Where do most stars fall on the Hertzsprung-Russell diagram?

Physics
1 answer:
Alex_Xolod [135]2 years ago
7 0

Answer:

Most of the stars occupy the region in the diagram along the line called the main sequence. During the stage of their lives in which stars are found on the main sequence line, they are fusing hydrogen in their cores.

A cube 6.0 cm on each side is made of a metal alloy. After you drill a cylindrical hole 2.0 cm in diameter all the way through a
Crank

To solve this problem it is necessary to apply the concepts related to Newton's second law, the definition of density and the geometric relationships that allow us to find the volume of the figures presented.

For the particular case of the Cube with equal sides its volume is determined by

V_c = l^3

V_c = 6^3 = 216cm^3

In the case of perforated material we have that its volume is given according to the cylindrical geometry, that is to say

V_d = \pi r^2*l

V_d = \pi (\frac{2}{2})^2*6

V_d = 6\pi cm^3

In this way the net volume would be

\Delta V = V_c-V_d

\Delta V = 216cm^3-6\pi cm^3

\Delta V = 197.15cm^3 = 197.15*10^{-6}m^3

We need to find the mass, but we have the Weight and Gravity so from Newton's second Law

F= mg

m = \frac{F}{g}

m = \frac{6.6}{9.8}

m = 0.673kg

PART A) From the relation of density as a unit of mass and volume we have to

\rho = \frac{m}{V}

\rho = \frac{0.673}{197.15*10^{-6}}

\rho = 3413.64kg/m^3

PART B) To find the weight of the cube then we apply the ratio of

W = mg

W = V\rho g

W = (216*10^{-6})(3413.64)(9.8)

W = 7.22N

One hundred turns of (insulated) copper wire are wrapped around a wooden cylindrical core of cross-sectional area 1.32 × 10-3 m2
kenny6666 [7]

Answer:

The charge flos through the coil is 0.023C

Explanation:

To solve this problem, it is necessary to apply the concepts related to Faraday's Law in which it is possible to calculate the emf Voltage induced due to a charge in a magnetic field

and Ohm's Law for the calculation of the current based on a given load over time.

Our data are given by:

N=100

A= 1.32*10^{-3}m^2

R=15\Omega

Where

N is the number of loops, A the area and R the Resistance.

The change in magnetic field can be calculated as,

dB = 1.31-(-1.31)

dB = 2.62T

The Faraday's law of electromagnetic induction is given by definition as,

V = NA \frac{dB}{dt}

In the other hand Ohm's law says:

V = IR

V = \frac{dq}{dt} R

Equating both equations we have

\frac{dq}{dt} R = NA \frac{dB}{dt}

We can re-arrange the equations to solve q, then

dq = \frac{NA(dB)}{R}

q = \frac{(100)(1.32*10^{-3})(2.62)}{15}

q = 0.023C

Therefore the charge flos through the coil is 0.023C
