Which of the following positions would Earth be in if it were winter in the Northern Hemisphere?

abruzzese [7]

Answer:

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

After three half-lives, one-ninth of an original radioactive parent isotope remains, and eight-ninths has decayed into the daugh

BartSMP [9]

Answer:

B. False

The true statement will be:

After three half-lives, one-eighth of an original radioactive parent isotope remains, and seven-eighth has decayed into daughter isotopes.

Explanation:

Half life means the time after which the amount of the given substance becomes half of its initial amount, by radiation.

Thus after each successive half life the material is halved or half of it is decayed, which leads to a general formula:

Remaining Amount = 1/2^n of parent isotope

where, n is the number of half lives passed. So, for three half-lives:

Remaining Amount = 1/2^3 of parent isotope

Remaining Amount = 1/8 of parent isotope

Thus, the decayed amount will be:

Decayed Amount = (1-1/8) of parent isotope

Decayed Amount = 7/8 of parent isotope

Thus, the given statement is B.False

At which temperature do the lattice and conduction electron contributions to the specific heat of Copper become equal.

sp2606 [1]

Answer:

At 3.86K

Explanation:

The following data are obtained from a straight line graph of C/T plotted against T2, where C is the measured heat capacity and T is the temperature:

gradient = 0.0469 mJ mol−1 K−4 vertical intercept = 0.7 mJ mol−1 K−2

Since the graph of C/T against T2 is a straight line, the are related by the straight line equation: C /T =γ+AT². Multiplying by T, we get C =γT +AT³ The electronic contribution is linear in T, so it would be given by the first term: Ce =γT. The lattice (phonon) contribution is proportional to T³, so it would be the second term: Cph =AT³. When they become equal, we can solve these 2 equations for T. This gives: T = √γ A .

We can find γ and A from the graph. Returning to the straight line equation C /T =γ+AT². we can see that γ would be the vertical intercept, and A would be the gradient. These 2 values are given. Substituting, we f ind: T =

√0.7/ 0.0469 = 3.86K.

A piece of wood is has a density of 0.6 g/cm3. when dipped in olive oil of density 0.8 g/cm3, what fraction of the wood is subme

Debora [2.8K]

A piece of wood is has a density of 0.6 g/cm3. when dipped in olive oil of density 0.8 g/cm3, 0.75 fractions of the wood is submerged inside the oil.

Fractions describe any number of parts of a whole, or more generally equal parts.In everyday English, fractions describe how many parts of a particular size there are. 8, 3/4.

In mathematics, fractions are used to represent proportions/parts of a whole. represent the same part of the whole. A fraction has two parts, a numerator and a denominator. The top number is called the numerator and the bottom number is called the denominator. A fraction is a part of a whole number and a way of dividing a number into equal parts. It is described as the number of equal parts counted (called the numerator) to the number of whole parts called the denominator. These numbers are separated by dashes.
