Answer:
0.441 L
Explanation:
At constant pressure, Using Charle's law :-
Given ,
V₁ = 0.500 L
V₂ = ?
T₁ = 25.0 °C
T₂ = -10.0 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (25 + 273.15) K = 298.15 K
T₂ = (-10 + 273.15) K = 263.15 K
Using above equation as:
<u>New volume = 0.441 L</u>
Answer:
velocity = 29925×10⁶ m/s
Explanation:
Given data:
Frequency = 35 MHz
Wavelength = 855 m
Velocity = ?
Solution:
MHz to Hz
35×10⁶ Hz
Formula:
<em>velocity = Wavelength × Frequency</em>
velocity = 855 m × 35×10⁶ Hz
velocity = 29925×10⁶ m/s
Hz = s⁻¹
Basically, this figure represents scattering of alpha particles by the atoms of a gold foil.
- Here, A represents that a few alpha particles are deflected through large angle. It shows that the nucleus of the atom is positively charged which repels the positively charged alpha particles and deflect them from their original path.
- B represents that most alpha particles pass straight through the gold foil without any deflection from their original path. The reason is that there is a lot of empty space in the atom.
- C represents that some alpha particles are deflected through small angles. The reason is same as that of A.

12736 would be the number too the 100
