Answer:
0.1 m
Explanation:
It is given that,
Mass of the object, m = 350 g = 0.35 kg
Spring constant of the spring, k = 5.2 N/m
Amplitude of the oscillation, A = 10 cm = 0.1 m
Frequency of a spring mass system is given by :
Time period:
From equation of motion v^2 = u^2 +2aS
Hence, the final velocity is 40 m/s.

<span>procedure would most likely help determine a chemical property of the substance is : exposing it to a flame to see if it catches on fire
Chemical property is the characteristic that a substance has that differntiate it with another substance. The most common charatcteristics that most scientists wanted to know are :
- It's flamability
- It's radioactivity
- Its toxicity
By throwing the object into fire, we will easily find out these 3 characteristics</span>
When a snowball turns into a puddle of water, we know that (the snow ball gains energy and changes from a solid to liquid).
This is correct due to the fact that particles of the snowball are gaining speed and so it is heating up, when the solid's temperature reaches the melting point, it will become a liquid.
Therefore, D is the correct answer.
Given:
heat generated by John's cooling system,
= 45 W (1)
If ρ, A, and v corresponds to John's cooling system then let
be the variables for Mike's system then:



Formula use:
Heat generated, 
where,
= density
A = area
v = velocity
Solution:
for Mike's cooling system:
=
⇒
=
× A ×
= 4.513
A 
Using eqn (1) in the above eqn, we get:
= 4.513 × 45 = 203.09 W
