ohh from this thread??it is already solved.check the mcq yearly thread
For question 13, the 900N force and the force 'F' are acting in opposite directions so you'll have to equate their equations. Now the force of 900N is acting at a distance of 0.2m from the centre of the disc (consider it the pivot). So the equation for its moment of force will be = 900 x 0.2
kindly explain plssss :'(u can solve this with the help of trigonometric ratios
Thanks alot!fr this 1 find the force so it will be F(frictional force)+200sin30=250
then find the distance moved by the box in the slope.sin30=1.5/h.u will get 3.then apply the formula w=f*s.250*3=750
remember here the quantities are not added, to find density we use the formula density=mass/volumeThen why is the answer not 0.01+0.01+0.01+0.1 for this one???

thank you ^^ really helpfulFor question 13, the 900N force and the force 'F' are acting in opposite directions so you'll have to equate their equations. Now the force of 900N is acting at a distance of 0.2m from the centre of the disc (consider it the pivot). So the equation for its moment of force will be = 900 x 0.2
The forces 'F' form a couple, so you'll have to take the total distance between the which is 1.2m and multiply it with 'F'. Now equating the equations you'll get:
900 x 0.2 = F x 1.2
Solve it and you'll get F = 150N
in this case..they are divided / multiplied...so it's the fractional uncertainty that will be added...and then we calculate the uncertainty from that..Then why is the answer not 0.01+0.01+0.01+0.1 for this one???

see, if u take the forces the other side, then w will be the perpendicular, f will be the base, then u can apply, tan= f/w i.e base over perpendicularmalik234 pl bro help meee not getting it plssssss waiting for complete solutions pls man
.can u help me with mj11 2,29Thanks alot!
Mass, energy... nucleon number, momentumListen guys, what is conserved in a nuclear reaction and what isn't?
PLEASE HELP I"M REALLY CONFUSED
energy, nucleon number, number of protons is conserved.Listen guys, what is conserved in a nuclear reaction and what isn't?
PLEASE HELP I"M REALLY CONFUSED
Everything except the number of neutrons is conserved.Listen guys, what is conserved in a nuclear reaction and what isn't?
PLEASE HELP I"M REALLY CONFUSED
which variant?welcome
.can u help me with mj11 2,29
The answer's 0.37m/s^2oh sorry i mixed it up with some other mcq, didn't read all..
s= ut + 1/2 at ^2 , total distance = 80 m , u will be zero, time is 18 seconds,
80= 1/2 into a into 324 , 80/162 = .49 ms^-2
the size of the arrows shows the magnitude of the force..W have the smallest arrow..then H is a bit larger than W and t is the greatest so C
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
