Answer:
Explanation:
An Ideal Machine is a machine which gives 100 percent efficieny that is entire input energy is converted into output energy.
however this is not possible as some energy is lost due to friction, imperfect components and all. Therefore no machine is Ideal machine.
He needs to measure when he draws the Simpson characters to make sure they are the same time each time he draws them
We determine the rate of a reaction from the given rate law by substituting the given concentrations and the order of the substances. We calculate as follows:
<span>rate = k[A]^m[B]^n
</span><span>rate = (1 x 10^-2) [2]^2 [3]^1
rate = 0.12 M /s
The rate law of a reaction is an expression that is related to the reaction rate. The parameters used are the concentration or the pressure of the reactants in the reaction. An example would be:
</span><span>
A = B + C
The rate law would be:
Rate = k[A] where k is the reaction rate constant and determined by doing experiments</span>
Answer:
A) λ = 548 nm.
B ) 5.474 x 10¹⁴ Hz.
Explanation:
Distance between two slits ( d ) =.044 x 10⁻³
Distance of screen ( D ) = 6.5 m
Fringe width is given by the expression
Fringe width = λ D /d
where λ is wave length of light .
Given fringe width = 8.1 cm
Putting the values in the equation , we have
8.1 x 10⁻² = λ x 6.5 / .044 x 10⁻³
![\lambda = \frac{8.1\times10^{-2}\times.044\times10^{-3}}{6.5}](https://tex.z-dn.net/?f=%5Clambda%20%3D%20%5Cfrac%7B8.1%5Ctimes10%5E%7B-2%7D%5Ctimes.044%5Ctimes10%5E%7B-3%7D%7D%7B6.5%7D)
λ = 548 nm.
Frequency of light = velocity of light / wavelength
3 x 10⁸ / 548 x 10⁻⁹
= 5.474 x 10¹⁴ Hz.
