The net force acting on the block is ~
So, the Answer in the boxes will be ~
Radioactive "decay" means particles and stuff shoot OUT of a nucleus.
After that happens, there's less stuff in the nucleus than there was before.
So the new mass number is always less than the original mass number.

Answer:
4.465 m
Explanation:
Taken the beam to be uniform, then the center of gravity will act at the mid-point of the beam. The mid point = 11 / 2 = 5.5 m
since the boy can walk to the end of the beam without falling,
then the torque ( moment of the force) by beam = torque by students at the end of the beam
let the distance of the boy = x
220 ( 5.5 - x ) = 51 × x
1210 - 220 x = 51 x
1210 = 51 x + 220 x
1210 = 271 x
x = 1210 / 271 = 4.465 m
Answer:
T1 cos 15 = T2 cos 26
T1 = T2 cos 26 / cos 15
T1 = 0.930 T2 ------------(1)
T1 sin 15 + T2 sin 26 = m g
substitute eqn(1)
(0.930 T2 ) sin 15 + T2 sin 26 = 230 * 9.8
0.241 T2 + 0.438 T2 = 2254
Tension in right cable T2 = 3319 N
substitute in eqn (1)
T1 = 0.930 * 3319
Tension in left cable T1 = 3087
