Tom notes that the the bulb has an effective resistance of 5.0 Ω, that the voltmeter reads 2.0 V and that the ammeter reads 3.5 A.
a) State Kirchoff’s First Circuit Law. What implications does it have for the charge entering and
leaving a circuit junction?
b) State Kirchoff’s Second Circuit Law.
c) Calculate R1.
d) Calculate R2.
e) Calculate the power dissipated by the bulb.

i need the answer to this too but idk it ; -;

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
