Answer:
vf = 50 m/s
Explanation:
The equation for this kinematic problem is:
vf = vi + at
We are given:
a = 10m/s^2
vi = 0m/s
t = 5 sec
vf = ?
Solve for final velocity:
vf = 0 + 10(5)
vf = 50 m/s
Answer: it’s D
Explanation: ap3x approved
I had the SAME problem, put down Radiation and it’s thermal/light.
V = 20 m/s
Ecin = 1.8 x 10^5 J
Ecin = m*v^2/ 2
1.8*10^5 = m*400/2
200m = 1.8*10^5
I know you can do it :)
Answer:
Structures are determined by two principal factors: the relative sizes of the ions and the ratio of the numbers of positive and negative ions in the compound.
