The defining equation for calorimetry is __________.

2 answers:

8 0

The science or act of measuring modifications in state variables of a body for the aim of obtaining the heat transfer related to the modifications of its state due is known as calorimetry. The calorimetry is conducted with the help of calorimeter.

Calorimetry is fundamentally the science related to the exchange of heat with the surroundings. Therefore, the defining equation of calorimetry will be ΔQ1 +ΔQ2 = 0.

Answer:

Q=m.c.ΔT

Explanation:

Calorimetry is the part of physics that studies the phenomena related to thermal energy exchanges. This energy in transit is called heat and occurs due to the temperature difference between the bodies.

Calorimetry can be defined by the equation: Q = m.c.ΔT

Q: Sensitive heat amount (J or lime)
m: body mass (kg or g)
c: specific heat (J / kg ° C or cal / g ° C)
ΔT: temperature range (° C), ie final temperature minus initial temperature

Phenylketonuria (PKU) is a disease caused by a recessive mutation. PKU is extremely common in Ireland, affecting approximately 1

aleksklad [387]

Answer:

97%

Explanation:

PKU is caused by a recessive mutation, which means that affected individuals are homozygous and recessive (tt).

The frequency of genotypes according to Hardy-Weinberg equilibrium is:

$TT= p^2\\Tt=2pq\\tt=q^2$

where p is the frequency of the T allele and q is the frequency of the t allele.

Affected individuals are 1 in 4500, which means the frequency of tt genotype is 1/4500.

If the population is in Hardy-Weinberg equilibrium,

$q^2=1/4500\\q=\sqrt{1/4500} \\\\q=0.015$

The sum of the allele frequencies adds up to 1, therefore:

p + q = 1

p= 1 - q

p= 1 - 0.015

p= 0.985

The frequency of the TT genotype (homozygous wild-type individuals) will be:

$p^2=0.985^2\\p^2=0.97$

97% of the population will have the homozygous wild-type TT genotype.

Answer:

To answer this question, narrow the passage down to a cause and effect scenario, or a simple chain of events.

1. Lisa and her mom get along > 2. Lisa separates from her mother > 3. The mother works to repair their relationship

This can then be shortened to:

Lisa seeks independence > Her mother rebuilds their connection

Of the answers you listed, this most fits the "autonomy versus connection" dynamic.
