Answer: Option A: 22.5 m
Explanation:
A stone is dropped from a tower. The initial velocity of the stone, u = 0.
Height of the tower, y = 100 m
Let the depth of the well be d.
Time taken of the drop of the stone, t = 5 s
The stone falls under acceleration due to gravity g = 9.81 m/s²
We will use second equation of motion:
s = u t + 0.5 g t²
⇒100 m + d = 0 + 0.5 × 9.81 m/s²× (5.00 s)²
⇒d = (122.6 - 100) m = 22.6 m ≅ 22.5 m
Thus, the correct option is A. The depth of the well is 22.5 m.
The heat gun<span> obviously wins this round. Master Appliance </span>heat guns<span> can reach temperatures of up to 1,000 Fahrenheit. A handheld </span>blow dryer<span> might reach 131 degrees Fahrenheit. A </span>hair dryer<span> gets hot enough to burn skin, but not hot enough to complete serious tasks like striping paint and removing serious. By the way I got this from google.</span>

The answer is A. Cameras that use photographic film.
Light has both properties of a wave and a particle.<span>Light can be treated like a wave, but its energy is distributed in discrete packets called </span>photons. Light can appear in different wavelength -- the greater the wavelength, the lesser energy it emits. This explains the existence of color! A <span>chemical change occurs in the photographic detectors that are coated on the film when the energy in the photon of light hits the film. This process is called photochemistry. </span>
Answer:
The new temperature is 
Explanation:
From the question we are told that
The coefficient of linear expansion is 
The temperature is 
The radius of the frames is 
The new radius is 
The change in radius is mathematically represented as
substituting values
The increase in radius can also be mathematically represented as
Where 
is the the new temperature , making it the subject we have
substituting value
