How did everyone find the triple science paper

Specific heat question with two equationsu neededto combine anyone?

What did you put for the difference in distance times for the two cars ? I put at least 10 minutes

Like 0.061kg or something

What i dknt think u were meant to put a specific difference u were meant to explain if it was faster or quivker for diesel. And it wpuldnt have been 10 anyway because the charging time for the batteru was 40 minutes

I’m pretty sure the question was asking about whether electric or diesel would be quicker not specific speeds
What did u guys get for the mass question higher plz!!
lol. it was

It said they travelled at the same speed so I jus put how the electric car would have to stop to charge the car for 10 minutes to charge the battery enough to travel the last 100km

Omfg for the mass of the ice cube I screwed up and didn’t realise the question was in the physics equation sheet which was e=ml 😰😰 still think o got 92/100 thou

I got 0.027
I got 0.016kg for the mass of the ice cube one (8.4) but I used simultaneous equations so I feel like there has to be an easier way
wow, what a nerd. I'm here struggling to get 6's while this dude is flexing 92/100.

Yeah I said 10 minutes charging

but you only needed a quarter charge
How do you do the mass one I didnt know what to do so I made an equation the equaled 5848J and got 0.09 but Ik it’s wrong

What did people get for the expectation value of the hamiltonian question?
0.016 mass of ice cube.
120 Ohms resistance for the defibrillator question.

I said it was quicker for the disel car because the electric had to stop
