Matter is radioactive and decays over time
Henri Becquerel discovered that <span>uranium salts spontaneously emit a penetrating radiation that can be registered on a photographic plate.

Answer: degrees divided by 360
Explanation:
Fc=mv^2/r so we get
2000kg*(25m/s)^2/(80m)= 15625N of force
hope this helps! Thank You!!
Answer:
V=15.46m/s
Explanation:
By making an energy balance:
Initial energy:
where K=1100N/m and X=4m
Final energy:
where m=60kg and h=2.5m
Work done by friction force: -Ff*X where Ff = 40N and X=4m
The balance will be:
Solving for V:
using g=9.8m/s^2
Answer:
All of the above ! Hope this helps! ♥
