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 tothe machine?
0.5
2
500
1500

Answers

Answer 1
Answer:

Answer:

2

Explanation:

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.

Answer 2
Answer:

Answer:

the answer is "2"

Explanation:

the answer is "2" because the formula for mechanical advantage is  you divide the distance from the fulcrum, the point at which the lever pivots, to the applied force by the distance from the fulcrum to the resistance force.

Explain how plants and algae use sunlight. how is this process important to other living things in an ecosystem ?

Answers

Plants and algae use sunlight to make food. They do this with the process of photosynthesis, and they create excess oxygen as a waste product. The oxygen is vital for other living organisms to survive and perform their daily functions. Hope this helps :)

If a car can go from 0 to 60 mi/hr in 8.0 seconds, what would be its final speed after 5.0 seconds if its starting speed were 50 mi/hr?

Answers

a= (V)/(t) \ \ \ \Rightarrow\ \ a= (60\ [mi/hr])/(8\ [s]) \n \nthe\ final\ speed\ after\ 5.0\ seconds\n \nV=50\ [mi/hr]+5\ [s]\ \cdot (60\ [mi/hr])/(8\ [s])=50\ [mi/hr] + (5)/(8) \cdot 60\ [mi/hr]=\n \n=50\ [mi/hr]+37.5\ [mi/hr]=87.5\ [mi/hr]
v_1=60\ (mi)/(h)\n\nt_1=8.0\ s=(8)/(3600)\ h=(1)/(450)\ h\n--------------\na=(v)/(t)\n\na=(60)/((1)/(450))\ (mi)/(h^2)=27000\ (mi)/(h^2)\n--------------\nv_o=50\ (mi)/(h)\n\nt=5.0\ s=(5)/(3600)\ h=(1)/(720)\ h\n--------------

v=v_o+at\n\n\nv=50\ (mi)/(h)+27000\ (mi)/(h^2)\cdot(1)/(720)\ h=50\ (mi)/(h)+37.5\ (mi)/(h)=87.5\ (mi)/(h)\leftarrow Answer

What is the voltage in a circuit if the current is 6.2 A and the resistance is 18 ohms

Answers

We already know the formula:
Voltage = Current * Resistance
In the given question, there are numerous information's that are already given.
Current = 6.2 A
Resistance = 18 ohms
Then
Voltage = 6.2 * 18 Volts
             = 111.6 Volt
So, the voltage in the circuit will be 111.6 volts. I hope it helps you.

If you are doing a USA TEST Prep:

D)  111.6 V
