2b(ii) to calculate the seperation how we do it

look,the VOLUME occupied by each atom is in "cm3" and if u'll notice the unit of separation of the atoms is given in "cm". So to remove the cube from the "cm3", just take the cube root of the volume occupied by each atom,and that'll convert the value to '"cm" so thats ur answer....its actually just a game of words

it is a formula u gave to noe dat whenever we calculate the separation we cube root the volume

S05 Q4c
hard ball:all the kinetic energy gets converted to strain energy and when it hits the window it is more likely to break it cuz while hitting the window it doesnt deform

 

[applepie1996]

Man u awsum ))

y i didn't answer da question

 

[Saad (سعد)]

Why are there two threads for the same thing?

Okay...

In the syllabus, we have:

(e) describe the effect of a uniform electric field on the motion of charged particles.

And in the notes, I have things like Equipotential Surface, Potential Gradient, and 'Electric field lines must meet the surface at right angles'.

... What in the realm of Physics is this?

i dun't noe bout ur notes but i never heard words lyk equipotential..............

W05 Q4
for the acceleration draw a tangent from the origin take two points and find the acceleration
for the distance
distance moved=area under the graph
so there are approximately 1550 squares
every 100 squares (1 box) is = 0.1 x 2 = 0.2 cm
s0 1550/100=15.5
15.5 x 0.2 = 3.1cm = 0.031m

if the separation of fringes increases then is it always that brightness of fringes will decrease??

i'm sorry but i'll try 2 do it and tell u as soon as possible

i will be waiting

i want to ask:​

Question 1 (b). Help will be highly appreciated

 

[Muffy94]

hello everyone!!
can anybody tell me what's the value of 'g' we use in physics???
is it 10 or 9.81????

 

[raamish]

9.81 unless its written to take it as 10
