A cylinder that is 15 cm tall is filled with water. If a hole is made in the side of the cylinder, 4.0 cm below the top level. Assume that the cylinder is large enough so that the level of the water in the cylinder does not drop significantly. 1) How far from the base of the cylinder will the stream land

About 13 cm

Explanation:

We are given that

Length of cylinder,l=15 cm=

1 m=100 cm

h=4 cm=

Horizontal velocity of the existing water stream=

Where

Using the formula

h'=l-h=15-4=11 cm=

Initial velocity of water stream,u=0

Distance, d=vt

Using the formula

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
