<u><em>Plasma is the fourth state of matter. it is found throughout the universe but rarely on planet Earth. Plasma is a gaslike state caused when either radiation or very high temperatures slip electrons away from atoms. Plasma is a great conductor for heat and electricity. You can find plasma inside of a star.</em></u>

Answer:

b) 252 Hz or 260 Hz

c) 0.25 s

Explanation:

b) The frequency of the beats is 4 Hz, and one tuning fork has a frequency of 256 Hz.  Therefore, the second tuning fork is either 4 Hz lower or 4 Hz higher.

f = 252 Hz or 260 Hz

c) Period is the inverse of frequency.

T = 1/f

T = 1 / (4 Hz)

T = 0.25 s

What type of rock is limestone? Describe how a limestone rock is likely to change over a long period of time.
tatuchka [14]

Answer:

Limestone is a sedimentary rock

Explanation:

1. Limestone is a carbonate sedimentary rock made up of calcite(CaCO₃).This rock type forms calcareous shells and tests of organisms that was deposited in a sedimentary basin.

Limestone is used in building and construction works. It also finds application in chemical industries.

2. Over a long period of time, we would take a look at the rock "limestone" through the rock cycle.

Limestone being a sedimentary rock would be converted to marble, a metamorphic rock if subjected to metamorphic conditions over an extensive period of time. With series of metamorphic transformation, marble can grade to higher metamorphic facies of rocks as it combines with other minerals in the crust. The minerals would eventually change and as the changed rock approaches its melting temperature, melt would result.

From the other spectrum, limestone can be weathered if subjected extensively to denudation forces such as wind, water and glaciation. Water is more potent for the chemical weathering of limestone. Limestone would easily and readily dissolve in it over a long period of time.

What impulse must be applied to a 25.0-kg cart to cause a velocity change<br> of 12.0 m/s?
klio [65]

Answer:

Impulse of force = 300Ns

Explanation:

Given the following data;

Mass = 25kg

Change in velocity = 12m/s

To find the impulse;

Impulse is given by the formula;

Impulse \; of \; force = mass * change \; in \; velocity

Substituting into the equation, we have;

Impulse \; of \; force = 25 * 12

Impulse of force = 300Ns
