Asolid, homogeneous sphere with a mass of m0, a radius of r0 and a density of rho0 is placed in a container of water. initially the sphere floats and the water level is marked on the side of the container. what happens to the water level, when the original sphere is replaced with a new sphere which has different physical parameters? notation: r means the water level rises in the container, f means falls, s means stays the same.
the new sphere has a density of rho = rho0 and a mass of m < m0.the new sphere has a mass of m = m0 and a radius of r > r0.the new sphere has a density of rho = rho0 and a radius of r > r0.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
