By using it for a long time lol.
It means that is it a sugar molecule
Answer:
The maximum potential energy of the child will be maximum at the two end points.
The maximum kinetic energy of the <em>child </em>occurs at the lowest point of the swing.
The potential energy of the child depends on the displacement of the child.
P.E = mgh
The maximum height attained occurs at the two end points of her swing motion.
Thus, the maximum potential energy of the child will be maximum at the two end points.
The kinetic energy of the child depends on the velocity of the child
K.E = ¹/₂mv²
The maximum velocity of the swing occurs at the lowest point of the swing.
Thus, the maximum kinetic energy of the child occurs at the lowest point of the swing.
Hope this helps!
Answer:
Bowling ball
Explanation:
They are traveling at the same speed, but the bowling ball has more mass. The bowling ball has more kinetic energy because more force is needed to stop the rolling bowling ball. Two balls with different masses moving at the same speed have different amounts of kinetic energy.
Since the mole ratio is 1 to 1 for this reaction, you can just use M1V1 = M2V2 to solve, given that 1 refers to HBr and 2 refers to LiOH.
M1 = ?
V1 = 0.40 L
M2 = 0.50 M
V2 = 0.20 L
M1(0.40) = (0.50)(0.20)
Solve for M1 —> M1 = (0.50)(0.20)/0.40 = 0.25 M HBr
