Answer:
The box of rocks will have depression which can be seen without touching the box.
Explanation:
The density of rocks is very large as compared with napkins. So, the weight of the rocks will be much more greater than that of napkins.
As both boxes have same volume the heavier box will show depression on the lower surface as compared to the lighter box. So, the box of rocks will have depression which can be seen without touching the box.
Answer:
orbit the sun have very elliptical orbits
are made of frozen gas and ice
Explanation:
Comets are the made up of dry ice, frozen water, gases and dust particles. it is called dirty snow balls as their nucleus carry frozen water and pieces of rock.
Comets move around the sun in an elliptical orbits and follow Kepler's Laws saying that they move faster when closer to the Sun.
Comets have tails even when they are far from the sun and the tails that point away from the sun.
Hence, the correct options are "orbit the sun have very elliptical orbits and are made of frozen gas and ice".
The temperature of a fluid rises when energy is given to it. This phenomenon can be described by the equation:
Q = MCp ΔT
where,
Q is the quantity of added energy.
M is the fluid's mass.
The fluid's heat capacity is denoted by Cp.
T stands for temperature change.
<h3>What happens to a fluid's kinetic energy as the temperature rises?</h3>
The mean kinetic energy of the particles in a liquid rises with temperature. The molecules' higher average kinetic energies allow them to more easily overcome the attraction forces that keep them bound together.
<h3>Which temperature rise makes liquids more fluid?</h3>
The most significant determining factor for fluidity is pouring temperature. Therefore, the fluidity increases as the pouring temperature increases.
<h3>How does a liquid react when the temperature rises?</h3>
Particles in a solid, liquid, or gas move more quickly as its temperature rises. The particles slow down as the temperature drops. When a liquid is sufficiently cooled, it turns into a solid.

In order to create a magnifier in convex lens, you should choose a short focal length that is lesser than 1 meter.
<h3>What is a
convex lens?</h3>
A convex lens is also referred to as converging lens and it can be defined as a type of lens that typically causes parallel rays of light with respect to its principal axis to come to a focus (converge) and form a real image.
In Science, a magnifier refer to an optical instrument that allow us to look at a very near object because its image is generally formed farther away. Thus, the image of the object appears to be much larger.
In this context, you should choose a short focal length that is lesser than 1 meter when you want to create a magnifier in convex lens because the nearer the object is to the lens, the larger would be the image formed.
