Because mass does not change from place to place but weight does change from place to place... why? because weight is the amount of gravitational force on an object and mass is the amount of matter in an object. mars has less gravitational force so an object will weigh less than it really weighs there

A tin can has a volume of 1100 cm³ and a mass of 80 g. Approximately how many grams of lead shot can it carry without sinking in
Kruka [31]

Answer:

1020g

Explanation:

Volume of can=1100cm^3=1100\times 10^{-6}m^3

1cm^3=10^{-6}m^3

Mass of can=80g=\frac{80}{1000}=0.08kg

1Kg=1000g

Density of lead=11.4g/cm^3=11.4\times 10^{3}=11400kg/m^3

By using 1g/cm^3=10^3kg/m^3

We have to find the mass of lead which shot can it carry without sinking in water.

Before sinking the can  and lead inside it they are floating in the water.

Buoyancy force =F_b=Weight of can+weight of lead

\rho_wV_cg=m_cg+m_lg

Where \rho_w=10^3kg/m^3=Density of water

m_c=Mass of can

m_l=Mass of lead

V_c=Volume of can

Substitute the values then we get

1000\times 1100\times 10^{-6}=0.08+m_l

1.1-0.08=m_l

m_l=1.02 kg=1.02\times 1000=1020g

1 kg=1000g

Hence, 1020 grams of lead shot can it carry without sinking water.

Which shows the formula for converting from kelvins to degrees Celsius? °C = (9/5 × K) +32 °C = 5/9 × (K – 32) °C = K – 273 °C =
madam [21]

The freezing point of the water is 0 C , and it equals to 273 K

Then, To convert from Kelvins degrees to Celsius degrees we use the relation

K = C + 273

Also,

C = K - 273

Identify the person who made the correct statement.
dmitriy555 [2]
The answer is:  [C]:  Neither Juan nor Christina are correct.
_________________________________________________
Explanation:
_____________
Consider Juan's statement:
_______________________
"Juan said fossils deposits always contain only one type of organism."
__________________________
This statement is incorrect.  There are many instances of fossil deposits containing more than one type of organism.
___________________________________
Consider Christina's statement.
___________________________________
"Christina said fossil deposits never contain one type of organism."
___________________________________________
This statement is incorrect.  Fossil deposits, by definition (of "fossil") ALWAYS contain <u>at least one type</u> of organism.
___________________________________________
As such, neither Juan nor Christina are correct. 
   And as such, Answer choice: [C] is the correct answer.
_____________________
Answer choices A, B, and D are ruled out.
