<span>As in all the solids, their atoms are arrange in certain intermolecular distances. When the pressure in the solid, it changes this intermolecular distances which causes selectively changes all those effects which are associated with the interactions between molecules. Pressure changes the phonon frequencies, changes in phonon line shape in the solid. This is also responsible for change in melting and boiling points. The pressure may also cause for phase transition in many solids.</span>

IRISSAK [1]

Ans: <span>Alcohol addiction occurs when the desire to feel good and have the pleasurable feelings associated with alcohol or other drug drives desire to continue using the substances.
This is because when a person consumes alcohol on a daily basis, that person then becomes dependent on alcohol and then in every mood of happiness or anxiety, he/she has a strong desire of consuming alcohol and feel good after consuming it.</span>

Final speed after collision with the wall

$v_f = -0.4 m/s$

before collision the speed of ball initially

$v_i = 0.6 m/s$

time taken for the collision

$\Delta t = 0.2 s$

now as per the formula of acceleration we know that

$a = \frac{v_f - v_i}{\Delta t}$

now plug in all values in it

$a = \frac{-0.4 - 0.6}{0.2}$

$a = -5.0 m/s^2$

so acceleration is - 5 m/s/s for above situation

Two circular coils are concentric and lie in the same plane. The inner coil contains 110 turns of wire, has a radius of 0.014 m,

Hatshy [7]

Answer:

The current flowing through the outer coils is

Explanation:

From the question we are told that

The number of turn of inner coil is $N _i = 110 \ turns$

The radius of inner coil is $r_i = 0.014 \ m$

The current flowing through the inner coil is $I_i = 9.0 \ A$

The number of turn of outer coil is $N_o = 160 \ turns$

The radius of outer coil is $r_o = 0.022\ m$

For net magnetic field at the common center of the two coils to be zero the current flowing in the outer coil must be opposite to current flowing inner coil

The magnetic field due to inner coils is mathematically represented as

$B_i = \frac{N_i \mu I}{2 r_i}$
