An object keeps the same amount of kinetic energy unless it speeds up or slows down.
Kinetic energy can be calculated for any moving object as long as the objects' mass and speed are known.
The unit used when measuring kinetic energy is called a joule.
Kinetic energy can occur in any direction whether up and down or left to right.
Answer:
From 4.0 moles of hydrogen 2.67 moles of ammonia are produced.
Explanation:
Given data:
Number of moles of hydrogen react = 4.0 mol
Number of moles of ammonia produced = ?
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Now we will compare the moles of hydrogen and ammonia from balance chemical equation.
H₂ : NH₃
3 : 2
4 : 2/3×4 = 2.67 mol
From 4.0 moles of hydrogen 2.67 moles of ammonia are produced.
Answer:
D. 6.25 J
Explanation:
∴ k = 50 N/m
∴ Δx = 0.5 m
⇒ EPE = 1/2*50 N/m*(0.5m)²
⇒ EPE = 6.25 N.m = 6.25 J
Find it on google i’m pretty sure i saw it somewhere so sorry this doesn’t help
