A moon orbits a planet every 42 hours with a mean orbital radius of .002819 AU. The mass of the moon is 8.932 x 1022 kg. Using N

Pepsi [2]

Answer:

The mass of the planet is $1.9407\times10^{27}\ kg$

Explanation:

Given that,

Time period = 42 hours = 151200 sec

Orbital radius = 0.002819 AU = 421716397.5 m

Mass of moon $m=8.932\times10^{22}\ kg$

We need to calculate the mass of the planet

Using Kepler’s third law

$T^2\propto a^3$

$T^2=\dfrac{4\pi^2}{G(M+m)}\times a^3$

Where, a = orbital radius

T = time period

G = gravitational constant

M = mass of moon

m = mass of planet

Put the value into the formula

$(151200)^2=\dfrac{4\pi^2}{6.673\times10^{-11}(8.932\times10^{22}+m)}\times(421716397.5)^3$

$(8.932\times10^{22}+m)=\dfrac{4\pi^2}{6.673\times10^{-11}}\times\dfrac{(421716397.5)^3}{(151200)^2}$

$(8.932\times10^{22}+m)=1.94087\times10^{27}$

$m=1.94087\times10^{27}-8.932\times10^{22}$

$m=1.9407\times10^{27}\ kg$

Hence, The mass of the planet is $1.9407\times10^{27}\ kg$

Answer ?

morpeh [17]

Answer:

2.75 m/s^2

Explanation:

The airplane's acceleration on the runway was 2.75 m/s^2

We can find the acceleration by using the equation: a = (v-u)/t

where a is acceleration, v is final velocity, u is initial velocity, and t is time.

In this case, v is 71 m/s, u is 0 m/s, and t is 26.1 s Therefore: a = (71-0)/26.1

a = 2.75 m/s^2

What are the requirements for chemical labels

yaroslaw [1]

A chemical label should include: a product identifier, signal word, hazard statement, precautionary statement,pictorgrams and supplier information

Explanation:

The product identifier : positioned at the upper left end corner of the label gives the identity of the hazardous chemical by appropriate terms. i.e. the name and code

Signal word: The "Danger" and "WARNING" words. The former is used for a more severe hazard where as the former is for a less severe hazard

Hazard statement : gives a description of the nature and degree of hazard of the chemical

Precautionary statements : Put for workers and users on ways to minimize exposure and lower risks in event of contact with the harmful chemical

Supplier information : It has the chemical manufacturer details such as name, location and telephone number.

Pictograms : Normally symbols with red borders for visual illustration of the hazard chemical.
