The speed of sound in different materials:

• Air: 332 m/s
• Sea water: 1530 m/s
• Lead: 2160 m/s
• Gold: 3240 m/s
• Brick: 3650 m/s
• Copper: 4760 m/s
• Glass: 5100 m/s
• Aluminium: 6420 m/s

Explanation

Distribution Delay Line refers to a certain length of the actual transmission line that affects signal delay.

It describes how signal timing is influenced by the physical length of the transmission medium.

Explanation

Aluminium is capable of superconductivity, with a superconducting critical temperature of 1.2 kelvin

And a critical magnetic field of about 100 gauss (10 milliteslas)

It is paramagnetic and thus essentially unaffected by static magnetic fields

Explanation

Explanation

Work done (W) is given by:

W = F * d

where F is the force applied and d is the displacement.

Since the mass of the box is 2 kg and a force of 50 N is applied for 2 seconds, we can calculate the acceleration (a) using:

F = m * a

a = F / m

= 50 / 2

= 25 m/s²

The displacement (d) can be calculated using:

d = (1/2) * a * t²

where t is the time.

d = (1/2) * 25 * (2)²

= 50 m

Now, we can calculate the work done:

W = F * d

= 50 * 50

= 2500 J
