Dmitry_Shevchenko [17]

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.

A liquid of density 1288 kg/m3 flows with speed 2.88m/s into a pipe of diameter 0.24 m. The diameter of the pipe decreases to 0.

Tju [1.3M]

Answer:

66.35m/s

Explanation:

Para resolver el ejercicio es necesario la aplicación de las ecuaciones de continuidad, que expresan que

$A_1V_1 =A_2 V_2$

From our given data we can lower than:

$R_i = \frac{0.24}{2} = 0.12m$

$R_f = \frac{0.05}{2} = 0.025m$

So using the continuity equation we have

$A_1V_1 =A_2 V_2$

$V_2 = \frac{A_1V_1}{A_2}$

$V_2 = \frac{(\pi(0.12^2))(2.88)}{(\pi (0.25)^2)}$

$V_2 = 66.35m/s$

Therefore the velocity at the exit end is 66.35m/s

A sample of 2.50 kg of water is held at a temperature of 100°C. How much energy must be added to completely turn the liquid wate

kap26 [50]

Answer:

Explanation:

Since 100C is the boiling temperature for water, for this problem we don't need to calculate the energy needed to get to the boiling point, just the heat or energy needed to vaporize the water to steam at 100C.

The formula for this is q=m(delta)

q is Joules of heat needed to vaporize the water to steam at 100C

m is mass in grams

Delta is in Joules per gram and can be looked up for water at this temperature. Here, it is approximately 2260J/g. This online lecture should help ease understanding: https://cabrillo.instructure.com/courses/10267/modules/items/256219

Therefore...

q=2.5g (2260J/g)= 5650J = 5.65kJ

I do not do Physics tutoring but am happy to answer questions here.

tresset_1 [31]

Complete Question

Two parallel-plate capacitors C1 and C2 are connected in parallel to a 12.0 V battery. Both capacitors have the same plate area of 5.30 cm2 and plate separation of 2.65 mm. However, the first capacitor C1 is filled with air, while the second capacitor C2 is filled with a dielectric that has a dielectric constant of 2.10.
