Answer:
Explanation:
Distance between proton and electron = r = 5.5 x 10⁻¹³ m
Magnitude of charge on electron and proton = 1.67 x 10⁻¹⁹ C
To find their initial acceleration first force between them is:
Initial acceleration of electron and proton are found using
F=ma
a=F/m
Your answer is.......... That's because Earth is a solid mass and the Sun is gaseous.
Answer:
Conduction occurs when two objects at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature. ... It is caused by the increased activity or speed of molecules in a substance, which in turn causes temperature to rise accordingly. This process continues until heat energy from the warmer object spreads throughout the cooler object.

Answer:
λ = 6 10⁻⁷ m
Explanation:
This problem is a double slit interference spectrum where bright maxima are described by constructive interference.
d sin θ = m λ
Where d is the gap of the slits (d = 0.2 10⁻³ m), m is the maximum interference and λ is the wavelength
We used trigonometry to find the angle
tan θ = y / x
Since the angles in these experiments are very small we use
tan θ = sin θ / cos θ = sin θ
sin θ = y / x
We substitute
d y / x = m λ
λ = d y / m x
In this case the first maximum is m = 1
We substitute
λ = 0.2 10⁻³ 3.6 10⁻³ / (1 1.2)
λ = 6 10⁻⁷ m
The approximation made in this problem is that since the angles are small we approximate the tangent to the sine
