The answer should be C
The reason for this is because:
There are 2 "I" on the right side of the equation but only 1 on the left. This means you need to add a 2 on the "KI" to get two "I".
But now there are 2 "K" on the left side and only 1 on the right, meaning you need to add a 2 to the "KCL". This makes it balanced
Kinetic Energy Statement
Kinetic energy is energy that a body possess as a result of its motion. Kinetic energy as it is mathematically written is the "classic statement" of: Kinetic energy is equal to half the mass of an object times its velocity squared.
There are five types of kinetic energy: radiant, thermal, sound, electrical and mechanical. Let us look at some of the kinetic energy examples and learn more about the different types of kinetic energy.

The volume is the space it takes up, which would be the same. The mass is measured as the weight, and the steel ball would be significantly heavier. Density is mass/volume, and if the steel has a larger mass, it will therefore have a higher density.
.07! you divide 7 by 100%
Answer:
The answer to your question is T2 = 610.9 °K
Explanation:
Data
Volume 1 = V1 = 30 cm³
Temperature 1 = T1 = 420 °K
Pressure 1 = P1 = 110 kPa
Volume 2 = V2 = 40 cm³
Temperature 2 = T2 = ?
Pressure 2 = P2 = 120 kPa
Process
To solve this problem use the combined gas law.
P1V1/T1 = P2V2/T2
-Solve for T2
T2 = P2V2T1 / P1V1
-Substitution
T2 = (120 x 40 x 420) / (110 x 30)
-Simplification
T2 = 2016000 / 3300
-Result
T2 = 610.9 °K
