Explanation:
Answer:
The time interval is 
Explanation:
From the question we are told that
The constant acceleration is 
The displacement is 
According to the second equation of motion we have that
given that the blade started from rest
which is the initial angular velocity is 0
So
=> 
substituting values
=> 
=>
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.
The correct option is D.
Micheal Friday devised a wire which hanged down into a glass vessel that has a bar magnet secured at the bottom. He then filled the glass vessel with Mercury and connected the apparatus to a battery. This sent electricity through the wire, thus creating a magnetic field around it. This field interacted with the field around the magnet and cause the wire to rotate clock wisely.
