In order for a boat to float, its weight must have a magnitude equal to the

Which of the following is considered to be a vector?               a.  temperature    b.  velocity    c.  time    d.  mass

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.
