

Explanation:

We have, a person applies a force of 200 N over 1.5 m to a jack. The jack exerts a 1000-N force on a car a distance of 0.02 m.

It is required to find the the efficiency rating of the jack. It is equal to the ratio of output work to the ratio of input work. So,

$\eta=\dfrac{1000\times 0.02}{200\times 1.5}\\\\\eta=0.067$

Thus, the efficiency rating of the jack is 0.067.
