2. how fast would a 0.25 kg football have to be traveling to have the same momentum as a 0.05 kg bullet travelling 500 m/s?

The football is 100 m/s fast

Explanation:

Momentum is the product of the mass of a body and it velocity. Momentum is a vector quantity . Meaning it has both Magnitude and direction.  Momentum is the mass of a body in motion. Mathematically,

Momentum = mass × velocity

p  = m × v

To calculate how fast the football traveled one needs to calculate for the momentum of the bullet.

Momentum of the bullet = mass ×  velocity

Momentum of the bullet = 0.05 × 500

Momentum of the bullet = 25 kg m/s

Since the momentum of the bullet is equal to the momentum of the football

Momentum of the football = mass × velocity

How fast means calculate the speed which is the velocity

Velocity = Momentum of the bullet/mass

Velocity = 25/0.25

Velocity = 100 m/s

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
