Use the law of conservation of energy to explain why the work output of a machine can never exceed the work input

Veronika [31]3 years ago

The law of conservation of energy states that energy is not created nor destroyed, rather it is only transferred or transmitted from one form to another. Now, the work exerted which is the input is only transformed to move the object which is now becomes the output work. Some are used to move the object, some are converted to other forms. That is why it is never greater than the input energy. Thank you for your question. Please don't hesitate to ask in Brainly your queries.

Answer:

Explanation:

According to the law of energy conservation- energy of a closed system can neither be created nor be destroyed it can be only transformed. In a machine we get supply of input which get converted into different forms, we can not create any additional energy as input so it is possible that all the input energy converts into output( extreme case, when losses are zero) otherwise input energy coverts into many other form(heat, friction,etc) in the process of generating output. So output of a machine can never exceeds the input.

What has to happen for a feather and ball to fall at the same time
Alex_Xolod [135]
This means that two objects will reach the ground at the same time if they are dropped simultaneously from the same height. ... When air resistance plays a role, the shape of the object becomes important. In air, a feather and a ball do not fall at the same rate.

Cuál es la resistencia de un foco que está conectado a una fuente de 20 v por el cuál pasa una intensidad de 20 mA
LUCKY_DIMON [66]

Answer:

The resistance of the bulb is 1000 ohms.

Explanation:

What is the resistance of a bulb that is connected to a 20 v source through which a current of 20 mA passes

We have,

Voltage of the bulb is 20 V and the current passes is 20 mA.

It is required to find the resistance of the bulb. The relation between resistance, current and voltage is given by using Ohm's law as :

V =  IR

R is resistance

R=\dfrac{V}{I}\\\\R=\dfrac{20}{20\times 10^{-3}}\\\\R=1000\ \Omega

So, the resistance of the bulb is 1000 ohms.
