How is Diamond different from cubic Zirconia?

Physics
1 answer:
seraphim [82]2 years ago
4 0

Answer:

A diamond is the hardest stone known to man while a cubic zirconia has a much lower rating of hardness. Diamonds are made of carbon which lends to their brilliance and hardness. ... A diamond and a cubic zirconia can be the same in actual size, but cubic zirconias are slightly denser and will weigh more.

What is cardiovascular eficiencia
Minchanka [31]
English: Cardiovascular efficiency depends on a number of factors. One measure is called stroke volume, which is the volume of blood pumped per heartbeat. A fit individual has a larger stroke volume, which means a greater volume of oxygen is delivered to the body per heartbeat.

Spanish: La eficacia cardiovascular depende de una serie de factores. Una medida se denomina volumen sistólico, que es el volumen de sangre bombeada por latidos cardíacos. Un individuo en forma tiene un volumen de movimiento mayor, lo que significa que un mayor volumen de oxígeno es entregado al cuerpo por latidos cardíacos.

2. What is the resistance expected on a heater that is feed by 480V AC and the Electric Power is 4.6kW? ​
Korvikt [17]

The resistance expected of the heater is 50.1 ohms.

<h3>What is resistance?</h3>

Resistance can be defined as the opposition to the flow of electric current in an electric circuit. The S.I unit of resistance is Ohms (Ω).

To calculate the resistance of the heater, we use the formula below.

<h3>Formula:</h3>
  • R = V²/P............. Equation 1

Where:

  • R = Resistance of the heater
  • P = Power of the heater
  • V =  Voltage supplied to the heater

From the question,

Given:

  • V = 480 V
  • P = 4.6 kW = 4600 W

Substitute these values into equation 1

  • R = (480²)/4600
  • R = 50.1 ohms.

Hence, the resistance expected of the heater is 50.1 ohms.

Defined the work of vector​
cricket20 [7]

Answer:

In physics, work is the amount of energy required to perform a given task (such as moving an object from one point to another). We start by defining the scalar product of two vectors, which is an integral part of the definition of work, and then turn to defining and using the concept of work to solve problems.

Which statement is true about crystal lattice energy?
irinina [24]

The answer is:

It is a measure of the strength of the bonds between ions.

Lattice energy is an estimate of the strength of the bonds formed by ionic compounds.

The first two choices are wrong because it is actually the opposite.

  • As the ion size increases, lattice energy <u>decreases</u>.
  • As charge of ions increases, lattice energy <u>increases</u>

As for the other third option, it is wrong because lattice energy is the energy RELEASED not absorbed.
