The relationship between kinetic energy and speed is

Chemistry

6 0

Answer:

The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.

This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed.

KE = 0.5 • m • v2

where m = mass of object

v = speed of object

That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine.

Sveta_85 [38]
Colligative properties calculations are used for this type of problem. Calculations are as follows:<span>
</span>

<span>ΔT(freezing point)  = (Kf)m
ΔT(freezing point)  = 1.86 °C kg / mol (0.705)
ΔT(freezing point)  = 1.3113 °C

a solution with a transmittance of 0.44 is analyzed in a spectrophotometer with 6% stray light. calculate the absorbance reporte
IgorLugansk [536]

The absorbance reported by the defective instrument was 0.3933.

Absorbance A = - log₁₀ T

Tm = transmittance measured by spectrophotometer

Tm = 0.44

Absorbance reported in this equipment = -log₁₀ (0.44) = 0.35654

True absorbance can be calculated by true transmittance, Tm = T+S(α-T)

S = fraction of stray light = 6%= 6/100 = 0.06

α= 1, ideal case

T = true transmittance of the sample

Tm = T+S(α-T)

now, T= Tm-S/ 1-S = 0.44-0.06/ 1-0.06 = 0.404233

therefore, actual reading measured is A = -log₁₀ T = -log₁₀ (0.404233)

i.e; 0.3933
