Option 4 . Energy is transferred to the tree in this wave.

Explanation:

The figure shows that the rope is tied to tree at one end and at the other end a boy is holding it.

Here the boy swings the rope to give it a sudden movement and due to this movement the transverse waves of sinusoidal form are obtained and gets traveled till the tree.

Here the energy used by the boy to give a quick movement to the rope gets transferred till the other end of the rope that means the energy is getting transferred to the tree.

Along with the energy the particles of the way also gets transferred to the tree unless there is an obstacle.

Therefore in this wave energy is transferred to the tree.

What is the mass of 4.70 mol H2O? Answer in units of g.

Blizzard [7]

Answer:

4.70 moles of water have mass of 84.6g

Explanation:

Given data:

Number of moles of water = 4.70 mol

Mass in gram = ?

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of water is 18 g/mol

Mass = 4.70 mol × 18 g/mol

Mass = 84.6 g

Thus, 4.70 moles of water have mass of 84.6g.

The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is blank liters

Aneli [31]

Answer: 18.97 L

Explanation:

This can be solved by the Ideal Gas equation:

$P.V=n.R.T$

Where:

$P=2 atm$ is the pressure of the gas

$V$ is the volume of the gas

$n=1.5 mole$ the number of moles of gas

$R=0.0821\frac{L.atm}{mol.K}$ is the gas constant

$T=35\°C+273.15=308.15 K$ is the absolute temperature of the gas in Kelvin

Finding $V$ :

$V=\frac{nRT}{P}$

$V=\frac{(1.5 mole)(0.0821\frac{L.atm}{mol.K})(308.15 K)}{2 atm}$

$V=18.97 L$

Therefore:

The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is <u>18.97</u> liters
