Un deportista de 72 kg trepa por una cuerda hasta una altura de 12m. Calcula el incremento de energía potencial gravitatoria que
Oxana [17]

A 72 kg athlete climbs a rope to a height of 12m. Calculate the increase in gravitational potential energy it has experienced.

Answer:

8467.2J

Explanation:

Given parameters:

Mass of the athlete = 72kg

Height of the climb  = 12m

Unknown:

Increase in gravitational potential energy it has experienced = ?

Solution:

Gravitational potential energy is the energy due to the position of a body. It is mathematically expressed as;

  Gravitational potential energy  = m x g x h

m is the mass

g is the acceleration due to gravity  = 9.8m/s²

h is the height

   Insert the parameters and solve;

  Gravitational potential energy  = 72 x 9.8 x 12

  GPE = 8467.2J

As a real gas deviates from ideal gas behavior, the particles _____
Alik [6]

Answer:

Have some attraction towards each other

Explanation:

Gases deviate from the ideal gas behavior because their molecules have forces of attraction between them. At high pressure, the molecules of gases are very close to each other so the molecular interactions start operating and these molecules do not strike the walls of the container with full impact.

Hope this helps :-)

Have a great rest of your day or night!

Scientists use scientific notation to communicate extremely small measurements. Hence, option A is correct.

<h3>What scientific notation?</h3>

Scientific notation is a way of writing very large or very small numbers.

Scientists use scientific notation to represent very small or very large numbers because this notation increases the  

  • accuracy of measured quantities.

  • convenience in using the numbers.

  • the number of significant figures.

  • precision of measurements.

Hence, option A is correct.

What mass of calcium carbonate is produced from 5.11<br> mol of sodium carbonate?
a_sh-v [17]

Answer:

There is 541.6 grams of calcium carbonate produced from 5.11 moles

Explanation:

Step 1: Data given

Number of moles of sodium carbonate ( Na2CO3) = 5.11 moles

Molar mass of sodium Carbonate:

⇒ Molar mass of Sodium = 22.99 g/mole

⇒ Molar mass of Carbon = 12.01 g/mole

⇒ Molar mass of Oxygen = 16 g/mole

Molar mass of Na2CO3 = 2* 22.99 + 12.01 + 3*16 = 105.99 g/mole

Step 2: Calculate mass of 5.11 moles of sodium carbonate

mass = number of moles of sodium carbonate * Molar mass of sodium carbonate

mass = 5.11 moles * 105.99 g/moles = 541.6 grams ≈ 542 grams

There is 541.6 grams of calcium carbonate produced from 5.11 moles Na2CO3
