Answer: Refrigeration

Explanation: Food preservation is the technique of preserving food items from spoiling. It is done by preventing the growth of microorganisms and preventing the rancidity of fats.

In ancient times, the methods used for preservation of foods were drying foods which remove water and thus reduces the bacterial growth, smoking raw meats also hampers the bacterial activity and salt curing leads to osmosis and thus the bacteria dies.

The latest method is refrigeration which makes the food colder and the rate of deterioration gets slow. Bacterial action reduces with refrigeration, as bacteria cannot survive at low temperatures.

A mine elevator cage with a mass of 2.5 tons empty is descending at a rate of 32 km/hr when the hoist mechanism jams and stops s

True [87]

Answer:

σ = 4.1 MPa

Explanation:

Given that

m= 2.5 kg

v= 32 km.hr

v= 8.88 m/s

The kinetic energy of the mass ,KE

KE = mv²/2

KE = 2.5 x 8.88²/2

KE= 98.56 J -------1

The strain energy of the string

$E=\dfrac{\sigma^2}{2E}AL$

$E=\dfrac{\sigma^2}{2\times 84,000\times 10^6}\times 6.5\times 10^{-4}\times 1500$

$E={\sigma^2}\times {5.80\times 10^{-12}}$ ----2

KE= E

$98.56={\sigma^2}\times {5.80\times 10^{-12}}$

$\sigma =\sqrt{\dfrac{98.56}{5.80\times 10^{-12}}}$

σ = 4.1 MPa

<span>Like most Earth materials, rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. </span><span>All rocks are made up of minerals. A mineral is defined as a naturally occurring, crystalline solid of definite chemical composition and a characteristic crystal structure. A rock is any naturally formed, nonliving, firm, and coherent aggregate mass of solid matter that constitutes part of a planet. i don't know if this is right but i hope it helps</span>
