Answer:

Explanation:
= Mass of Bonzo
= Mass of Ender
= Initial Velocity of Bonzo = 2.2 m/s
= Initial Velocity of Ender = -2.6 m/s
From conservation of linear momentum


Answer:
C. Planet D has the greatest mass and will exert a greater gravitational force
Actually says Pantazis, since their frequencies are so wildly different, brain waves don’t interfere with radio waves. Even if that was the case, brain waves are so weak, they are hardly measurable at all. For comparison, says Pantazis, “the magnetic field of the earth is just strong enough to move the needle of a compass. Signals from the brain are a billionth of that strength.”
Answer:
Given
mass (m) =2kg
velocity (v) =3m/s
momentum (p) =?
Form
p=mv
2kgx3m/s
p=6kg.m/s
the momentum of ball's =6kg.m/s
