In order to find the force (F), you would have to use the formula for it:
F=ma
where m is mass and a is acceleration.
In the problem, the mass is 2.85kg and the acceleration is 4.9m/s^2.
Therefore,
F=2.85kg(4.9m/s^2)
F=13.965kg(m/s^2)
Since N=kg(m/s^2)
F=13.965N
And because the problem requires that we use only 2 significant figures,
F=13N
Therefore, the student must exert 13N of force.
False! Because it turns from weight to mass
It’s a total of 16 cm because it starts at 0 moves then moves to left then the right then the left
The particles released during alpha decay are called alpha particles. Alpha particles have greater mass and charge than other emitted particles.
- Radioactive emissions are the transfer of energy through the flow of particles or waves in a medium
- There are 3 types of radioactive emissions which are alpha, beta and gamma
- In alpha radiation, the nucleus emits an alpha particle which is equivalent to a helium nucleus
- In beta radiation, an electron is emitted to convert a neutron to a proton
- In gamma radiation, the nucleus just loses energy
Since alpha particles have more mass and charge, they are more ionising and lose more energy at a faster rate and can be blocked easily.

Augmentation or deduction of kinetic energy will tell you if any work is done here.
Explanation:
Here,
E<sub>k0</sub>=0.5mv<sub>0</sub><sup>2</sup>=16,537.5 J
E<sub>kf</sub>=0.5mv<sub>f</sub><sup>2</sup>=194,400 J
Now,
E<sub>k0</sub> - E<sub>kf</sub> = 177,862.5 J
Hence, work is done.
