96Cm →94 Pu +2 He
A. There is conservation of both nucleons and atoms.
B. The nucleus of an atom changes.
C. The number of atoms is conserved, but the number of nucleons is
not.
D. It involves more than one element.

The completed equations are as follows: 2713Al+42He⟶3015P+10n 13 27 Al + 2 4 He ⟶ 15 30 P + 0 1 n; 23994Pu+42He⟶24296Cm+10n 94 239 Pu + 2 4 He ⟶ 96 242 Cm + 0 1 n; 147N+42He⟶178O+11H 7 14 N

The Nucleus of an atom change

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
