Answer: Astrology

Astrology is the study of the position and movement of planets, sun, moon and stars which affect the lives and character of an individual. It claims to predict the future events of the living individual as well as the natural events that may occur in it's surrounding environment. The roots of astrology comes from calendrical systems which can help in predicting the seasonal shifts and to interpret the celestial cycles of the objects in space.

When a wave is absorbed by a medium, its energy is transferred to the medium. The energy is most often transformed into thermal
Ad libitum [116K]

Answer:

TEMPERATURE

Explanation:

When a wave is absorbed by a material medium, different phenomena occur, but the collisions with the other particles causes the energy to be transformed into internal energy in the atoms and molecules of the material, with TEMPERATURE measurements the increase in the internal energy of the material.

A solenoidal coil with 25 turns of wire is wound tightly around another coil with 300 turns. The inner solenoid is 25.0 cm long
joja [24]

Answer:

5.65487\times 10^{-8}\ Wb

1.17\times 10^{-5}\ H

-0.020475 V

Explanation:

\mu_0 = Vacuum permeability = 4\pi \times 10^{-7}\ H/m

N_1 = Number of turns of coil  = 25

N_2 = Number of turns of coil 2 = 300

\frac{di_2}{dt} = Rate of current increased = 1.75\times 10^3\ A/s

d = Diameter = 2 cm

r = Radius = \frac{d}{2}=\frac{2}{2}=1\ cm

A = Area = \pi r^2

Magnetic field in the solenoid is given by

B=\mu_0\frac{N_2}{l}I\\\Rightarrow B=4\pi\times 10^{-7}\frac{300}{0.25}\times 0.12\\\Rightarrow B=0.00018\ T

Magnetic flux is given by

\phi=BA\\\Rightarrow \phi=0.00018\times \pi\times 0.01^2\\\Rightarrow \phi=5.65487\times 10^{-8}\ Wb

The average magnetic flux through each turn of the inner solenoid is 5.65487\times 10^{-8}\ Wb

Mutual inductance is given by

L=\frac{N_1\phi}{i_1}\\\Rightarrow L=\frac{25\times 5.65487\times 10^{-8}}{0.12}\\\Rightarrow L=1.17\times 10^{-5}\ H

The mutual inductance of the two solenoids is 1.17\times 10^{-5}\ H

Induced emf is given by

V=-L\frac{di_2}{dt}\\\Rightarrow V=-1.17\times 10^{-5}\times 1.75\times 10^3\\\Rightarrow V=-0.020475\ V

The emf induced in the outer solenoid by the changing current in the inner solenoid is -0.020475 V

In the produce section of a supermarket, five pears are placed on a spring scale. The placement of the pears stretches the sprin
tankabanditka [31]

Answer:

The displacement of the spring due to weight is 0.043 m

Explanation:

Given :

Mass m = 2 Kg

Spring constant k = 450 \frac{N}{m}

According to the hooke's law,

  F = -kx

Where F = force, x = displacement

Here,

F = mg         ( g = 9.8 \frac{m}{s^{2} } )

F = 2 \times 9.8 = 19.6 N

Now for finding displacement,

  x = \frac{F}{k}

Here minus sign only represent the direction so we take magnitude of it.

  x = \frac{19.6}{450}

  x = 0.043 m

Therefore, the displacement of the spring due to weight is 0.043 m
