A team of geologist learn from GPS data that too continents can I have an ocean between them are moving toward each other Diego‘s little brother hears this and cannot believe that continents can move and is worried that those two continents are going to run into each other how can you explain to him what's happening
Answer:
Kindly check explanation section.
[tectonic activity].
Explanation:
What the team of geologists were talking about is known as the continental drift. The term continental drift which was introduced in the 1500s by people like Abraham Ortelius was mot accepted because the reasons backing it were not sufficient enough. The work on Continental drift was also worked on by people like Charles Lyell, Alfred Russel and Wegener. The term continental shift is used by geologists and other scientists to explain the movement of continents over time. The movement of continents is actually the movement on tectonic plates.
Although the movement of continents has not been accepted generally in those times, there has been modern evidence to back it up such as the record on fossils found in in several continents which are similar.
Diego‘s little brother should be told that different continents move at different rate and the movement is on the tectonic plates.
Define a force.......
Answer:
Gravitational Force.
Gravitation is the agent that gives weight to objects with mass and causes them to fall on the ground when dropped.
Answer:
A force is the strength or energy as an attribute of physical action or movement.
Explanation:
In smaller words, a force is a form of energy caused from a push or a pull on an object. A force happens when two objects interact with each other. For example, when you throw a ball you are using force.
Hopefully this helps im sorry if i got it wrong im kinda dumb... XD
a piece of metal has a mass of 1.3 g/cm and a has a volume of 24.9 cm3 what is its mass
Answer:
34.611g
Explanation:
mass of metal = ?
density of metal = 1.39/cm³
volume = 24.9 cm³
density = mass/volume
mass = density × volume
= 1.39g/cm³ × 24.9 cm³
= 34.611g

Q7. Pb + O2 PbO2
Is this combustion, single replacement, double replacement, synthesis, or decomposition
Answer:
This is a synthesis reaction.
Explanation:
Two elements are bonded together to form (synthesize) a new compound.
True or False: The isotope with the greatest
abundance contributes to the atomic mass
reported on the periodic table more than
the isotope of lower abundance.
Answer:
True
Explanation:
Greater abundance means there is more of those isotopes, so they contribute to the average number more. The average number is the atomic mass.
The gravitational attraction between two objects is determined by the mass of the two objects and the:
A. Distance between the objects
B. Weight of the objects
C. Diameter of the objects
D. Density of the objects
Answer:
A. Distance between the objects
Explanation:
The gravitational attraction between two objects is determined by the mass of the two objects and the distance between the two objects.
According to Newton's law of universal gravitation:
"the gravitational force of attraction between two bodies is directly proportional to the product of the their masses and inversely proportional to the square of the distance between them".
F = [tex]\frac{Gm_{1}m_{2} }{r^{2} }[/tex]
F is the gravitational attraction
G is the universal gravitation constant
m is the mass
r is the distance
We can see that the gravitational attraction depends on the mass of the bodies and the distance between them.

Calculate the number of moles of neon gas in 8.15 x 10^24 atoms of neon gas.
1.35 moles Ne
0.135 moles Ne
135 moles Ne
13.5 moles Ne
Answer:
13.5 moles of Ne
Explanation:
1 mole of any gas contains 6.02 x 10²³ atoms of gas
6.02 x 10²³ atoms of neon is equal to 1 mole of neon .
8.15 x 10²⁴ atoms of neon is equal to 1 x 8.15 x 10²⁴ / 6.02 x 10²³ moles
= 8.15 x 10²⁴ / 6.02 x 10²³ mole o neon
= 13.5 moles of Ne .

Can an Atom be broken down into a smaller substance? Yes or No Explain.
Answer:
Yes
Explanation:
A atom is made out of 3 elements, protons which are positive charges, electrons which are negative charges that swirl around the atom, and a neutron with a neutral charge. The nucleus of the atom is basically the center of the atom.
How could measuring the melting point of a solid help decide whether it was a mixture or a compound?
Answer: It can't.
Explanation:
In most cases, the melting point alone will not enable you to identify a compound. Millions of solid organic compounds, and their melting points, are known. Perhaps 10,000 of these will have the same melting point as your unknown compound.
Hope this helps!

What is the mass of 1.2 mol IrI3?
Answer:
690 g IrI₃
Explanation:
To convert from moles to grams, you have to use the molar mass of the compound. The molar mass of IrI₃ is 572.92 g/mol. You use this as the unit converter in this equation:
[tex]1.2molIrI3 * \frac{572.92g}{1mol} = 687.504 g IrI3[/tex]
Round to the lowest number of significant figures which is 2 to get 690 g IrI₃.
