During a lesson in physical science about changes of matter, students made ice cream. among the materials that are required to m

ake ice cream is salt. which answer choice best explains the role of salt in this activity? adding salt to ice lowers the freezing temperature. this helps the milk mixture to freeze sooner because the mixture will reach the freezing temperature sooner. adding salt to the ice raises the freezing temperature. this helps the milk mixture to delay in freezing, giving the ice cream enough time to form and have a great taste. adding salt prevents the milk in the ice cream from going bad and giving the ice cream a bad taste. salt in ice cream preparation is used as a preservative to enable the ice cream to have a longer shelf life.

You are making a telephone out of two aluminum cans and some string. You can choose between two types of string: a 2-m length of
Nataliya [291]

Answer:

C)You should use the thin cooking twine.

Explanation:

A)You can choose either because they are the same length and will produce the same wave speed.

B)You should use the heavy rope.

C)You should use the thin cooking twine.

The speed of wave in a string is given by the following formula:

|v| = \sqrt{\frac{F_T}{u} }

Where |v| = speed of wave, F_T = tension in the string, and μ = mass per length of the string.

<em>Even though the two strings have the same length, the μ (mass/length) for the heavy rope will be more than the that of a thin rope. Consequently, the </em>F_T<em>:μ for the thin rope will be higher than that of the heavy rope and as such, gives a bigger |</em>v<em>|. </em>

Therefore, the thin rope should be used in order to get a faster wave speed in the telephone.

The correct option is C.

solniwko [45]

Answer:

B. Geosphere

A. Biosphere

A. Atmosphere

Explanation:

Volcanic eruptions occurs within the Geosphere. The geosphere is the rock solid earth make up of rocks that extends into the deep interior.

Magma formed deep within the crust rises to elevated parts and finally erupts as lava on the surface. When they cool, they solidify to form volcanic rocks.

The volcanic eruptions affects the biosphere significantly. The biosphere is the portion of the earth where all life forms exists.

Gases and ash spewed during an eruption into the atmosphere causes severe changes to weather and leads to pollution. The atmosphere is the gaseous envelope round the earth.
