Rank the magnitude (absolute value) of the momentum of the following systems from least (1) to most (6)

1. a 100 kg new england patriot running at 8 m/s toward a 120 kg denver bronco running toward the patriot at 7 m/s
2. a 0.300 kg baseball being thrown with a speed of 40 m/s.
3. a 100 kg go-cart moving at a speed of 9 m/s overtaking another 120 kg go-cart moving in the same direction at 8 m/s.
4. a.020kg bullet flying at 1000 m/s.
5.a 1000 kg car moving with a velocity of +20 m/s toward a 10,000 kg truck moving toward the car with a velocity of -2 m/s.
6. a 10 kg baby crawling at 0.25 m/s. 3

The order of the different choices from least (1) to most (6) is as follows:

1  = 5

2 = 6

3 = 2

4 = 4

5 = 1

6 = 3

Explanation:

The total momentum for each system can be expressed as follows:

1) m₁*v₁ +m₂*v₂ = 100kg*8m/s -140kg*7m/s = -40 Kg*m/s

Absolute Value : 40 Kg*m/s

Ranked Nbr. 5.

2) mb*vb = 0.3Kg*40m/s = 12 Kg*m/s

Ranked Nbr. 3

3) m₁*v₁ + m₂*v₂ = 100 kg*9m/s + 120Kg*8m/s = 1,860 Kg*m/s

Ranked Nbr. 6

4) mb*vb = 0.020 kg* 1,000 m/s = 20 kg*m/s

Ranked Nbr. 4

5) mc*vc + mt*vt = 1,000 kg*20 m/s -10,000 kg*2m/s = 0

Ranked Nbr. 1

6) mb*vb = 10 Kg*0.25 m/s = 2.5 Kg*m/s

Ranked Nbr. 2

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.

the results is a decrease in air temperature with an increase of altitude.
