A modern statement of Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion. ... The equation shows that, as absolute temperature increases, the volume of the gas also increases in proportion.

i hope it will help

You are the science officer on a visit to a distant solar system. Prior to landing on a planet you measure its diameter to be 1.

babymother [125]

Answer:

Mass of the planet = 1.48 × 10²⁵ Kg

Mass of the star = 5.09 × 10³⁰ kg

Explanation:

Given;

Diameter = 1.8 × 10⁷ m

Therefore,

Radius = $\frac{\textup{Diameter}}{\textup{2}}$ = $\frac{\textup{1.8}\times10^7}{\textup{2}}$

or

Radius of the planet = 0.9 × 10⁷ m

Rotation period = 22.3 hours

Radius of star = 2.2 × 10¹¹ m

Orbit period = 407 earth days = 407 × 24 × 60 × 60 seconds = 35164800 s

free-fall acceleration = 12.2 m/s²

Now,

we have the relation

g = $\frac{\textup{GM}}{\textup{R}^2}$

g is the free fall acceleration

G is the gravitational force constant

M is the mass of the planet

on substituting the respective values, we get

12.2 = $\frac{6.67\times10^{-11}\times M}{(0.9\times10^7)^2}$

or

M = 1.48 × 10²⁵ Kg

From the Kepler's law we have

T² = $\frac{\textup{4}\pi^2}{\textup{G}M_{star}}(R_{star})^3$

on substituting the respective values, we get

35164800² = $\frac{\textup{4}\pi^2}{6.67\times10^{-11}\timesM_{star}}(2.2\times10^{11})^3$

or

$M_{star}$ = 5.09 × 10³⁰ kg

A (light) pallet has a load of cases of tomato paste each of which is a cube of length L and has identical mass. Find the center

Dafna1 [17]

Answer:

From left = 1.2L

From back = 0.9L

Explanation:

5 x = 3(L-X) + 2(2L-X)

X = 0.7L

Distance from left = 1.2L

7y = 2(L-X)+1(2L-x)

Y = 0.4L

Distance from back = 0.9L

Mars2501 [29]

Answer:

a) $a=5.7551 \times g$

b) $d=20.5539\times g$

Explanation:

Given:

speed of rocket initially, $v_i=0\ m.s^{-1}$

top speed of rocket after acceleration, $v=282\ m.s^{-1}$

time taken to get to the top speed, $t_i=5\ m.s^{-1}$

final speed of the rocket, $v_f=0\ m.s^{-1}$

time taken to get to the final speed after reaching the top speed, $t_f=1.4\ s$

Now the acceleration:

$a=\frac{v-v_i}{t_i}$

$a=\frac{282-0}{5}$

$a=56.4\ m.s^{-2}$

Now as a fraction of gravity:

$a=\frac{56.4}{9.8}\times g$

$a=5.7551 \times g$

Now, the deceleration:

$d=\frac{0-282}{1.4}$

$d=201.4285\ m.s^{-2}$

Now as a fraction of gravity:

$d=\frac{201.4285}{9.8}\times g$

$d=20.5539\times g$
