When cleaning up a local beach, students found many different particles that were in the water that affected the shoreline, like litter and gasoline. which of the following describe how these items would need to separated from the water? why? question 5 options: both gasoline and litter would need to be physically separated from the water, because neither bonds with the water. both gasoline and litter would need to be chemically separated from the water, because both form new bonds with the water. both gasoline and litter would need to be chemically separated from the water, because neither bonds with the water. litter would need to be physically separated with water and gasoline would need to be chemically separated from water, because both form a mixture with the water.

Litter would need to be physically separated with water and gasoline would need to be chemically separated from water, because both form a mixture with the water.

the correct answer is   Both gasoline and litter would need to be physically separated from the water, because neither bonds with the water.

PS- The guy above me is wrong and i took the test

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h

happy to

pls mark as brainliest

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.
