    10 ohm resistor connected to battery. Battery cinnected to voltmeter in parallel. When switch is open voltmeter reads 1.45. When closed it reads 1.26. Calculate internal resistance of battery?
    that gets me 1.5 ohms, does anyone know if that was an answer? (for the last question)

    The multiple choice one? Think I put 4lambda
    is it not lambda/4? I thought cause the mass of alpha particle is 4x that of a proton, it would be 1/4 as its inversely proportional😁

    But I assumed the centre of mass was at the centre of the ball so surely the distance of the ball would be 12+5/2cm

    You had to take the centre of the ball as the line of action didn't you? So the radius length was added on

    i put 100w even though i worked out it to be 114w due to one of the pieces of info that i used being to one sig fig. do you think that is still correct?

    Think you had to use lambda = h/mv. With an alpha particle, there are 4 protons/neutrons, so the equation turns into lambda = h/4mv, leading to 4lambda = h/mv.
