The amount of heat required to convert 10 gm of ice at - 5°C to water at 75°C is [Latent heat of fusion of ice= 80 cal/gm latent heat of vaporization of water = 540 cal/gm, specific heat of water=1 cal/gm/°C and specific heat ofice=0.5 cal/gm/°C]​

What must be the same for any two resistors that are connected in series ? a. the potntial diffrence across each b. the rate at which charge moves through each c. the rate at which energy is used by each d. the resistance to the flow of charge of each

What is the angular momentum of the bar about the axle?

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
