It is allotroph of carbon so it shows metal properties
Answer:
The diameter of the moon's image is 0.31 cm.
Explanation:
Given that,
Focal length = 34.3 cm
Diameter of the moon
Mean distance from the earth
At that distance the object is assumes to be at infinity. hence the image will be formed at a distance equal to focal length
So, the image distance is 34.3 cm.
We need to calculate the diameter of the moon's image
Using formula of magnification
Hence, The diameter of the moon's image is 0.31 cm.
Multiply 25 times 6, to get 60 seconds and that is your beats per minute. In this case it is 150 BPM.
Answer:
(a): Linear charge density of the circular arc =
(b): Surface charge density of the circular arc =
(c): Volume charge density of the sphere =
Explanation:
<h2><u>
Part (a):</u></h2>
<u>Given:</u>
- Total charge on the circular arc,
- Radius of the circular arc,
- Angle subtended by the circular arc,
We know, e is the elementary charge whose value is
Therefore,
Also, the length l of a circular arc is given as:
The linear charge density of the arc is defined as the charge per unit length of the arc.
<h2><u>
Part (b):</u></h2>
<u>Given:</u>
- Total charge on the circular disc,
- Radius of the circular disc,
Surface area of the circular disc,
The surface charge density of the disc is defined as the charge per unit area of the disc.
<h2><u>
Part (c):</u></h2>
<u>Given:</u>
- Total charge on the sphere,
- Radius of the sphere,
Volume of the sphere,
The volume charge density of the sphere is defined as the charge per unit volume of the sphere.
