The mass, m, of the gas amounts to 0.2504 grams. Explanation: First, we need to calculate the cylindrical tube's volume. The formula for the volume of a cylinder is given by; where V indicates volume, π signifies pi, r represents the radius, and h indicates height or length. Given the following parameters: Radius, r = 1.5 cm, Length, h = 14.4 cm, Density, d = 0.00123 g/cm³. Plugging these into the equation, the volume of the cylindrical tube calculates to be 203.6016 cm³. Density can be defined as mass divided by the volume of an object. Simply put, density is mass per unit volume. Mathematically, density is represented by the formula; by substituting into the equation, we conclude that Mass = 0.2504 g.
Answer:
The runner's deceleration is -23.33 
Given:
Initial speed = 3.5 
Final speed = 0
Time taken = 0.15 s
To determine:
Deceleration of the runner =?
Used Formula:
Using the first equation of motion,
v = u + at
Where, v = final speed
u = initial speed
a = deceleration
t = duration
Solution:
<pusing the="" first="" equation="" of="" motion="">
v = u + at
Where, v = final speed
u = initial speed
a = deceleration
t = duration
0 = 3.5 + a (0.15)
-3.5 = 0.15 (a)
a = 
a = -23.33
The negative sign indicates that this represents deceleration.
Hence, the deceleration of the runner is -23.33

Answer:
If the starting and ending points are identical, the overall work equals zero.
Explanation:
Option (D) is correct.
A force is considered conservative when the work performed by it while moving an object from point A to point B does not rely on the path taken and remains consistent across all paths. The work done is determined solely by the initial and final locations of the particle. Thus, when the initial and final positions in a conservative field coincide, the work is said to be zero.

The focal length of the lens while in water is noted to be 150 cm, whereas in air, it measures 60 cm. To derive these values, the formula incorporates the variations in the refractive index of glass compared to that of the surrounding medium.
