The block coefficient (CB) is calculated as the ratio of the underwater volume of a ship's hull to the volume of a rectangular block that has the same overall length, breadth, and draft as the ship. The formula for block coefficient is: [ CB = \frac{V_{ship}}{L \times B \times T} ] Where: CB = Block coefficient Vship = Underwater volume of the ship's hull L = Length of the ship B = Breadth of the ship T = Draft of the ship

How does a coefficient in front of a formula affect the number of each type of atom in the formula?
A coefficient in front of a formula represents the number of molecules or formula units. It applies to all the atoms within that molecule or formula unit. For example, in the formula 2H₂O, the coefficient '2' means there are two water molecules, resulting in a total of 4 hydrogen atoms and 2 oxygen atoms.
When the block of mass is increased is there an increase in the value of coefficient of kinetic friction?
No, increasing the mass of the block does not directly affect the coefficient of kinetic friction. The coefficient of kinetic friction depends on the nature of the surfaces in contact and does not change with mass.
What force is needed to slide a wooden block having a mass of 300 slugs moving across a floor if the friction is 0.80?
The force needed to slide the wooden block can be calculated using the formula: force = friction coefficient * mass * gravity. Given that the mass is 300 slugs and the friction coefficient is 0.80, the force required will be 2400 lbs.
In the formula 2HgO the coefficient is?
The coefficient in front of the compound HgO in the formula 2HgO is 2. This means there are 2 moles of HgO for every 2 moles of the whole compound.
Experiment to find coefficient of dynamic friction?
To find the coefficient of dynamic friction, conduct an experiment by placing a block on a flat surface connected to a force sensor. Apply a horizontal force gradually to the block until it starts to slide, and note the force required for motion to begin. Use the formula: coefficient of dynamic friction = (force to start motion) / (weight of the block) to calculate the coefficient. Repeat the experiment multiple times to get an average value.
Horizontal force required to pull 75 kg block?
To pull a 75 kg block horizontally, you need to overcome the force of static friction between the block and the surface it's on. The force required would depend on the coefficient of static friction between the block and the surface. You can calculate it using the formula: Force of friction = coefficient of static friction × normal force.
The number placed in front of a chemical symbol or formula is called?
The number placed in front of a chemical symbol or formula is called a coefficient. It represents the number of molecules or formula units in a chemical reaction.
Is the coefficient of friction the same as when the block was standing on its larger (or smaller) end?
No, the coefficient of friction can vary based on the contact surface area and material properties of the block. When the block is standing on its larger (or smaller) end, the contact surface area and the weight distribution changes, which can affect the coefficient of friction.
Does the coefficient of kinetic friction depend on the weight of the block?
No, It does not depends on weight of block because this weight of block is being balanced by normal force. So by increasing weight of block, there is no effect on coefficient of friction.

A 5.0 kg wooden block is placed on an adjustable wooden inclined plane. What is the angle of incline above which the block will start to slide down the plane .57?
mgsin (theta) - (static) mu * mgcos(theta) = 0 rearrange the equation and cancal mg therefore, tan ( theta) = mu (static) theta = arctan (static mu) If the static coefficient is 0.57, then theta = arctan (0.57) theta = 29.7 degree Note: from the equation, the mass of the block is independent to the angle. Whether you have a bigger block or smaller block, it will start sliding @ 29.7 degree.
When the block of mass is increased is there an increase in the value of coefficient of kinetic friction?
No, increasing the mass of the block does not directly affect the coefficient of kinetic friction. The coefficient of kinetic friction depends on the nature of the surfaces in contact and does not change with mass.
