What happens to the energy not output by a machine​

Mathematics
1 answer:
Sveta_85 [38]3 years ago
5 0

Answer:

By using the energy conservation law, the input energy must be equivalent to the output energy.  If you measured output energy is lower than your input energy, you have lost that difference of energy either in mechanical inefficiency (friction, heat, etc.) or an energy sink.

Thus, the energy not output by the machine is lost in the process within the machine.

Cheers.

If α and β are the zeroes of the polynomial 2x2 + 3x – 7, then find a polynomial whose zeroes are and .
Drupady [299]

Answer:

\frac{-\sqrt{65} - 3 }{4}, \frac{\sqrt{65} + 3}{4}

Step-by-step explanation:

Since we cannot factor the expression, we must use quadratic formula: x = \frac{-b +/-\sqrt{b^2 - 4ac} }{2a}

Plug in <em>a</em> for 2, <em>b</em> for 3, and <em>c</em> for -7 and you should find your roots.

A swimming pool is a rectangular prism. The pool is 36 feet long and 20 feet wide. What is the total amount of water, in cubic f
Sliva [168]

Answer:

2880\ ft^{3}

Step-by-step explanation:

The computation of the total amount of water needed could be determined by using the volume formula which is shown below:

Volume = L \times W \times D

where

L = length,

W = width,

and D = depth.

Now putting the values to the above formula

Volume = (36\ ft) \times (20\ ft) \times (4\ ft) \\\\= 2880\ ft^{3}                            

Therefore, the  total amount of water needed is 2880\ ft^{3}

We simply applied the above formula

Solve the equation sine Ф=0.6792 for 0°≤Ф≤360
Sergio [31]

Answer:

42.78⁹, 137.22⁹.

Step-by-step explanation:

sine Ф=0.6792

Angle Ф in the first quadrant = 42.78 degrees.

The sine is also positive in the second quadrant so the second solutio is

180 - 42.78

= 137.33 degres.
