How are moving pulleys different from fixed-position pulleys? (Points : 3) Moving pulleys have more force than fixed-position pulleys. Moving pulleys are easier to use than fixed-position pulleys. Moving pulleys are attached to the object and move with the object. Fixed-position pulleys are connected to a fixed point and do not move. Moving pulleys are attached to the object and are stationary. Fixed-position pulleys are connected to a fixed point and move freely.

A material that can be represented by a chemical formula is a chemical compound.
What are chemical compounds?
Chemical compounds are substances made up of two or more different elements that are chemically bonded together in a specific arrangement. The elements in a compound can be either metal or nonmetal elements, or a combination of both.
Here,
A chemical compound is a substance made up of two or more different elements that are chemically bonded together. The chemical formula of a compound provides information about the types and numbers of atoms in a molecule of the compound.
For example, water is a chemical compound represented by the formula H2O, which tells us that each molecule of water contains two hydrogen atoms (H) and one oxygen atom (O) bonded together.
Chemical formulas are important tools for chemists to communicate information about the composition and structure of compounds. They allow scientists to predict how compounds will react and to design new compounds with desired properties.

In series, the resultant resistance is their sum: x + y = 108
Notice that y = 108 - x. I think we'll use that very soon.
In parallel, the resultant resistance is (their product) / (their sum) = xy/108 = 24
Multiply each side by 108:
xy = 2,592
Substitute for 'y' :
x(108 - x) = 2,592
108x - x² = 2,592
-x² + 108x - 2,592 = 0
x² - 108x + 2,592 = 0
Use the quadratic formula to find:
x = 72 . . . then y = 108 - 72 = 36
or
x = 36 . . . then y = 108 - 36 = 72
The individual resistors are 36Ω and 72Ω .

Water is placed at room temperature at 20 degree C
now after some water evaporate at room temperature
so here we can say speed of water molecules will not change as the temperature is same after evaporation
as we know that total kinetic energy is given by
since temperature is same then energy will not change here
now as water evaporate to vapors then we can say that here all molecules are separated more in vapor phase so force of interaction will be less in this phase
And since potential energy depends on the force so potential energy will decrease in this phase

Answer;
loud noise that damages hair cells
One of the leading causes of permanent damage leading to hearing impairment is loud noise that damages hair cells.
Explanation;
- Loud noise is the among the leading cause of permanent damage of the ear which impairs hearing.
- Loud noise may cause damage to the cells and the membranes in the cochlea of the ear. Listening to loud noise for a very long time overworks the hair cells that may make them to die.
- The damage to the cochlea of the ear causes permanent hearing loss since all or part of the inner ear has been damaged.
of the ear machinery is prolonged exposure to loud noise or loud music,
which damage the tiny hair cells that stimulate nerve endings in the inner ear.
