I would say height from which the seed is dropped and air resistance.

And I would say mass/weight and surface area

Thank you for pointing out that weight is also a factor. It is a factor because the seed is not falling on moon.And I would say mass/weight and surface area

Salaam... i hv problem in chemistry can some1 suggest me a gud tutor in karachi. Some1 who iz best in chemistry.
Potassium sulfate is K2SO4
If you have any Chemistry question, plz ask me.
If you want to study over Skype, I can suggest u a good teacher from Bangladesh. Thank you.

Guyzz need urgent help!!
The Figure shows two charged particles fixed in place on an axis. (a) Where on the axis (other than at an infinite distance) is there a point at which their net electric field is zero: between the charges, to their left or to their right? (b) Is there a point of zero net electric field anywhere off the axis (other than at an infinite distance)
______+q________-3q____

The answer is D.
It is because the work done he puts to go forward is actually equal to the work he does against the resisting forces. As he is moving at a constant speed the work done is actually equal. So the heat lost is the work he is doing to move forward.

Take the weights of measuring cylinder and the initial block of wood as zero because these two balance each other that will make the calculation simple and actually will have a solution.
Now,
0.39 x (40/100) = W x (30/100)
solve for W and you will have the weight asked.
For the next part W=mg
You got the W in the part before g is 10 N/Kg solve and you will get the mass.
I hope you get it

The mass doesn't matter when the scale is balanced. the torque is zero the anticlockwise moment is equal to the clockwise moment so mass isn't of concern anymore when the scale is balanced.

Structure isnt required doesnt mean you dont have to study about the process of ultrafiltration and rest.
And yes on the safe side the structure should be studied.

This MCQ.
What does a negative gradient of a velocity-time graph indicate,
A. Velocity is increasing.
B. Velocity is decreasing
C. Velocity is constant
D. It does not show velocity at all.
I can't find the answer to it anywhere and my answer is D since the gradient(positive or negative) shows acceleration.

The answer is B because the gradient is decreasing meaning that the velocity on the y axis is decreasing if the acceleration is negative it is decreasing right? So obviously velocity is decreasing too
It is aa velocity-time graph so it can't be D
If velocity was to be constant then the slope would be 0(no acceleration )
