Question 1 If 150 kcal of heat raises the temperature of 2.0 kg of a material by 400°F. what is the specific heat capacity of the material? 0.75 kcal/kg. C 1.35 kcal/kg - c 0.19 kcal/kg . °C 0.34 kcal/kg . °C Moving to another question will save this response.

Answer 1

We know, g=mat Here g= 15okcal , m=2kg AT 400°F = 204.14°C T°C) = (TOF) - 32 ») iSokcal = 2leg.c.204.44 °c => ca le hace mu kcallegoc 3) IC z 0.3676 kcal/kg-oc (0.34 ale to options) The torque on a coil in a magnetic field is given by I- NIAB sine, Im= NIAB if we double the quantities then t'= UN ).(21). (2A).(2B) = 16N IAB = 167 The max torque will increase by a factor of 16.
