A car of mass M = 1000 kg traveling at 65.0 km/hour enters a banked turn covered with ice. The road is
banked at an angle 0, and there is no friction between
the road and the car's tires as shown in figure 1. What is the radius r of the turn 0=20.0*?

orange juice has a lower viscosity

hope it : )

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 is a. at the equator

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
