Answer:
After time 2t, the wheel will turn through an angle of 100 rad.
Explanation:
Given;
initial velocity of the wheel,
time of motion, t = t
angular distance, θ = 25 rad
The constant angular acceleration is calculated as;
Therefore, after time 2t, the wheel will turn through an angle of 100 rad.

Answer:
The atomic nucleus is the small, dense region consisting of protons and [[]]s at the center of an atom
Explanation:
Answer:
1 eV = 1.60 * 10^-19 J work done in accelerating electron thru 1 V
KE (total energy) = 1350 ^ 1 eV (note proton goes from + to -)
KE = 1.60 * 10^-19 * 1350 = 2.16 * 10^-16 Joules
1/2 m v^2 = KE = 2.16 * 10^-16 J
v^2 = 4.32 * 10E-16 / 1.67 * 10-27 = 2.59 * 10^11
v = 5.09 * 10^5 m/s
