A sample of an unknown material weighs 300 N in air and only 200 N when submerged in an alcohol solution with a density of 0.70 x 103 kg/m3 . What is the force due to gravitational acceleration? What direction does this force act?
What is the magnitude of the buoyant force? What direction does this force act?
What is the density of the unknown material?

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

You are given two vectors a⃗ =−3.00ι^ 5.00j^ and b⃗ =5.00ι^ 2.00j^. let the counterclockwise angles be positive.
