Answer:
50m/s
Explanation:
The formula for calculating speed of wave in relation to frequency and wavelength is
C=λf
Where c is the speed of the wag
λ is the wavelength which is 1m
f is the frequency which is 50Hz
From the formulas,
C= 50X1
C= 50m/s
Rutherford's experiment was done to prove Thompson's Plum Pudding Model. In this model, the protons and electrons are both inside the nucleus. The atoms is neutral because the charges cancel out. Rutherford's hypothesis was that, when a beam of cathode rays hits the gold foil, all the light should pass through. If the Plum Pudding model was correct, that would have been the result. However, it wasn't.
Answer:
Theoretical yield of vanadium = 1.6 moles
Explanation:
Moles of 
= 1.0 moles
Moles of 
= 4.0 moles
According to the given reaction:-
1 mole of react with 5 moles of
Moles of Ca available = 4.0 moles
Limiting reagent is the one which is present in small amount. Thus, Ca is limiting reagent. (4.0 < 5)
The formation of the product is governed by the limiting reagent. So,
5 moles of Ca on reaction forms 2 moles of V
1 mole of Ca on reaction for 2/5 mole of V
4.0 mole of Ca on reaction for 
mole of V
Moles of V = 1.6 moles
<u>Theoretical yield of vanadium = 1.6 moles</u>
Answer:
The Answer is A
Explanation:
particles in gas much like any other particles vibrate. but gas is moving constantly so the answer would be A
Remember the order, <n, l, ml, and ms>.
n: energy level
l: subshell
ml: number of orbitals in the subshell.
ms: electron spin.
The first numbers (n) of both the electrons are the same, but the only difference is the second number (l). The first electron has l=2, indicating that the electron is in the "d" subshell. On the other hand, the second electron has l=1, indicating that the electron is in the "p" subshell.
*Remember*
l=0 (s) spherical shape
l=1 (p) peanut shaped
l=2 (d) clover
