How will we calculate it ?? show complete working .. as i have no idea at all how to solve cro questions.

Use the formulae F=1/T so u will get 2 which is for 1 wave then add 1 to it for the half wave !!
Answer is 3 dat is A

Thanks alot

Terminal Velocity means 0 m/s^2 acceleration .. so then the answer will be D right? as in start the speed is more..

A bcoz 0.5 hz means half wave runs across pr second and 1.5 waves are shown so three seconds

yep

Yes its D !! Ur right !

 

[syed1995]

What will be the answer and why? I am confused between A and B.

 

[syed1995]

Yes its D !! Ur right !

For once in my life I am correct in physics..!

Its not a ! They asked of thw whole fall so in the beggining the acceleration will be 10 then as it reaches terminal it will be 0
Got it ? So d is the answer !!

Is the average of 35/40 bad for MCQs ?

Can you please re-explain this question in-detail:

5. w09 qp_2 Question 11 (c) (i)

No not that bad in the case if ur paper 2 is very well attempted !!

Wrong image !!!!

this is the image !!

its D
because after the jump acceleration is greatest and is decelerated by air resistance to zero where terminal velocity starts

My p2 sucks ..

Wrong image link .. Sorry !

It is a factual thing dat it is resistance because the other factors do effect theemf induced so option B

 

[convent2012]

15*60=30x
x=30N
W/g = m
30/10 = m
m = 3kg
option B

thanks

 

[convent2012]

fxd=fxd
so, 30 x weight=(30+30) x 15
weight=60 x 15/30
=30 N now change it to mass by W=mg
30/10= 3 kg
