Ecology experiment-aquarium half with water is placed scale

Reference no: EM13676564

Through an ecology experiment, an aquarium half full with water is placed on a scale. The scale reads 195 N.

1. A rock weighing 8 N is added to the aquarium. If the rock sinks to the bottom of the aquarium, what will the scale read?

2. The rock is removed from the aquarium, and the amount of water is adjusted until the scale again reads 195 N. A fish weighing 2 N is added to the aquarium. What is the scale reading by the fish in the aquarium?
