mv= 5 x 2257 = 1.30j. so over all it all equals 167.1J

im poor i don't got the text... heh. and i can't barrow the text from a friend right now

ok so if i got this right Q = mC\Delta T so Q=(5)(4.187)(80)=1674,8kj. So what does v stand for in mLv?? m is mass and L is specific heat constant of water right?

ok by online sources the formula to change water 100c to steam 100c is mLv, wat exactly is specific heat capacity? what i got so far is Q=5C80, would it help if i say I am in a 100 level physics class?

All i remmeber is it have a bunch of Q's and the heat was defined by KJ

1. How much heat is required to heat 5 kg. of water from 20C to steam at 100C? I have no idea how to do this, i looked at some stuff online and i don't understand it, could someone explain how i can work throw this problem maybe even work throw it and explain the steps for me. I am more of...

whats the unit measure for impulse? Btw it all makes sense now. Thanks

ok so i have the change in velocity, and time, but the problem says nothing about the change of mass. and don't have the force so I am assuming there's a separate formula involving how much the bullet penetrated that will give me the force or change of mass but I am thinking force. Anyone know...

sorry sounds dumb but what does F,t, delta, and mv stand for?

Homework Statement A bullet of mass 0.010 kg and speed of 100 m/s is brought to rest in a wooden block after penetrating a distance of 0.10 m. This process takes 0.02 seconds. Theblock remains stationary during this process. a. what is the magnitude of the impulse delivered to the bullet...
