Answer:
B. gives one of the most accurate measurements of body fat
Answer:
They are:
1. Height of liquid
2. Density of liquid
3. Acceleration due to gravity
The fluid is incompressible and has extremely little viscosity. Gravity accelerates at a rate of 9.8 m/s2 and follows a path that causes the liquid to go out of the pipe at a speed of 66.35 m/s.
<h3>What is the principle of Bernoulli?</h3>
Bernoulli's principle, which at first looks counterintuitive, describes the link between a fluid's speed and pressure. Bernoulli's principle states that locations in a horizontal flow of fluid will experience lower pressure than locations where the fluid is moving more slowly.
radius at initial end is given as = 0.24/2 = 0.12 m
now radius at end is given as = 0.05/2 = 0.025 m
utilizing the continuity equation:
A₁ V₁ = A₂ V₂
π (0.12)² × 2.88 = π (0.025)² × V₂
V₂ = 66.35 m/s
∴ The calculated exit terminal velocity is 66.35 m/s.

Answer:
Gravity Increases - Mass increases, distance decreases
Gravity Decreaes - Mass decreases, distance increases
Answer:
The acceleration of the rattlesnake, a = 126 m/s²
Explanation:
Given,
The initial velocity of the rattlesnake, u = 1.0 m/s
The final velocity of the rattlesnake, v = 20.0 m/s
The time duration to reach the final velocity, t = 0.15 s
The acceleration of a body defined as the rate of change of velocity by time, or simply the difference of final velocity and initial velocity by time.
The formula for acceleration is
a = (v-u)/t m/s²
Substituting the values in the above equation
a = (20 - 1.0 ) / 0.15
= 126 m/s²
Hence, the acceleration of the rattlesnake is, a = 126 m/s²
