Can someone me with these. and correct me if i'm wrong.
1. which of the following is emitted in beta decay.
protons
==> neutrons
gamma radiation
electrons
2. transuranic waste comes mostly from.
==> weapons production
surgical materials
mining wastes
used tools
3. clothing that comes into contact with radiation is considered high-level nuclear waste
==> true or false
4. low-level waste is the least radioactive type of nuclear waste
==> true or false
5. uranium mining is not very disruptive of the land, and therefor nuclear power is much more desirable than coal mining.
==> true or false
6. use of nuclear power instead of coal-burning electricity could mean less carbon dioxide in the atmosphere and less global warming.
==> true or false
7. nuclear power has the advantage over coal in that nuclear power does not produce as much carbon dioxide as coal.
==> true or false

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
