What would indicate that a physical change takes place when copper is drawn into wire? Copper is heated, changing its molecular

structure. Copper is reshaped, but its molecular structure does not change. A new substance is formed that helps in drawing copper wire. Copper changes its color when drawn into wire.

How does the muscular system work with the respiratory system?
djverab [1.8K]

Answer:

The muscular and nervous systems enable the involuntary breathing mechanism. The main muscles in inhalation and exhalation are the diaphragm and the intercostals (shown in blue), as well as other muscles. Exhalation is a passive action, as the lungs recoil and shrink when the muscles relax.

The volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.

<h3>How to calculate volume?</h3>

The volume of a given gas can be calculated using the following Charle's law equation:

V1/T1 = V2/T2

Where;

  • T1 = initial temperature
  • T2 = final temperature
  • V1 = initial volume
  • V2 = final volume

  • V1 = 9L
  • V2 = ?
  • T1 = 325K
  • T2 = 450K

9/325 = V2/450

325V2 = 4050

V2 = 4050/325

V2 = 12.46L

Therefore, the volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.

Problem: If you push an object with a constant force of 100 N over a 10-meter distance. How much energy transfer occurs on the o
Sveta_85 [38]

The energy transferred on the object is 1000 Joules.

Given:

An object on which a constant force of 100 N was applied to displace it over a distance of 10 meters.

To find:

The energy transfer occurs on the object.

Solution

The force applied on the object = F = 100 N

The displacement of the object = d = 10 m

The energy transferred on the object or work done is given by:

W = F\times d\\W=100 N\times 10 m = 1,000 J

The energy transferred on the object is 1000 Joules.
