Volume by Displacement. The displacement method (submersion, or dunking method) can be used to accurately measure the volume of the human body and other oddly shaped objects by measuring the volume of fluid displaced when the object is submerged.
The following precautions should be taken very observantly:-
The line of sight must be perpendicular to measuring scale to avoid parallax error. Formation of bubbles inside the cylinder should be completely avoided. Any bubbles within leads to wrong measurements.
Answer:
A. 4.47 m/s
Explanation:
As the ball oscillates, it mechanical energy, aka the total kinetic and elastics energy stays the same. For the ball to be at maximum speed, its elastic energy i 0 and vice versa. When the ball is at rest, its kinetic energy is 0 and its elastic energy is at maximum at 50 cm, or 0.5 m
1500 g = 1.5 kg
Answer:
its false
Explanation:
because if an leaf floats down from a tree it is not considered an object for a free-fall
Calculate the kinetic energy of an 86-kg scooter moving at 18 m/s?
K.E. = (1/2)mv^2
K.E. = (1/2)86 * 18^2
K.E. = (Answer Unit) =====> J
M = 86kg
V = 18 m/s
Significant Figures ======> 6
Answer: ======>
KE = 13932 J
Show work:
1/2 * 86 * 18^2
(1/2)86 * 18^2
Remove Parenthesis:
a = a
1/2 * 86 * 18^2
Multiply Fractions:
a * b/c = a * b/c
= 1 * 86 * 18^2/2
Multiply the numbers:
1 * 86 = 86
18^2 * 86/2
Divide the numbers:
86/2 = 43
18^2 * 43
18^2 = 324
43 * 324
Multiply the numbers:
43 * 324
13932
Therefore, Your answer is KE = 13932 J
Hope that helps!!!! : ) sorry for the long explanation!!!
