Answer:
"The bowling ball on Earth will have a greater potential energy relative to the surface because the Earth has a much greater mass, and therefore a much stronger gravitational acceleration."
Explanation:
Potential energy acts as a result of the object placed over the Earth's surface, The object has the ability to fall because of the gravitational force. Gravitational potential energy is based on the weight of the object and also the height above the ground surface. But the elastic potential energy acts due to the shape of the object. Potential energy is related with the restoring of the forces which is the spring or the force of the gravity.
Answer:
A) The north pole of a bar magnet will attract the south pole of another bar magnet.
B) Earth's geographic north pole is actually a magnetic south pole.
E) The south poles of two bar magnets will repel each other.
Explanation:
<u>According to </u><u>classical physics</u>, a magnetic field always has two associated magnetic poles (north and south), the same happens with magnets. This means that if we break a magnet in half, we will have two magnets, where each new magnet will have a new south pole, and a new north pole.
This is because <u>for classical physics, naturally, magnetic monopoles can not exist. </u>
In this context, Earth is similar to a magnetic bar with a north pole and a south pole. This means, the axis that crosses the Earth from pole to pole is like a big magnet.
Now, by convention, on all magnets the north pole is where the magnetic lines of force leave the magnet and the south pole is where the magnetic lines of force enter the magnet.
Then, for the case of the Earth, the north pole of the magnet is located towards the geographic south pole and the south pole of the magnet is near the geographic north pole.
And it is for this reason, moreover, that the magnetic field lines enter the Earth through its magnetic south pole (which is the geographic north pole).
Answer:
i think the answer is b kk good luck
Explanation:
Answer:
1. K.E = 11.2239 kJ ≈ 11.224 kJ
2.
3.
Solution:
Now, the kinetic energy of an ideal gas per mole is given by:
K.E =
where
m = no. of moles = 3
R = Rydberg's constant = 8.314 J/mol.K
Temperature, T = 300 K
Therefore,
K.E =
K.E = 11223.9 J = 11.2239 kJ ≈ 11.224 kJ
Now,
The heat capacity at constant volume is:
Now,
Required heat transfer to raise the temperature by is:
Both of them are Heterogeneous mixtures. They can both be separated into their compounds, but not down to the element.
