The correct answer to this question is C. nutcracker. A lever is the type of machine that has a fulcrum. So out of all the choices, a nutcracker is most likely the answer. Another example of a lever includes scissors. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.

Once​ Kate's kite reaches a height of 52 ft ​(above her​ hands), it rises no higher but drifts due east in a wind blowing 6 ft d
Andru [333]

Answer:

5.213ft

Explanation:

Z² = x² + y²

x = √(z² - y²)

y = 52ft, dx = 6ft, z = 105ft, dz = ?

d(z² = x² + y²)

2zdz = 2xdx

dz = xdx/z

But x = √(z² - y²)

dz = √(z² - y²)/z * dx

dz = [√(105² - 52²)/105] * 6

dz = √(8521)/ 17.5

dz = 5.213ft

Through which one of the following mediums is the velocity of a sound wave the greatest?
Colt1911 [192]

Answer: <u><em>C. Steel</em></u>

Explanation: <em><u>When a sound wave travels through a solid body consisting</u></em>

<em><u /></em>

<em><u>of an elastic material, the velocity of the wave is relatively</u></em>

<em><u /></em>

<em><u>high. For instance, the velocity of a sound wave traveling</u></em>

<em><u /></em>

<em><u>through steel (which is almost perfectly elastic) is about</u></em>

<em><u /></em>

<em><u>5,060 meters per second. On the other hand, the velocity</u></em>

<em><u /></em>

<em><u>of a sound wave traveling through an inelastic solid is</u></em>

<em><u /></em>

<em><u>relatively low. So, for example, the velocity of a sound wave</u></em>

<em><u /></em>

<em><u>traveling through lead (which is inelastic) is approximately</u></em>

<em><u /></em>

<em><u>1,402 meters per second.</u></em>

<em><u /></em>

<u><em /></u>

Lab: Types of Reactions Assignment: Lab Report
Thepotemich [5.8K]

The types of chemical reactions are as follows:

  • Combination reactions
  • Decomposition reactions
  • Double decomposition
  • Thermal dissociation
  • Redox reactions

<h3>What the are the types of reactions?</h3>

Chemical reactions are changes in which new substances are formed.

The types of chemical reactions are as follows:

  • Combination reactions - these are reactions in which two or more substances combine to form a single compound
  • Decomposition reactions - these are reactions in which a larger compound splits into smaller substances
  • Displacement reactions - these are reactions in which one element or radical replaces another in a compound
  • Double decomposition - these are reactions in which two substances exchange their radicals to form new compounds.
  • Thermal dissociation - these reactions involves heating compounds to split them into smaller substances.
  • Redox reactions - these are reactions in which oxidation and reduction reactions occur simultaneously.

In conclusion, chemical reactions produce new substances.
