Gravitational potential energy is a function of the _____ and the ________ of an object.
babymother [125]

Answer:

B = mass, height

Gravitational potential energy is a function of the mass ans the height of an object.

Explanation:

The formula for gravitational potential energy is

GPE = mgh

m = mass in kilogram

g = acceleration due to gravity

h = height in meter above the ground

Formula:

GP.E = mgh

Consider the following example:

A crane lifts a 75kg mass a height of 8 m. Calculate the gravitational potential energy  gained by the mass:

Formula:

GP.E = mgh

Now we will put the values in formula.

g = 9.8 m/s²

GP.E = 75 Kg × 9.8 m/s²× 8 m

GP.E = 5880 Kg.m²/s²

Kg.m²/s² = j

GP.E = 5880 j

When circumstances are right, most materials undergo a process called thermal expansion. Which statement best describes the caus
harina [27]

Answer: Matter is heated, and its particles spread out more

Explanation:

Thermal expansion occurs when there's an expansion of an object or material or when an object becomes bigger because of a rise in its temperature. This brings about the faster movement of the heated molecules and the atoms spreading out.

Therefore, the cause and effect of thermal expansion will be that when matter is heated, and its particles spread out more.

In the following reaction, what is the effect of adding more NO2 to the starting reaction mixture?
Mars2501 [29]

Answer:

It would increase the final quantity of products

Explanation:

According to the Le- Chatelier principle,

At equilibrium state when stress is applied to the system, the system will behave in such a way to nullify the stress.

The equilibrium can be disturb,

By changing the concentration

By changing the volume

By changing the pressure

By changing the temperature

Consider the following chemical reaction.

Chemical reaction:

2NO₂ ⇄ N₂O₄

In this reaction the equilibrium is disturb by increasing the concentration of reactant.

When the concentration of reactant is increased the system will proceed in forward direction in order to regain the equilibrium. Because when reactant concentration is high it means reaction is not on equilibrium state. As the concentration of NO₂ increased the reaction proceed in forward direction to regain the equilibrium state and more product is formed.

which statement best describes a mole? it is 12 units of a given substance. it contains 6.02 1023 grams of sodium chloride. it i
Digiron [165]

Answer:

The correct option is;

It contains 6.02 × 10²³ particles of a given substance

Explanation:

A mole of substance is the standard scientific unit of measurement for the quantity of the substance which is made up of a large number of small particles such as molecules, ions, atoms, electrons or other entities.

The General Conference on Weights and Measures defines the mole as the amount of a substance that contains 6.02214076 × 10²³ units of entities

The number 6.02214076 × 10²³, is also known as Avogadro's number.
