Are the forces on the parachutes balanced?

A. The parachutes fall at a constant speed, so the forces are balanced.
B. There is a change in motion, so the forces are balanced.
C. The parachutes fall at a constant speed, so the forces are unbalanced.
D. There is a change in motion, so the forces are unbalanced.

Answers

Answer:

When the parachute opens, air resistance becomes much greater than gravity. The forces are no longer balanced and this changes her speed.

Explanation:

Eventually the upward force of the air equals the downward force of gravity. When forces are balanced the speed remains constant.

Answer:

Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light. ... So, Maxwell's equations do say that light is a wave.

What type of rock is limestone? Describe how a limestone rock is likely to change over a long period of time.

Answers

Answer:

Over time, the limestone is broken down into its chemical parts and may come back to the surface as volcanic CO2 (in the atmosphere). From the atmosphere, the CO2 might again become part of the biosphere by molluscs or corals absorbing the CO2 to help make their shells

Explanation:

Over a long period of time, we would take a look at the rock "limestone" through the rock cycle. Limestone being a sedimentary rock would be converted to marble, a metamorphic rock if subjected to metamorphic conditions over an extensive period of time.

Answers

Answer:

See answer below

Explanation:

To understand this, we need to make the reaction involved with the given configuration. Configuration R means that the substituents of the molecule, the priority order goes clockwise (From heaviest to lightest) so, if an Sn2 is ocurring in the reaction this means that the nucleophile, which in this case, is the sodium ethoxide will attack the molecule in the opposite side of the leaving group (which is the chlorine).

Also when this occurs, as Sn2 is a bimolecular reaction and is held in one step, it occurs an inversion in the configuration of the product. So, it's the innitial reactant was R, then the final product will be S.

A 475 cm3 sample of gas at standard temperature and pressure is allowed to expand until it occupies a
volume of 600. cm3. What temperature would be needed to return the gas to standard pressure?

Answers

The final temperature : 345 K

Further explanation

Given

475 cm³ initial volume

600 cm³ final volume

Required

The final temperature

Solution

At standard temperature and pressure , T = 273 K and 1 atm

Charles's Law  :

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]

Input the value :

T₂=(V₂T₁)/V₁

T₂=(600 x 273)/475

T₂=345 K

The law of conservation of mass indicates the same amount of glucose will be found in the reactants as in the
products
O The law of conservation of energy indicates the same amount of glucose will be found in the reactants as in the

Answers

Answer:

The law of conservation of mass indicates the same amount of carbon will be found in the reactants as in the  products

Explanation:

The reaction between carbon dioxide and water in the presence of sunlight to produce glucose and water strictly follows the law of conservation of mass.

Let us give the reaction expression:

        6CO₂   +   6H₂O   →   C₆H₁₂O₆   +    6O₂

According to the law of conservation of mass, matter is neither created nor destroyed but new compounds are formed during a chemical reaction.

From the given reaction expression, we can clearly see that 6 moles of carbon on the reactant side will produce 6 moles of carbon on the product side.

Therefore, the law obeys the law of conservation of mass.

Answer:

2.99 atm

2279.43 torr

44.07 psi

Explanation:

Torr, atms and psi all units are units of pressure.

Conversion from KPa to atm:

1 KPa is equal to 0.00987 atm. To convert from KPa to atm we will multiply the  given value with 0.00987 atm.

303.9 KPa × 0.00987 atm / 1 KPa

2.99 atm

Conversion from KPa to torr:

1 KPa is equal to the 7.5006 torr. To convert from KPa to torr we will multiply the KPa value by 7.5006.

303.9 KPa × 7.5006 torr/ 1 KPa

2279.43 torr

Conversion from KPa to psi:

psi is pound per square inch. 1 KPa is equal to the 0.1450 psi. To convert from KPa to psi we will multiply the KPa value by 0.1450 psi.

303.9 KPa × 0.1450 psi /  1 KPa

44.07 psi
