Answer:
The wavelength is 754.2 nm.
Explanation:
Given that,
Diffraction pattern y= 1.35 mm
Width = 0.838 mm
Distance D= 75 cm
We need to calculate the wavelength
Using formula of diffraction pattern


Where, y = diffraction pattern
m = order
d = width
D = distance
Put the value into the formula



Hence, The wavelength is 754.2 nm.
(C). Remember gravity provides an acceleration of 9.81m/s^2, so the y component of velocity initial is zero because it isn’t already falling, and we have the height, so basically we use the kinematic equation vf^2=vi^2+2ad, substitute given values and you get vf^2=2(9.81)(65) which is 1275, when you take the square root you get 35.7m/s for final velocity
(B). Then you use vf=vi+at to get the equation 35.7=(9.81)t, when you divide out you get 3.64s for time t
(A). Finally, since we assume that there is no acceleration or deceleration horizonatally, we just multiply the time taken for it to hit the ground and the initial speed ((3.64)(35.7)) to get 129.96, with significant figures I would round that to 130 metres.
**this is in the order that I felt was easiest to answer**
Gold is much heavier because it has a greater density, meaning the atoms are more closely packed. Also, the individual atoms are heavy as well making 1g of gold heavier than 1g of aluminum.
When the experimental measurements diverge at very low values of the voltages. When the ratio of current to saturated current is very small. That is, i/I less than or equal to 1/100. When there is a finite current at Voltage
V = 0
Diffusion will have influence on current - voltage curve in the working electrode which is ionization detector.
The estimation under set of conditions that is possible, despite the spherical shape of the working electrode, to use linear diffusion equations to theoretically predict the current vs voltage curve expected in this experiment will be:
- When the experimental measurements diverge at very low values of the voltages
- when the ratio of current to saturated current is very small. That is, i/I less than or equal to 1/100
- When there is a finite current at Voltage V = 0
Where
i = electric current
I = saturated current
V = voltage supplied
The curve expected will therefore give exponential curve from positive to negative domain because of the diffusion of ions from different directions
