Vector A⃗ points in the negative y direction and has a magnitude of 5 km. Vector B⃗ has a magnitude of 15 km and points in the positive x direction. Use components to find the magnitude of A⃗ +B⃗ . Use components to find the magnitude of A⃗ −B⃗ . Use components to find the magnitude of B⃗ −A⃗ .

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

b.transmitters send radio waves, and receivers capture radio waves.

grav forces affect all objects magnetic forces affect magnetic objects and electric currents
