Answer: its The ability to do work or cause change. Energy of an object due to its motion.
Explanation:In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.
Answer:
The 59th element is Praseodymium it's symbol is Pr.
Answer:
x = 625 m
Explanation:
To solve this exercise we use the kinematics relations
v² = v₀² - 2 a x
indicate that the train stops therefore its final speed is zero (v = 0)
0 = v₀² - 2a x
x =
let's slow down to the SI system
v₀ = 90 km / h (1000 m / 1km) (1h / 3600 s) = 25 m / s
let's calculate
x =
x = 625 m
We know that frequency is an inverse value of time this implies that time is the inverse value of frequency .
Now since <em>f</em> is <em>40kHz</em><em>,</em><em> </em>we can calculate period or duration for that matter time.
Hope this helps.
