What is the energy put into a machine or device to make it work
Neporo4naja [7]

Answer:

  • <em>The energy put into a machine or device to make it work is named</em> <u>work input.</u>

Explanation:

<em>Machines </em>are devices to perform tasks with less effort or more easily. They can either increase the force applied or change the direction of the force or permit to apply the force at a distance.

The law of conservation of energy states that the energy is neither created nor destroyed, but when the machines do <em>work</em> some energy is dissipated in the form of heat, light or sound, due, mainly to friction.

In consequence, the <em>work output</em> is less than the <em>work input</em>.

A measure of energy use is efficiency. The efficiency is the ratio of the work output to the work input.

          Efficiency=\dfrac{\text{Work done by the machine}}{\text{Work done on the machine}}

The minimum energy needed to eject an electron from a sodium atom is 4.41 x 10-19 j. what is the maximum wavelength of light, in
Minchanka [31]
The energy of an electron as it is ejected from the atom can be calculated from the product of the Planck's constant and the frequency of the light energy. We can calculate the wavelength from the frequency we can calculate. We do as follows:

E = hv
 4.41 x 10-19  = 6.62607004 × 10<span>-34 (v)
v = 6.66x10^14 /s

wavelength = speed of light / frequency
</span>
wavelength = 3x10^8 / 6.66x10^14
wavelength = 4.51x10^-7 m = 450.75 nm

A passenger on a stopped bus notices that rain is falling vertically just outside the window. When the bus moves with constant v
nekit [7.7K]

Answer:

1)0.325

2)6.17\ \rm m/s

Explanation:

<u>Given:</u>

The angle that falling raindrops make with the vertical=18^\circ

Let V_R be the velocity of the raindrops and V_B be the velocity of the bus.

1)

\dfrac{V_R}{V_B}=\tan 18^\circ\\\dfrac{V_R}{V_B}=0.315\\

2)Speed of the raindrops=0.315\times 19

=6.17\ \rm m/s
