Answer:

Towards the southern of the sound

Explanation:

As the motion of the source of sound is moving,the percieved sound frequency varies .this is known as Doppler effect.the sound waves emited by the sources tends to bunch up in front of the source and spread out behind the source.

Since the falcon is moving towards the sound,the frequency increases and so does the pitch of the sound

Eukaryotic cells are able to trigger the release of material from secretory vesicles to the extracellular space using a process
frozen [14]

Answer:

hormones

Explanation:

An example of materials commonly released this way is hormones. These are chemical messengers that are sent to the pituitary gland where they are released directly into the bloodstream. The blood then carries the hormones to different organs and tissues of the body in order to exert their specific function which varies depending on the specific type of hormones being secreted.

Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2​
marissa [1.9K]

Answer:

A 0.015M

Explanation:

Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:

Molarity (M) = mole (n) / volume (L)

Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.

We can calculate the number of moles of KCl in the solution by using the formula:

Mole = mass ÷ molar mass

Where atomic mass of; K = 39, Cl = 35.5

Molar Mass of KCl = 39 + 35.5

= 74.5g/mol.

Mole = 0.83g/74.5g/mol.

mole = 0.01114

Approximately, n = 0.011mol

Hence, molarity = 0.011mol/0.75L

Molarity = 0.0146

Molarity = 0.015M
