It is 30/4 = 7.5
The "diameter" is the maximum width of a circle. It is not a fixed unit of length.
Well it is not a fixed ratio, each element has its own diameter for the atom and nucleus depending on atomic number and atomic weight. but an idea can be given: for a certain elemnt the atom daimeter is 225 picometer and the nucleus diameter is 6 femtometer ,the ratio would be ( 225x 10^ - 12) /(6x 10^ - 15)= 37500.
A solid figure that has 2 parallel bases that are congruent circles. A Cylinder is a solid figure described by the revolution of a rectangle about one of its sides which remains fixed. Two ends of a cylinder are the circles of same diameter. Examples include pipes, cans, and poles. cylinder?

Here's a guess... Without getting overly complicated.... The diameter of the atom isn't just the diameter of the atom's nucleus... it is the diameter of the whole atom including the electron cloud surrounding the nucleus. As the name implies, an electron cloud represents all the possible locations that the electron could be. This cloud has thickness and therefore the atom could be smaller if the electron is in a portion of the cloud closer to the nucleus or larger is the electron is in a portion of the cloud farther from the nucleus. The "known value" is probably just the average of the two. Therefore, an atom's diameter has a range rather than a fixed value.
Pi is a number that occurs in many areas of mathematics. It is a number which has a value of approximately 3.1416. With respect to a circle, pi is the ratio between the circumference and the diameter of a circle.
The ideal (not idea) mechanical advantage is 30/4 = 7.5
' 1 ' is.
Mechanical advantage of a fixed pulley
yes
A fixed pulley does NOT multiply the effort force or have a mechanical advantage. It only changes the direction of the effort force. A free pulley multiplies the effort by two. this means the free pulley has a mechanical advantage of 2.information from:www.mhscience02.com
Single fixed pulley
A single fixed pulley (:
no it does not,it has no mechanical advantage whatsoever. It is just an advantage because it goes in the opposite direction in which you pull.
Thew pulley changes the direction of the effort force.
Because it has a low input force
Fixed Pulley!!
The mechanical advantage would be 1 because the force required to life the mass of an object becomes 1/2 the original weight of the object.
