You have a bag of cotton and an iron bar, each indicating a mass of 100 kg when measured of a weighing machine. In reality, one is heavier than the other. Can you say which one is heavier and why?

To determine which object is heavier between a bag of cotton and an iron bar, both of which indicate a mass of 100 kg on a weighing machine, we need to analyze the concept of apparent weight and buoyancy. ### Step-by-Step Solution: 1. **Understanding Apparent Weight**: - The weighing machine measures the apparent weight of an object, which is the force with which the object pushes down on the scale. This force is affected by buoyancy when the object is in air. 2. **Forces Acting on the Cotton Bag**: ...

There are two cylinder shaped wooden billets, each having a mass of mass 45kg , in a vertical wall sewage, which contains water in it. the two billets have the same size and the same material, they touch each other and the walls of the sewage. One of them is totally under the water, whilst only half of the other one is immersed into the water. Friction is negligible everywhere. (density of water is 1000kg//m^(3) and g=10m//s^(2) ). Choose the correct option(s)

Two astronauts have deserted their spaceship in a region of space far from the gravitational attraction of any other body. Each has a mass of 100 kg and they are 100 m apart. They are initially at rest relative to one another. How long will it be before the gravitational attraction brings them 1 cm closer together?

Two neutron stars are separated by a distance of 10^(10) m . They each have a mass of 10^(30) kg and a radius of 10^(5) m . They are initially at rest with respect to each other. As measured from the rest frame, how fast are they moving when (a) their separation has decreaed to one - half its initial value, (b) they are about to collide .

A projectile of mass 50 kg is shot vertically upwards with an initial velocity of 100 m//s . After 5 s , it explodes into two fragments, one of which having a mass of 20 kg travels vertically up with a velocity of 150 m//s : a. What is the velocity of the other fragment that instant? b.Calculate the sum of rnornenta of fragment 3s after the explosion. What would have been the momentum of the projectile at this instant if there had been no explosion?

A light rope fixed at one end of a wooden clamp on the ground passes over a tree branch and hangs on the other side. It makes an angle of 30^0 with the ground. A man weighing (60 kg) wants to climb up the rope. The wooden clamp can come out of the ground if an upward force greater than 360 N is applied it. Find the maximum acceleration in the upward direction with which the man can climb safely. Neglect friction at the tree branch. Take g=10 m/s^2

The main application of osmotic pressure measurement is in the determination of the molar mass of a substance which is either slightly soluble or has a very high molar mass such as proteins, polymers of various types and colloids.This is due to the fact that even a very small concentraion of the solution produces fairly large magnitude of osomotic pressure.In the laboratory the concentrations usually employed are of the order of 10^(-3) to 10^(-4) M.At concentration of 10^(-3) mol dm^(-3) , the magnitude of osmotic pressure of 300 K is : P=10^(-3)xx0.082xx300=0.0246 atm or 0.0246xx1.01325xx10^5=2492.595 Pa At this concentration, the values of other colligative properties such as boiling point elevation and depression in freezing point are too small to be determined experimentally. Further polymers have following two types of molar masses : (A) Number average molar mass (barM_n) , which is given by (undersetisumN_iM_i)/(undersetisumN_i) where N_i is the number of molecules having molar mass M_i . (B) Molar average molar mass (barM_m) , which is given by (undersetisumN_iM_i^2)/(undersetisumN_iM_i) Obviously the former is independent of the individual characteristics of the molecules and gives equal weightage to large and small molecules in the polymer sample.On the other hand later gives more weightage to the heavier molecules.Infact with the help of a colligative property only one type of molar mass of the polymer can be determined. One gram each of polymer A (molar mass=2000) and B(molar mass=6000) is dissolved in water to form one litre solution at 27^@C .The osmotic pressure of this solution will be :

105 goats, 140 donkeys and 175 cows have to be taken across a river. There is only one boat which will have to make many trips in order to do so. The lazy boatman has his own conditions for transporting them. He insists that he will take the same number of animals in every trip and they have to be of the same kind. He will naturally like to take the largest possible number each time. Can you tell how many animals went in each trip?
