An iron anchor of density 7850.00 kg/m3 appears 183 n lighter in water than in air.
a. what is the volume of the anchor?
b. how much does it weigh in the air?

Explanation:

a) Weight loss in water = Volume of object x density of water x acceleration due to gravity

183 = Volume of anchor x 1000 x 9.81

Volume of anchor = 0.019 m³

b) Weight = Mass x acceleration due to gravity = Volume x Density x acceleration due to gravity

Weight of anchor in air = Volume of anchor x Density of anchor x acceleration due to gravity

Weight of anchor in air = 0.019 x 7850 x 9.81 = 1463.17 N

Weight of anchor in air = 1463.17 N

  scorpions are animals in the order scorpiones, under the class arachnida, which makes them a distant cousin of spiders

happy to

pls mark as brainliest.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
