Answer:
0.51 m
Explanation:
Using the principle of conservation of energy, change in potential energy equals to the change in kinetic energy of the spring.
Kinetic energy, KE=½kx²
Where k is spring constant and x is the compression of spring
Potential energy, PE=mgh
Where g is acceleration due to gravity, h is height and m is mass
Equating KE=PE
mgh=½kx²
Making x the subject of formula
Substituting 9.81 m/s² for g, 1300 kg for m, 10m for h and 1000000 for k then
The earth tilt about 23 degrees which leads to the formation of seasons on earth.
<h3>At what degree the earth tilt?</h3>
This is tilted at 23 degrees from the vertical. The northern hemisphere is in the winter season.
This is the path as the earth revolves around the sun. It takes 1 year to complete this path.
This is the path as the earth rotates around its.
So we can conclude that the earth tilt about 23 degrees which leads to the formation of seasons on earth.

Answer: 0.8 m
Explanation:
Velocity of throw = 4m/s
Maximum Height attained(h) =?
Downward acceleration experienced = 10m/s^2
Using the relation:
v^2 = u^2 + 2aS
v = final Velocity = 0 (at maximum height)
u = Initial Velocity = 4
a = g downward acceleration = - 10
0 = 4^2 + 2(-10)(S)
0 = 16 - 20S
20S = 16
S = 16 / 20
S = 0.8m
Maximum Height attained = 0.8m

Answer:
<h3>Two-track correctional system is a system of consisting two correctional institutions for criminals.</h3>
Explanation:
- The two-track correctional system is a correctional system that consists of two separate correctional institutions for criminals. One institution for juveniles and one for adult criminals.
- No, two-track correctional system would not work better in our country. There are many cases of serious juvenile crimes in our country. Juveniles who commit serious or atrocious crimes should be dealt strictly in an adult or criminal court without exemption.
- Yes, this would reduce the percentage of offenders re-entering the system because juveniles incarcerated for serious crimes would be locked up in the prison instead of being acquitted after a short detention.
- This would stop them from committing similar offences and would reduce potential crimes from ex-convicted juveniles.
