Hi, thanks for the help.. But one qn though. What will the value of (\delta \theta) be? Is it 5? But i though for this to apply, ur change has got to be small? i calculated the value of (\delta \theta) ~sin(\theta) and it is very big? Even bigger than the real value?
How do i find the value of cos(theta) if theta was given as 75(+/-)5?
Ans:____(+/-)_____.
How do i even start with this? How do i find the uncertainty of cos (theta)? Do i use the uncertainty of theta or the fractional uncertainty? Or do i just find cos 80, cos 75 and cos 70 and then find...
ok, the qn goes like this..
Find the first term and common ration of a geometric progression if the sum to n is given by
6 - 2/(3^(n-1))
I tried solving by making both terms of the eqn having the same denominator by multiplying (3^(n-1)) to the first term 6 and then by taking out the 2...
Erm. Okay, to simplify things, its a beaker of half mercury and water. Water above and mercury below. The block is submerged halfway between the liquids. The upper half of the block is in the water and the lower half of the block is in the mercury.
Tried uploading the pic but failed. Will...
Alright.. I have a problem.
I have 2 liquids, mercury and water together in the beaker.
Assuming both liquids are non mixable, the water, with a lower density, will be at the top while mercury will be at the bottom.
Now, I push a block into the water and it floats at halfway between...
Yes. there is air resistance but the fact that the cyclist is moving at constant speed tells us more than just that he is not accelerating. It also tells us that the cyclist have no resultant force down the slope right?
Yes. The max Fx allowed will be the frictional force acting on the 5kg block. You now know that the tension of the string connected to the wall and connection pt does have a vertical pulling force and rightward pulling force. If the max allowable rightward pulling force is given by friction, are...
Note this:"climbs the hill at the same constant speed" What does this imply about the cyclist when he was coming down the hill? What can you find from this?
When he is going up the hill, again wat are the forces that apply on him? Compare the 2 situations, one when the cyclist is coming down...
So.. As you said, since distance is the same, well, you can simply draw out a velocity time graph of both graphs on both diagrams and try working them out right? Its always wiser spending some time drawing the graphs.. Basically, after drawing the graph and working out the equations, you should...
