A flexible balloon contains 0.330 mol of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 710

0 cm3 and a temperature of 24.0 ∘C. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as an ideal gas with Cp=33.26J/mol⋅K and γ=4/3.
A. What is the total heat Q supplied to the gas in the process?B. What is the total change in the internal energy ΔU of the gas?C. What is the total work W done by the gas?D. What is the final volume V?

Answer:

Explanation:

The initial temperature is 27+273= 300K.

The volume doubles. V∝T when pressure is constant (isobaric expansion). So the new temperature is 2x300=600K.

There are different ways to do the above step.  E.g. you could say:

P1V1/T1 = P2V2/T

P1V1/300 = P2(2xV1)/T2

V1 cancels and since P1= P2, P1 and P2 cancel

1/300 =  2/T2

T2 = 600K

but this is much more work than using simple proportion.

For the isobaric (constant pressure) expansion, the heat transferred is:

Q = Cp.n.ΔT

= 33.26 x  0.370 x (600 - 300)

= 3692J

= 3690J to 3 significant figures

When the gas expands adiabatically there is no heat transfer (by definition of adiabatc).

So the total heat transfer is 3690J.

The asteroid belt circles the sun between the orbits of Mars and Jupiter. One asteroid has a period of 5.4 earth years.
Ad libitum [116K]

Answer:

(a) Radius = 4.6 x 10^11 m

(b) speed = 16.96 km/s

Explanation:

Time period, T = 5.4 earth years

mass of sun, M = 1.989 x 10^30 kg

(a) Let the orbital radius is R.

use the formula of period

T^2 = \frac{4 \pi^2 R^3}{G M}\\\\\left ( 5.4\times 365\times 24\times 3600 \right )^2 = \frac{4\times3.14\times 3.14\times R^3}{6.67\times10^{-11}\times 1.989\times 10^{30}}\\\\R = 4.6\times 10^{11} m

(b) Let the speed is v.

v=\frac{2 \pi\times R}{T}\\\\v=\frac{2\times 3.14\times 4.6\times 10^{11}}{5.4\times 365\times 24\times 3600}\\\\v = 16963.6 m/s =16.96 km/s

A 12-kg hammer strikes a nail at a velocity of and comes to rest in a time interval of 8.0 ms. (a) What is the impulse given to
koban [17]

Answer:

Impulse = 0.9408Ns

Explanation:

Impulse is the product of force and time

Impulse = Ft

Given

Force F = mg

F = 12(9.8)

F = 117.6N

Time = 8 * 10^-3 = 0.008s

Get the impulse

Impulse = 117.6*0.008

Impulse = 0.9408Ns

A multidimensional database (MDDB) is a type of database in which data can be viewed from multiple dimensions; commonly used with <u>MOLAP</u>.

A multidimensional database affords the ability to swiftly procedure statistics and generates solutions quickly. MDBs let users ask questions about corporations' operations and traits.

The multidimensional databases make use of MOLAP (multidimensional online analytical processing) to get admission to its statistics. They permit the users to fast get answers to their requests by means of generating and analyzing the records as a substitute quickly. The information in multidimensional databases is stored in a records dice format.

In a  dimensional database, you have rows and columns, represented by means of X and Y. In a multidimensional database, you have got X, Y, Z, etc. depending on the number of dimensions in your statistics. Beneath is an instance of a 3-Dimensional statistics Array represented in a relational table and in 3-D.
