Bob is moving at 0.967c with respect to Alice. At the exact instant he passes Alice, she fires a very short laser pulse in the s

yulyashka [42]

Explanation:

Speed of Bob, v = 0.967 c

At the exact instant he passes Alice, she fires a very short laser pulse in the same direction Bob is moving.

(a) We need to find the distance measured by Alice between Bob and the laser pulse. It is given by :

$d=ct-vt$

$d=t(c-v)$

$d=5.59\times (c-0.967c)$

$d=5.53\times 10^7\ meters$

(b) Distance measured by Bob between himself and the laser pulse is given by :

$d_B=ct$

$d_B=3\times 10^8\times 5.59$

$d_B=6.67\times 10^9\ meters$

Hence, this is the required solution.

Calculate the total rotational kinetic energy of the molecules in 1.00 mol of a diatomic gas at 300 K.

AURORKA [14]

Answer:

= 2.49 × 10³J

Explanation:

Total rotational kinetic energy K = nRT

R = 8.134 J/mol.K

n = 1 mol

T = 300 K

K = 1 × 8.314 × 300

= 2.49 × 10³J

Hilda plans to display in a clear cube the needle betsy ross used to sew the first american flag. the needle will fit exactly as

inysia [295]

Based on the length of side of the cube given, the length of the needle is 2.28 inches.

<h3>What is the length of the needle?</h3>

The length of the side of a cube and its diagonal are related by the formula below:

$Length \: of \: Diagonal = \sqrt{3s}$

where s is length of side

$Side \: Length \: of \: the \: Cube = \sqrt{3inches}$

$Diagonal \: of \: a \: face \: of \: the \: cube = \sqrt{6inches}$

$The \: length \: of \: the \: needle = \sqrt{3\sqrt{3}} = 2.28 \: inches \\$

Therefore, the length of the needle is 2.28 inches
