Molecules are continuously colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces.The more particles that hit the walls, the higher the pressure.
They will continue moving because an object in motion will stay in motion until acted upon by a new force. I believe this is Newton's Law of Motion.
We can use the magnification equation for this problem.
Magnification equation:
<em>hi/h0 = di/d0</em>
Where in <em>hi </em>: image size, <em>h0</em> : object size, <em>di </em>: image distance, <em>d0 </em>: object distance from mirror
So plugging in the given variables we will have the corresponding equation
0.1 m / 0.3 m = <em>di / </em>0.4 m
<em>di</em> = 0.1333333m
The generated image of the object is located 0.13 meters or 13 cm away from the mirror
Water behaves as a base when it reacts with deprotonated methylamine.
Answer:
E Indium = 4.407 x 10⁻¹⁹ J
E Thallium = 3.716 x 10⁻¹⁹ J
Explanation:
From Planck´s equation for a given wavelength, the energy is given by.
E = h ( c/ λ )
h: Planck´s constant, 6.626 x 10⁻³⁴ J·s
c: light speed, 3 x 10⁸ m/s
λ: wavelength in m
We will need first to convert the given wavelengths to m:
451.1 nm x ( 1 m/10⁹ nm ) = 4.511 x 10⁻⁷ m
535.0 nm x ( 1 m/10⁹ nm ) = 5.350 x 10⁻⁷ m
E Indium = 6.626 x 10⁻³⁴ J·s x 3x 10 ⁸ m/s/ 4.511 x 10⁻⁷ m = 4.407 x 10⁻¹⁹ J
E Thallium = 6.626 x 10⁻³⁴ J·s x 3x 10 ⁸ m/s/ 5.350 x 10⁻⁷ m = 3.716 x 10⁻¹⁹ J
