Find out what the substance is
<span>Genes, DNA, chromosomes, nucleus</span>
Answer:
α = π/3
β = π/6
Explanation:
Use arc length equation to find the sum of the angles.
s = rθ
π/20 m = (0.1 m) (α + β)
π/2 = α + β
Draw a free body diagram for each sphere. Both spheres have three forces acting on them:
Weight force mg pulling down,
Normal force N pushing perpendicular to the surface,
and tension force T pulling tangential to the surface.
Sum of forces on A in the tangential direction:
∑F = ma
T − m₁g sin α = 0
T = m₁g sin α
Sum of forces on B in the tangential direction:
∑F = ma
T − m₂g sin β = 0
T = m₂g sin β
Substituting:
m₁g sin α = m₂g sin β
m₁ sin α = m₂ sin β
(1 kg) sin α = (√3 kg) sin (π/2 − α)
1 sin α = √3 cos α
tan α = √3
α = π/3
β = π/6
Answer:
Here, he is able both to share his own suffering and—in a way that Mammy cannot—insist on his love for Laila. Babi's dream for leaving Afghanistan is, ironically, based in his love for the country—a love he thinks can be better kept alive by continuing to celebrate its culture and cuisine abroad.JThe nucleus of some isotopes will spontaneously undergo nuclear decay. These isotopes are said to be radioactive. What causes the nucleus of an isotope to be radioactive?
The electric force and nuclear forces are in opposition to each other
Nuclear forces disintegrate protons
There are too many electrons in its orbitals
The electric force causes electrons to be released
(please help i genuinely cant find out why)Babi had wanted Laila and Tariq to understand their country's living, breathing heritage—a heritage quite apart from the violence and turmoil of the national wars. The Buddhas, testimony to an ancient community of monks that lived in caves within the cliffs, symbolize the cultural richness of this national heritageAs an unstable atom tries to reach a stable form, energy and matter are released from the nucleus. This spontaneous change in the nucleus is called radioactive decay. When there is a change in the nucleus and one element changes into another, it is called transmutation.Carbon-14 is unstable and undergoes radioactive decay with a half-life of about 5,730 years (meaning that half of the material will be gone after 5,730 years). This decay means the amount of carbon-14 in an object serves as a clock, showing the object's age in a process called “carbon dating.”Nuclear decay occurs when the nucleus of an atom is unstable and spontaneously emits energy in the form of radiation. The result is that the nucleus changes into the nucleus of one or more other elements. These daughter nuclei have a lower mass and are more stable (lower in energy) than the parent nucleus.
Healthy pregnant women should get at least 150 minutes of moderate-intensity aerobic activity, spread over a 7-day period, each week - True
<u>Explanation:</u>
Women who are healthy but moderately active must be engaged with aerobic activities moderately. they should be engaged with this activities at least 2 and a half hours in all 7 days of a week. They must be engaged with this activity during the pregnancy time and also in the period after their delivery.
During the time of pregnancy all women must be healthy and physically active. The ways for maintaining a very good health in the pregnancy time will be guided by the health care providers. Women should be highly active during and after pregnancy time. This helps in having a baby that is also very healthy.
