Answer:

W_apparent = 93.1 kg

Explanation:

The apparent weight of a body is the weight due to the gravitational attraction minus the thrust due to the fluid where it will be found.

W_apparent = W - B

The push is given by the expression of Archimeas

B = ρ_fluide g V

ρ_al = m / V

m = ρ_al V

we substitute

W_apparent = ρ_al V g - ρ_fluide g V

W_apparent = g V (ρ_al - ρ_fluide)

we calculate

W_apparent = 980 50 (2.7 - 0.8)

W_apparent = 93100 g

W_apparent = 93.1 kg

Fossils are rare because certain conditions are needed to preserve an organism in order for it to fossilize, and those condition

sladkih [1.3K]

Answer:

Explanation:

The least of the conditions that can result in fossilization would be when an organism is a prey to several species.

Fossils are remains or traces of organisms that have been geological preserved and a prey is an organism that is often hunted and serves as food to bigger organisms. When an organism is eaten, the probability of it becoming a fossil becomes low. Unless such an organism is usually partially eaten by predators, there would not be any remains, let alone being fossilized.

The correct option is D.

Help needed Can a body be accelerating if it is moving in circle

belka [17]

Answer:

When a body is moving on a circle it is accelerating because centripetal acceleration is always acting on it towards the center.
