Answer:
if it were to be digital then you would be able to carry it around where ever and look at it to remind you of the memories, however it probably wouldnt last as long as the physical one. eg if you phone breaks there is a chance to restore the photo but you would had to have backed it up beforehand.
Answer:
r = 0.0414mm
F = 757,692.3Hertz
Explanation:
If the body enters space with uniform magnetic field B, the force experienced by the object is expressed as
F = qvBsintheta... 1
Also, if the body undergoes a circular motion, the force experienced by the body in a circular path is given as
Fc = mv²/r... 2
Equating both forces
F = Fc
qvBsin theta = mv²/r
Since the body enters perpendicular to the field, theta = 90°
The equality becomes;
qvB sin90° = mv²/r
qvB = mv²/r
qB = mv/r
r = mv/qB
Given mass of the electron m = 9.11×10^-31kg
Velocity of the object v = 197m/s
Charge on the electron q = 1.6×10^-19C
Magnetic field B = 2.71×10^-5T
Substituting this value into the equation to get the radius r we have;
r = 9.11×10^-31 × 197/1.6×10^-19 × 2.71×10^-5
r = 1794.67×19^-31/4.336×10^-24
r = 413.89×10^-7
r = 0.0000414m
r = 0.0414mm
b) Frequency of the motion F = w/2π where w is the angular velocity
Since w = v/r
F = (v/r)/2π
F = v/2πr
F = 197/2π(0.0000414)
F = 757,692.3Hertz

Examples of student-led organizations are:
- Academic and educational organizations
- Community service organization
- Media and publications organizations
- Political or multicultural organizations
- Recreation and sports organizations
- Student government organizations
- Religious and Spiritual organizations
The benefits of getting involved in any of these are many. They include but are not limited to:
- It helps one to learn more about oneself
- It is a great place to develop leadership skills
- It offers the opportunity for people to build life-long networks
- Skills learned in class can be practiced and honed in these organizations
- Soft skills such as team-intellignce, and social intelligence can be learned in these organizations
- Valuable experiences that count in real-life jobs can be learned here
- It is also an opportunity to give back to the community and to have fun
