An electric rice cooker rated 800 W, 230 V is switched on for 30 minutes. a) How much electrical energy is used by the rice cooker? b) Calculate the cost of energy that is used by the rice cooker if the cost per kWh is 30 sen.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.

b) the inside picture would look at a very high temperature in a very low ph
