They both make a thing go faster and slower but the relationship is force.
What is not the ultimate goal of science is to produce unchanging and absolute answers - D. Scientists would like to, however, understand patterns, give explanations for natural events, and even make predictions. And it isn't really the case that they would like to produce unchanging answers.
Answer:
Explanation:
Let the allele for dark color be represented by "D" and the allele for light color be represented by "d"
Also D is dominant over d
Similarly, let the allele for obese trait in mice be represented by "O" and the allele for lean trait in mice be represented by "L"
Obese and lean exhibit incomplete dominance
Genotype of true breeding dark and obese mice be DDOO
Genotype of true-breeding lean and light mice is ddLL
Offspring from F1 cross -
DdOL
F2 cross is between DdOL * DdOL
DO DL dO dL
DO DDOO DDOL DdOO DdOL
DL DDOL DDLL DdOL DdLL
dO DdOO DdOL ddOO ddOL
dL DdOL DdLL ddOL ddLL
dark and intermediate between obese and lean offspring genotype –
2 DDOL, 4 DdOL
So total six out of sixteen offspring are dark and intermediate between obese and lean -
Answer:
1 kg
Explanation:
The container has negligible mass and no heat is loss to the surrounding.
Mass of ice = 0.4kg, initial temperature of ice = -29oC, final temperature of the mixture = 26oC, mass of water (m2) = ?kg, initial temperature of water = 80oC, c ( specific heat capacity of water ) = 4200J/kg.K, Lf = heat of fusion of water = 3.36 × 10^5 J/kg
Using the formula:
Quantity of heat gain by ice = Quantity of heat loss by water
Quantity of heat gain by ice = mass of ice × heat of fusion of ice + mass of water × specific heat capacity of water = (0.4 × 3.36 × 10^ 5) + (0.4 × 4200 × (26- (-29) = 13.44 × 10^4 + 9.24 × 10^ 4 = 22.68 × 10^4 J
Quantity of heat loss by water = m2cΔT
Quantity of heat loss by water = m2 ×4200× (80 - 26) = m(226800)
since heat gain = heat loss
22.68 × 10^4 = 226800 m2
divide both side by 226800
226800 / 226800 = m2
m2 = 1 kg
