A string with linear density 0.500 g/m.
Tension 20.0 N.
The maximum speed 
The energy contained in a section of string 3.00 m long as a function of .
We are given following data for string with linear density held under tension :
μ = 0.5 
= 0.5 x 10⁻³ 
T = 20 N
If string is L = 3m long, total energy as a function of is given by:
E = 1/2 x μ x L x ω² x A²
= 1/2 x μ x L x 
= 7.5 x 10⁻⁴
So, The total energy as a function of = 7.5 x 10⁻⁴

Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it ha
Answer:
B) 89500 km
Explanation:
speed = distance / time
time= 3h 58 min = 30+58/60= 30.966 h = 31 hrs (approxx)
250= distance / 31
250× 31= distance
distance = 7750 ( approxx)
but none of the given options is 7750 km so we will choose the answer nearest to it,
therefore 89500km is the right answer
Answer:
Buoyant Force: Cause and Calculation
The result is a net upward force (a buoyant force) on any object in any fluid. If the buoyant force is greater than the object's weight, the object will rise to the surface and float. If the buoyant force is less than the object's weight, the object will sink.
We first calculate the acceleration on the ball using:
2as = v² - u²; u = 0 because ball is initially at rest
a = (36)²/(2 x 0.35)
a = 1850 m/s²
F = ma
F = 0.058 x 1850
= 107.3 Newtons
