(9) Mechanical advantage = force by machine / force applied to machine
0.6 = 600 / F
F = 1000 N
(2) Efficiency = (output / input) x 100
Efficiency = (500 / 2000) x 100
Efficiency = 25%
(4) The overall energy conversion in power plants is chemical to electrical while in dams it is potential to electrical.
(5) Using the formula:
1568 = 40 x 9.81 x h
h = 4.0 m
(6) Potential to electrical
(10) An object raised and held stationary above the ground.
Energizer due to a chemical that duracell does not have
Answer: The wavelength is
and
of this radiation
Explanation:
To calculate the wavelength of light, we use the equation:
![\lambda=\frac{c}{\nu}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cfrac%7Bc%7D%7B%5Cnu%7D)
where,
= wavelength of the light = ?
c = speed of light = ![3\times 10^8m/s](https://tex.z-dn.net/?f=3%5Ctimes%2010%5E8m%2Fs)
= frequency of light = ![22.235GHz=22.235\times 10^{9}Hz=22.235\times 10^{9}s^{-1}](https://tex.z-dn.net/?f=22.235GHz%3D22.235%5Ctimes%2010%5E%7B9%7DHz%3D22.235%5Ctimes%2010%5E%7B9%7Ds%5E%7B-1%7D)
![\lambda=\frac{3\times 10^8m/s}{22.235\times 10^9s^{-1}}=0.013m](https://tex.z-dn.net/?f=%5Clambda%3D%5Cfrac%7B3%5Ctimes%2010%5E8m%2Fs%7D%7B22.235%5Ctimes%2010%5E9s%5E%7B-1%7D%7D%3D0.013m)
![1m=10^{9}nm](https://tex.z-dn.net/?f=1m%3D10%5E%7B9%7Dnm)
![1m=10^{10}A^0](https://tex.z-dn.net/?f=1m%3D10%5E%7B10%7DA%5E0)
Thus wavelength is
and
of this radiation
Answer:
The mass of 0.100 mole of neon is 2.018 grams.
Explanation:
As we know the formula to find mass:
Number of moles = Mass/ Molar mass
0.100 = Mass/ 20.17
0.100 x 20.17 = Mass
Mass=2.018 grams.
Hope it helps!
Cl, because a higher electronegativity indicates that the atom attracts more electrons.
