Select the correct statement about osmolarity. a) Osmolarity measures the moles of solute per liter of solution. b) The contents
8090 [49]

Answer:

a) Osmolarity measures the moles of solute per liter of solution.

Explanation:

Osmolarity is defined as the number of moles of solute that contribute to the osmotic pressure, per liter of solution, of solution. That is, the measurement of the solute concentration. The prefix "osmo-" indicates the possible variation of the osmotic pressure in the cells, which will occur when the solution is introduced into the body.

A 100g mass is swung around a tube 50 times in 1 minute. A. Calculate the angular velocity of the 100 g mass.
sergey [27]
The angular velocity is defined as "the angle changing over time." 

From the given of the problem:

m = 100g
rate of revolution = 50 rev / min

Therefore, using the formula:

angular velocity = rate of revolution x 2*pi / revolution

Substituting:

angular velocity = (50 revs / min) x ( 2*pi radians / rev ) = 100*pi radians / min

As you can see, mass is not a part of the equation for solving the angular velocity therefore the amount of mass does not affect its value.

Which statement best describes the work and energy in these examples?
solniwko [45]

Answer: <u>Option A: </u>The gas and food are examples of energy.

Explanation:

Work and energy are inter-related. Energy is required to do the work. An equal amount of energy is converted into work. Work and energy have same units. The SI unit is Joule.

The gas and food are sources of energy. They act as fuel. This energy is utilized to perform work. The gas is used to run the car. The food is metabolized inside the body which is a source of energy and utilized to perform every day work.

Hence, The gas and food are examples of energy.
