Look for scientific research about whether these claims are correct or not.
Explanation:
The best thing to do after reading this advertisement is to look for scientific research about whether these claims are correct or not.
It depends on the electricity passed with cold water or hot water it also depends on the structure of the object in gas the current flows faster than solid or liquid
Let u = the vertical speed at launch, m/s
g = 9.8 m/s², acceleration due to gravity.
Part (a)
After 2.4 s, the vertical speed is 10 m/s.
Therefore
(10 m/s) = (v ft/s) - (9.8 m/s²)*(2.4 s)
v = 10 + 9.8*2.4 = 33.52 m/s
Answer: 33.52 m/s upward
Part (b)
After 5.1 s, the vertical speed is
(33.52 m/s) - (9.8 m/s²)*(5.1 s) = -16.46 m/s.
This means that the rock reached the maximum height and began falling downward.
Answer: 16.46 m/s downward
Falling from an airplane.
Acceleration = vf-vi /t
10-22/3=2.6m/s^2
