Answer:
1) Measuring cylinder
2) Top Pan Balance
Explanation:
To find the density of the pebble Nabil should first accurately measure the mass of the pebble using the top pan balance
He should then fill the displacement can till the water reaches the outlet pipe at the to of the cylinder
He should then place the pebble into the cylinder carefully ans allow the water that would start coming out to stop
The volume of water in the displaced cylinder is then measured and the density is found by dividing the mass of the pebble by the volume of water in the measuring cylinder
<h2>Answer:</h2>
No, interference patterns will not be observed as the two sources of light are neither monochromatic neither coherent and therefore interference of light will not form total reinforcement or total cancellation at any point
Answer:
η = 0.7
Explanation:
The refractive index of the material can be calculated by using the following formula:
where,
η = refractive index of the material = ?
c = speedof light in vaccuum = 3 x 10⁸ m/s
v = speed of light in this material = 4.3 x 10⁸ m/s
Therefore,
<u>η = 0.7</u>
