to what direction does the rope move?

Answers

Answer:

This question appears incomplete

Explanation:

However, the direction in which the tension acting on the rope is directed is the direction the rope will move. Hence, when a rope is attached to an object, the rope will only "realistically" move in the opposite direction because the rope cannot push an object but can only pull an object, hence can only move in the direction away from the object.

NOTE: Tension can be defined as the pulling force of an object through the use of a string, chain or anything with a potential to stretch fully.

The mass of an oxygen–18 atom is 18.0042 amu. Compute the calculated mass.

Answers

Answer:

The calculated mass of one atom of oxygen-18  is approximately  2.99×10⁻²³ grams

Explanation:

The given mass of an oxygen-18 atom = 18.0042 amu

The definition of the atomic mass unit is the mass equivalent to the mass of one twelfth the atomic mass of one atom of carbon-12. The atomic mass unit is used to express the mass of an isotope of an element

1 amu = 1.66 × 10⁻²⁴ grams

Therefore;

18.0042 amu = 18.0042 ×  1.66 × 10⁻²⁴ grams ≈ 2.99×10⁻²³ grams

The calculated mass of one atom of oxygen-18 ≈ 2.99×10⁻²³ grams

The atomic mass unit can be taken as the mass in grams of one mole of the substance

Therefore, the mass of one mole of the oxygen 18 atom = 18.0042 g

Which ion is found in all acids

Answers

H + ions

Acidic and alkaline solutions can conduct electricity because they have ions that are free to carry charge. Look at the formulae of these acids. They all contain H + ions. When an acid is diluted the concentration of H + ions is decreased and the pH increases towards 7.

An acid is a chemical that, when added to water, releases hydrogen (H+) ions. The  ion is found in all acids is Hion. Therefore, option B is correct.

What is an acid ?

A Brnsted-Lowry acid or Lewis acid is a molecule or ion that has the ability to donate a proton or establish a covalent bond with an electron pair.

An acid is a chemical that, when added to water, releases hydrogen (H+) ions. A hydrogen ion is made up solely of a proton. The formulations for many acids may all be found to contain at least one H, such as hydrochloric acid.

The word "acid," which refers to the sour flavor and pungent odor of numerous acids, derives from the Latin word acidus, which meaning "sour." Examples: Because acetic acid and water are diluted, vinegar has a sour flavor.

Thus, option B is correct.

The skydiver will soon open her parachute. How will her velocity change when
the parachute first opens?

Answers

Answer:

How will her velocity change when  does parachute first open?

The skydiver's weight is balanced by the air resistance. There is no resultant force and the skydiver reaches terminal velocity. When the parachute opens, the air resistance increases. The skydiver slows down until a new, lower terminal velocity is reached.

When a skydiver opens their parachute, they accelerate upwards. This is not the same as saying the move upwards. Acceleration is a change in velocity. They keep feeling an upward force (while moving downward) that slows them until they get to a new terminal velocity.

What force changes when a parachute opens?

An open parachute increases the cross-sectional area of the falling skydiver and thus increases the amount of air resistance which he encounters (as observed in the animation below). Once the parachute is opened, the air resistance overwhelms the downward force of gravity.

What happens if you open the parachute too early?

You are likely to drift off the drop zone. The winds can be pretty heavy at high altitudes, and unless you steer continuously they may blow you off-course. Needless to say, the refrigeration effect of the wind and slipstream will make you feel even colder than the mere altitude. Your landing is likely to be rough.

What is molecular geometry?

Molecular geometry can be defined as a three -dimensional arrangement of atoms which constitute the molecule.It includes parameters like bond length,bond angle and torsional angles.

It influences many properties of molecules like reactivity,polarity color,magnetism .The molecular geometry can be determined by various spectroscopic methods and diffraction methods , some of which are infrared,microwave and Raman spectroscopy.

They provide information about geometry by taking into considerations the vibrational and rotational absorbance of a substance.Neutron and electron diffraction techniques provide information about the distance between nuclei and electron density.

Answers

Answer:

35.45253819

Explanation:

(0.7578*34.96....)+(0.2422*36.96...)

Relative and average atomic mass both describe properties of an element related to its different isotopes. Out of these two Relative atomic mas is more accurate. The average atomic mass of Chlorine is 35.45g.

What is mass?

Mass defines the quantity of a substance. It is measured in gram or kilogram. Average mass is the mass of atoms of an element that are isotopes. It can be calculated by multiplying mass of a isotope to natural abundance of that isotope.

Average atomic mass = (mass of first isotope× percent abundance of first isotope)+(mass of second isotope× percent abundance of second isotope)

Substituting the given values

Average atomic mass=(0.7578×34.96....)+(0.2422×36.96...)

Average atomic mass=35.45g

Therefore, the average atomic mass is 35.45g.

Answer to the correct number of sigtigs including units in your answer.
(to receive full credit, work must be submitted for this question)

Answers

Answer:

153.6771 amu

Explanation:

From the question given above, the following data were:

Isotope A:

Mass of A = 114.3789 amu

Abundance (A%) = 64.23%

Isotope B:

Mass of B =.?

Abundance (B%) = 100 – A%

Abundance (B%) = 100 – 64.23

Abundance (B%) = 35.77%

average atomic mass of Element Y = 128.4359 amu

The mass of the 2nd isotope (i.e isotope B) can be obtained as follow:

Average atomic mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100]

128.4359 = [(114.3789 × 64.23)/100] + [(Mass of B × 35.77) /100]

128.4359 = 73.4656 + (Mass of B × 0.3577)

Collect like terms

128.4359 – 73.4656 = Mass of B × 0.3577

54.9703 = Mass of B × 0.3577

Divide both side by 0.3577

Mass of B = 54.9703 / 0.3577

Mass of B = 153.6771 amu

Therefore, the mass of the 2nd isotope is 153.6771 amu

what is one way that the thermal energy of a system may be changed?

Answers

Answer:

In a open system, the thermal energy of a system may be changed by adding or removing matter with a different temperature.

Explanation:

The thermal energy of a system can be changed when a new substance of different temperature is introduced into the system

The thermal energy of a system is the amount of heat energy contained in that system.

The quantity of heat in a system is given as;

[tex]Q = mc \Delta \theta[/tex]

where;

[tex]\Delta \theta[/tex] is the change in the temperature of the system

When a new substance is introduced into the system, the temperature of the resulting system changes.

For example;

a hot iron introduced into a cold water, will increase the temperature of the water thereby increasing the thermal energy of the water.

Thus, the thermal energy of a system can be changed when a new substance of different temperature is introduced into the system.
