Three cubes, of side l0, 2l0 ,and 3l0 are placed next to one another (in contact)with their centers along a straight line as shown in thefigure.What is the position, along this line, of the CM ofthis system? Assume the cubes are made of the same uniformmaterial. Express your answer in terms of l0. Expressyour answer using TWO significant figures. - 360 Ο = x XCM = from the left edge of the smallest cube.

A core-collapse supernova explodes at redshift z = 0.4. The laboratory Balmer beta line wavelength is 486.13 nm. The absorption component of the Balmer beta P-Cygni profile is at 490 nm. What is the velocity of the hydrogen material? This time, a core-collapse supernova explodes in the Small Magellanic Cloud, leaving a neutron star as the central remnant. What emission can we observe from the supernova (note different mechanisms/parts will emit at different wavelengths and evolutionary stages)? What of the telescopes mentioned in class would you use to collect such data?

The radius of a sphere was measured to be 20 cm with a possible error of 0.5 cm. (a) Use differentials to estimate the maximum error in the calculated surface area. (Round your answer to the nearest integer. The surface area of a sphere is S=4πr2.) ___ cm2 What is the relative error? (Round your answer to three decimal places.) (b) Use differentials to estimate the maximum error in the calculated volume. (Round your answer to the nearest integer. The volume of a sphere is V=4/3πr3.) ___ cm3 What is the relative error? (Round your answer to three decimal places.)

4. Consider the determinant as a sum of signed products. Recall that there are \( n \) ! elementary products in the determinant expansion of an arbitrary \( n \times n \) matrix \( A \). (a) If \( A \) is a \( 5 \times 5 \) matrix, how many of the elementary products in \( \operatorname{det}(A) \) are guaranteed to be zero if the entry \( a_{12} \) is zero? (b) If \( A \) is an \( n \times n \) matrix, \( n \geq 2 \), how many of the elementary products in \( \operatorname{det}(A) \) are guaranteed to be zero if \( a_{12}=0 \) ? Give your answer in terms of \( n \). (c) If \( A \) is an \( n \times n \) matrix with \( \operatorname{det}(A) \neq 0 \), what is the maximum possible number of zero entries in A? Give your answer in terms of \( n \).
