Estimate the maximum height of the mountains on a hypothetical planet similar to earth but with twice the surface gravity of our planet.

Four objects are being tested to see how they are affected by fluid friction. object w has a surface area of 4.5 cm2, object x has a surface area of 2.5 cm2, object y has a surface area of 6.2 cm2, and object z has a surface area of 3 cm2. which object would experience the most fluid friction?

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied

An object's buoyant force and weight mean the same thing.a. trueb. false
