A gas stove used for heating water when camping has a power rating of 3000 W. The outside temperature is 10 °C and the specific heat capacity of water is 4200 J/kg.
a Calculate the time it would take to boil 250 g of water.
Assume that all the energy transferred is used to heat the water.
Use the equation:
change in thermal energy = mass × specific heat capacity × change in temperature

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?

Which best describes the difference between internal and thermal energy?

Aswimming pool whose volume is 10 comma 000 gal contains water that is 0.01% chlorine. starting at tequals0, city water containing 0.003% chlorine is pumped into the pool at a rate of 5 gal/min. the pool water flows out at the same rate. what is the percentage of chlorine in the pool after 1 hour? when will the pool water be 0.006% chlorine?
