Answer:
Lack of proper roof ventilation
Explanation:
The icicles hanging off the eaves of a roof are due to lack of proper roof ventilation. This means after snowfalls the attic of the roof receives warm air which melts the snow above. This is caused because the upper part of roof is above 32⁰C (which melts the snow) and lower part of your roof is at a lower temperature which refreezes the snow dripping down to form icicles.
That statement is impossible to show, demonstrate, or prove.
A big part of the reason for the inability to show it is that the statement is ... prima facie, pro bono, and habeus corpus ... wrong, and as false as the day is long.
Although I am certainly far from what you might call a 'particle', I think I can show, using myself, that the statement is false:
As we speak, I am sitting, <u><em>in a stationary state</em></u>, before my computer. It is my intention, and I fully believe it will come to pass, that in a few seconds, my fingers may move to operate one of the letter keys, or my hand may reach out to snag my coffee cup, or my entire being may arise from my place and go into the kitchen for a bowl of oatmeal. At the INSTANT that any of these events takes place, the statement will have been proven false.

The equation of the graph is
Force = (mass) x (acceleration) .
The graph is a straight line that passes through the origin,
and its slope is the mass of the object being studied.
Answer:
10 m/s
Explanation:
Given:
Amplitude of atomic vibrations (λ) = 10⁻⁹ cm = 10⁻⁹ × 10⁻² m = 10⁻¹¹ m [1 cm = 10⁻² m]
Frequency of the vibrations (f) = 10¹² Hz
In order to find the atom's maximum speed, we need to make use of the formula that relates speed, frequency and wavelength of the vibration.
Therefore, the formula for maximum speed is given as:
Now, plug in the values given and solve for speed 'v'. This gives,
Therefore, the atom's maximum speed due to thermal energy provided is 10 m/s.
