Aship is able to float on water because it has a higher density than the water.

False.

Explanation:

The ship is capable of floating because its average density (considering the steel part and the air filled part) is less than the water density. Moreover, it is in equilibrium, partially immersed and subject to the action of two forces of the same and opposite modulus, the weight P and the thrust E, exerted by water.

But the stability of the ship does not depend on it alone. It also depends on the point of application of these forces. The weight force is applied to the center of gravity (CG), which is fixed, and the thrust is applied to the center of thrust (EC), which is variable.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
