The atomic number is the number of protons. If the atomic number is 30, then the atom will have 30 protons.

Hi ;)
First of all, The number of protons is always equal to the number of electrons in a neutral atom.Since we have 30 protons and 30 electrons ,the positive charge on the proton is cancelled by the negative charge on the electron leaving a neutral atom.

Positive 30 and negative 30 equals 0.

Therefore , that atom would have 30 protons .

A student team is to design a human powered submarine for a design competition. The overall length of the prototype submarine is

Allushta [10]

Answer:

a) The speed is 61.42 m/s

b) The drag force is 10.32 N

Explanation:

a) The Reynold´s number for the model and prototype is:

$Re_{m} =\frac{p_{m}V_{m}L_{m} }{u_{m} }$

$Re_{p} =\frac{p_{p}V_{p}L_{p} }{u_{p} }$

Equaling both Reynold's number:

$\frac{p_{p}V_{p}L_{p} }{u_{p} }=\frac{p_{m}V_{m}L_{m} }{u_{m} }$

Clearing Vm:

$V_{m} =\frac{p_{p}V_{p}L_{p} u_{m} }{u_{p} p_{m} L_{m} }=\frac{999.1*0.56*8*1.849x10^{-5} }{1.138x10^{-3}*1.184*1 } =61.42m/s$

b) The drag force is:

$\frac{F_{Dm} }{p_{m}V_{m}^{2}L_{m}^{2} } =\frac{F_{Dp} }{p_{p}V_{p}^{2}L_{p}^{2} } \\F_{Dp} =\frac{F_{Dp}p_{p}V_{p}^{2}L_{p}^{2} }{p_{m}V_{m}^{2}L_{m}^{2} } \\F_{Dp}=\frac{2.3*999.1*0.56^{2} *8^{2} }{1.184*61.42^{2}*1^{2} } =10.32N$

In what stage do children see the world in an egocentric way?

zheka24 [161]

Answer: Preoperational stage (second stage).

Explanation: In the second stage of Child's development i.e., from the age of 2 years to 7 years approximately, which is called as Preoperational stage, a child develops a strong sense of Egocentrism. It is a situation where a child is unable to see thing from other peoples' eye and feels that everyone's reaction to something should be same as the child's. At this stage, a child is busy and completely trapped in his own dreamy world and is not ready to understand things properly.

Hence, the stage is Preoperational stage.

uppose that white light strikes a flat piece of flint glass in air, coming in at an angle of 60 degrees to the surface (30 degre

Elodia [21]

Answer:

Explanation:

Snell's law for index of refraction of a medium is as follows .

sin i / sin r = μ

i is angle of incidence , r is angle of refraction and μ is refractive index.

sin r = sin i / μ .

As μ for blue light is greatest , angle of refraction for blue light will be least . Similarly , angle of refraction will be maximum for red light .

So maximum deviation in the direction of light will occur in blue light due to least angle of refraction because

deviation angle = angle of incidence - angle of refraction .

So the order of light from inward towards surface

= blue , green , red .
