What is the mechanical advantage of a machine that applies a force of 1000 N to an object when a force of 500 N is applied to the machine?

Answers

Answer 1
Answer: The mechanical advantage of the machine in the problem is 2. By definition, the mechanical advantage of a machine is equivalent to the ratio of its output force to its input force. Since it applies a force of 1000 N to an object, that is its output. Also, since a 500 N force is applied to the machine, that is its input. So 1000/500 = 2.
Answer 2
Answer:

Answer: 2

Explanation:

  • The mechanical advantage of a machine is defined as the amplification of the force produced when using a machine or a tool.
  • In mathematical terms, it is the ratio of the output force to input force and, the formula is :

       MA = Fo/Fi

       Where MA= mechanical advantage

       Fo= Output force

        Fi = input force.

  • According to  the question, Fo= 1000N

       Fi= 500 N

  • Therefore, MA= 1000/500 = 2

Answers

"Kudzu outcompetes native plants for sunlight and nutrients" was the one role among the choices given in the question that kudzu played in the United States. The correct option among all the options that are given in the question is the third option or option "C". I hope that the answer has helped you.

Answer:

It’s C

Explanation:

Read the passage.(1) New York City has many tourist attractions, but one attraction stands head and shoulders above the rest. (2) It is the Statue of Liberty, also known as Lady Liberty.

Which among the sentences contains a comma splice?


A. sentence (1)
B. sentence (2)
C. sentence (3)
D. sentence (4)

Answers

Sentence (1) contains a comma splice. Therefore, option (A) is correct.

What is comma splice?

A comma splice is an error in grammar that occurs when two independent clauses (complete sentences) are joined by a comma, without the use of a coordinating conjunction (such as "and" or "but"). This error can occur when a writer is trying to connect two ideas or sentences, but does not use the proper punctuation to do so.

In sentence (1), the clauses "New York City has many tourist attractions" and "one attraction stands head and shoulders above the rest" are both independent clauses, but they are joined by a comma instead of a coordinating conjunction. This creates a comma splice.

#SPJ2

A comma splice is basically a comma fault which means- when two independent clauses are joined by a comma to make one complete sentence. And an independent clause is a clause that can stand alone as a sentence.

So, here in the passage- Option C is correct one.

Lady Liberty is a woman holding a torch, it represents freedom. This sentence can be successfully broken into two complete sentences. Like- Lady Liberty is a woman holding a torch. It represents freedom.

Based on this data, predict what will happen to the water in the Ogallala aquifer over the next decade.

Answers

Answer:

The Ogallala Aquifer has a shallow water table and is mostly surrounded by sand particles, silt and clay, and some gravels that are present below the Great Plains in the United States.

It contains about 3 billion acres feet of water but still, it could run dry. it has a total water storage that is equivalent to the Huron Lake that is located in the Midwest.

It is the only source of water within the regions of high plain areas that actually provides the water for residential, industrial, and agricultural use.

This groundwater is already contaminated and slowly getting declined, as a result of which the water in this aquifer will slowly become extinct or unsuitable for any purposes.
