Hi there!
Recall the equation for weight.
W = Weight (N)
M = Mass (kg)
g = acceleration due to gravity (m/s²)
The weight of an object depends upon its MASS and the strength of the GRAVITATIONAL field. We can solve for weight:
Answer:
1.74 × 10^-3 m ( 1.74 mm)
Explanation:
Using Torricelli"s equation to calculate the speed of water at the surface of the hole and assuming that the speed of water at the surface of the tank is zero
v ( speed of water at the surface of the hole) = √ 2g(h1 - h2) where h1 - h2 is the difference in height which 16 m
v = √ 2×9.81×16 = 17.72 m/s
work done in ( m³/s) = 2.5 × 10^ -3 / 60 seconds = 4.2 × 10^-5 m³/s
work done = A × v
4.2 × 10^-5 = A × 17.72
4.2 × 10^-5 / 17.72 = A
2.37 × 10^-6 = A where A is assumed a circle ( πr²)
r = 2.37 × 10^-6 / π = √2.37 × 10^-6 / 3.142 = 0.869 × 10 ^ -3
diameter = 2r = 2 × 0.869 × 10^-7 = 1.74 × 10^-3 m

Answer:
metal
Explanation:
sound can travel best in materials with higher elastic properties like metal than it can through other solids like plastic or rubber which have lower elastic properties
I hope this helps
