- pressure=(101ce)/(area) A block exerts a force of 5 N on the ground. Calculate the pressure the block exerts on the ground , in N/m^2 , when it is a) flat on the ground, so that the area of its base is 0.04m^2 b) standing up on its side, so that the area of its base is 0.025m^2
- In a newly opened estate the planner had a specified number of occupants for the estate and the electricity board gave them a transformer that could serve the specified number of occupants However the number of occupants eventually increased beyond the planned number due to sub division of the plots and the transformer could not serve the population any more. All people started to complain that their electrical appliances, security lights and security alarms are no longer working and this has brought insecurity in the estate. Hint; Power input of the transformer=12000W, voltage output=240V and the output current= 20A Task As a physics student; (a) Explain why the transformer could no longer serve the big population of the estate. (b) Suggest the possible causes of power losses in a transformer and how they can be minimized. (c) Explain how an electric bell (alarm)works in order to alert people.
