Answer:
A channel in an ancient Martian "riverbed" wasn't carved by liquid water but was built by molten lava, according to a new study of surface features on Mars. ... On Earth, lava tubes form during sustained volcanic eruptions, when lava flowing through previously solidified masses leaves behind empty channels in the rock
Explanation:
The lava, itself (when liquid) is very much above the boiling point of water, so it is not wet with liquid water, so it's a no in that sense,' he writes. ... Lava does contain a lot of water, especially prior to eruption (when it's called magma), but also as it flows across the ground,' he explained.
We have this function for kinetic energy :
We find this from the above function :
Due to this equation, the mass of an object and its velocity are inversely proportional to each other.
Therefore, as the mass increases, the speed decreases and the thrown object travels a shorter distance.
And we're done...
Thanks for watching good luck ♥️♥️♥️♥️♥️.

Density is equal to the mass of the substance per volume it occupies. In ths case, the density of gold from literature is 19,300 kg/m3 or 19.3 g/cm3. Given the volume of <span>4.20cm^3 , the mass is obtained by multiplying density and volume to get 81.06 grams of gold</span>
Answer:
A. Calorimeter
Explanation:
A calorimeter is an apparatus that can be used to measure the quantity oh heat in a chemical reaction or the amount of heat that accompanies a physical change and also determine the specific heat capacity of a substance.
It is used extensively in physics, chemistry and the study of thermodynamics. In its simplest form, a calorimeter contains a thermometer which is attached to a container filled with water and suspended above a combustion chamber.
