Ulysses was working with glassware in the laboratory and accidentally dropped a beaker. he first notified his teacher, put on gloves, swept up the glass quickly, and disposed of the glass in the trash can. which best describes the error ulysses made? he should have cleaned the glass before telling the teacher. he should have used tongs to handle the pieces of glass. he should have put the glass in a broken glass bin. he did not need to wear his gloves.

He should have put the glass in a broken glass bin

Explanation:

Putting broken glasses in the trash can or the dust bin can be hazardous to the workers working at local recycling center as the pieces might hurt them. Instead, he should have thrown the broken beaker in a separate glass bin or should have wrapped properly in paper so that it won't hurt anyone.

Also, glasses have a high melting point and therefore it is not recyclable. Hence, it should be trashed separately.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
