Answer: b) Less dense
Explanation:
Differences in density is one reason objects float or sink.
An object more dense than the fluid in which it is immersed will sink, while objects less dense than the fluid in which it is immersed will float to the surface.
But objects floats at constant level if the density is equal to the density of the fluid in which it is immersed; it neither rises nor sinks in the fluid in this case.

Question options:
1. It cannot be determined without knowing which man is stronger.
2. The forces are unbalanced, and net force on the cart moves it to the left.
3. It cannot be determined because one man is taller than the other.
4. The forces are unbalanced, and net force on the cart moves it to the right.
Answer:
<em>2.The forces are unbalanced, and net force on the cart moves it to the left.</em>
Explanation:
In the image, two opposite forces acting on a rolling cart. The person on the right side exerting more force (50N) toward the left than the person on the left side (10N). The more the force applying on the object, it will drag on the followed direction.
It is because the person on the right side exerting force (50N) toward the left, rolling cart will moves to the left.
Hydrothermal metamorphism involves chemical reactions between oceanic lithosphere and warm fluids near mid-ocean ridges
Hydrothermal metamorphism is most common along mid-ocean ridge spreading centers, where warm seawater percolates through hot, cracked basalt. Metamorphism of basalt occurs as a result of chemical interactions between hot saltwater and basalt. On continents, crustal rocks can be metamorphosed by invading, hot fluids associated with igneous intrusions, resulting in hydrothermal metamorphism.
The interaction of a rock with a high-temperature fluid of changing composition results in hydrothermal metamorphism. The compositional mismatch between an existing rock and the entering fluid causes a series of metamorphic and metasomatic processes.
Hydrothermal metamorphism changes Mg-Fe-rich hydrous minerals like talc, chlorite, serpentine, actinolite, tremolite, zeolites, and clay minerals. Hydrothermal metamorphism is frequently responsible for the formation of rich ore deposits.

<span>The kind of intermolecular forces that occur between the toluene and hexane are dispersion forces. Toluene is non polar compound that would dissolve in hexane. These dispersion forces are weak and also called as induced dipole-induced dipole attraction. This form a partially charged that too temporary and this dipole - ions have a short-lived communication.</span>
