Which is thicker a 7mm or 9mm pencil lead?
A 9mm pencil lead is thicker than a 7mm pencil lead.
Thickness of a pencil?
A Pencil has a thickness of about 7 milimeters (mm).
How thick did a pencil used to be?
Historically, pencils were made with a diameter of around 7-8mm. Nowadays, standard-sized pencils typically have a diameter of 6-7mm.
What is the diameter of a diamond?
The diameter of a diamond can vary based on its shape and size. However, for a round brilliant cut diamond, the diameter is typically measured from point to point across the widest part of the diamond, known as the "girdle." Sizes can range from a few millimeters for smaller diamonds to over 10 millimeters for larger ones.
How far from source can light be seen if a 100W source radiates 600 nm light uniformly all directions and human eye can detect the light if 20 photons per sec enter dark eye with 7mm diameter pupil?
This is a complicated problem. But I can do it !Energy of single photon energy = (h) (c) / (wavelength) = (6.626 x 10-34 J-s) (299,792,458 m/s) / (600 x 10-9 m)= 3.3107 x 10-19 JouleThe eye requires 20 photons per sec = 6.6214 x 10-18 watt.The ratio of the required power to the power of the source is the ratio of the area of a 7mm circleto the area of the big sphere centered on the source.(6.6214 x 10-18) / (100) = (pi x 0.00352) / (4 pi R2)R2 = (100) (pi x 0.00352) / (4 pi x 6.6214 x 10-18)R = (5 x 0.0035) / (sqrt(6.6214) x 10-9)= 0.0068 x 109 = 6.8 x 106 meters= 6,800 km (4,225.8 miles)Wow !
Which is thicker a 5mm or 7mm pencil lead?
A 7mm pencil lead is thicker than a 5mm pencil lead. The diameter of the lead determines its thickness, so the lead with a larger diameter will be thicker.
Which is thicker a 7mm or 9mm pencil lead?
A 9mm pencil lead is thicker than a 7mm pencil lead.
Is 7mm larger than 5mm?
Yes, 7mm is larger than 5mm. The numerical value of 7 is greater than 5, indicating that 7mm is a larger measurement than 5mm. In terms of size and length, 7mm would be longer than 5mm.
Would 5mm be bigger than 7mm or smaller?
5mm is smaller than 7mm. In the metric system, the measurement is straightforward: the number indicates the size in millimeters, so 5 is less than 7. Therefore, 7mm is larger than 5mm.
What pen writes finer .5mm or .7mm?
.5mm is finer than .7 mm
Is a 7 mm mechanical pencil the same as a number 2 pencil?
The "number 2" designation refers to the "hardness" of the lead. The higher the number, the "harder" The "7mm" designation refers to the "thickness" of the lead. The higher the number, the thicker. They are not the same pencil.
What is an example of 7mm?
An example of 7mm is the diameter of a typical pencil lead, which is often around this measurement. Additionally, 7mm can refer to the size of various small caliber ammunition, such as the 7mm Remington Magnum used in hunting rifles. In the context of photography, 7mm can also describe a focal length for certain wide-angle lenses.
What is the range of 2mm 2mm 5mm 7mm?
It is 7 mm - 2 mm = 5 mm.
What is example of 7mm in size?
A common example of 7mm in size is a standard pencil lead, which typically measures around 0.7mm in diameter. Another example is the thickness of a credit card, which is approximately 0.76mm, making it slightly thicker than 7mm. Additionally, 7mm can refer to a small bolt or screw size used in various hardware applications.
Things that are 7mm long?
Objects that are approximately 7mm long include a standard pencil lead, which typically measures around this length, and the diameter of a small button. Additionally, some types of seeds, like those from certain grasses, can also be about 7mm. In the realm of technology, a 7mm long microchip or component may be found in various electronic devices.
Thickness of a pencil?
A Pencil has a thickness of about 7 milimeters (mm).
Could you draw a 7 millimeter line?
Yes. Its small obviously, but at just over half a centimetre, it is definitely a line!! =D Yes. Do you want a line 7mm in lenght or a line that is 7mm wide (many writing pens draw lines that are 5mm & 7mm wide).
