Hiiiii friends......
here is your answer.....
✌✌ Resistive force is a force where direction is opposite to the velocity of body or the sum of the other force and may refer to friction
now force lost by the machine
Answer:
a) intensity 
b) E = 0.0406 V/m
Explanation:
given data:
Power = 30 kW
R = 33×10^3 M
1) Intensity is given as
2) electric field is given as
Solving for E
E = 0.0406 V/m
it is easier to connect cpts by going across the in parllel rather than breaking a conn and reforming it
Answer:
Paper will not stop any radiation.
Copper will stop beta radiation.
Lead will damp the gamma radiation
Explanation:
A Geiger counter is an instrument used to measure the radiation level. There are majorly three types of radiation: Alpha, beta and gamma. Alpha radiations have least energy and gamma radiation have the highest energy. Alpha radiation can be stopped even by a sheet of paper. Beta radiation can be stopped using a sheet of aluminum or copper. To stop the gamma radiation you need lead. Also, the energy of the gamma radiation and thickness of the lead shield will decide how much of the gamma radiation is stopped by the lead sheet.
In the given scenario, when only paper is used neither beta nor gamma radiation will be stopped and Geiger counter will show you the high radiation level. When the source is lined with copper and lead, beta radiation will be stopped and gamma radiation will be damped. So Geiger counter will show reduced level of radiation.
False because they all travel at the same rate
