Noting cloudiness occurs when two solutions are mixed.
Answer:
Option (c)
Explanation:
Both the bullets have same acceleration because they both falls under the influence of acceleration due to gravity.
The bullet which is fired from the gun has some initial velocity but the bullet which is dropped has zero initial velocity.
the acceleration is acting on both the bullets which is equal to the acceleration due to gravity and they both in motion in the influence of gravity.
To solve this problem we apply the thermodynamic equations of linear expansion in bodies.
Mathematically the change in the length of a body is subject to the mathematical expression
Where,
Initial Length
Thermal expansion coefficient
Change in temperature
Since we have values in different units we proceed to transform the temperature to degrees Celsius so
The coefficient of thermal expansion given is
The initial length would be,
Replacing we have to,
This means that the building will be 35.5cm taller
The answer is B. On a sunny day, the air over a lake will be cooler than the air over the bordering land.
