Which of the following is an example of changing the impulse of a collision? question 2 options: a boxer turning his head while being punched. a truck smashing into two-layered retaining wall. removing mass from a ship before it collides with an iceberg. a sugar-glider slowing down mid-air before hitting the ground.

By definition, Momentum = Mass x Velocity.

Let us examine the given statements, and decide whether the impulse of the momentum is either LOWERED, INCREASED, or UNCHANGED.
 
Case 1: A boxer turns his head while being punched.
By turning his head away from the incoming punch, the boxer lowers the
velocity with which the punch is delivered.
LOWERED

Case 2: A truck smashes into a two-layered retaining wall.
Neither the mass nor the velocity of the truck changes before impact.
UNCHANGED

Case 3: Mass is removed from a ship before it collides with an iceberg.
By removing mass from the ship, the momentum is lowered.
LOWERED

Case 4: A sugar-glider slows down in mid-air before hitting the ground.
By lowering the velocity, momentum is lowered.
LOWERED

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

Hi im  doing the same thing u did to me  a black rooster mates with a white hen.  based on their genotypes, the chance that the offspring will be checkered is 100 percent.  what is the rooster’s genotype?   what is the hen’s genotype? the rooster genotype is  bb  bb  bb  bw  .  the hen’s genotype is  ww  ww  ww  bw  .
