Please help will give brainliest 5. The Tower of Doom, at Elitch Gardens in Denver, Colorado, lifts 15 people 50 m into the air. The engineers assume the average person has a mass of 70 kg.

A. How much rider weight does the ride lift into the air? (Neglect the weight of the cars and air resistance.) (4 points) About 1,050 kg

B. How much force must the ride produce to do this? (4 points)

C. How much work does the ride do to lift the riders up to a height of 50 meters? (4 points)

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 answer for apex is the lowest
