q3 - I am not sure, sorry:(

q 4 - Alcoholism is a disease because it not only causes people to become addicted to alcohol, which has many harmful consequences such as heart disease, but it also causes people to relapse when they say they will stop drinking. However, some people who were addicted to alcohol realised during that time that life has a purpose and that being addicted to alcohol will not solve problems. This person's alcoholism inspired them to change their lives and mindsets, as well as to work on their goals, which has led them to accomplish many things in life.For example, celebrity Daniel Radcliffe, 29, acknowledged to using alcohol to cope with the immediate popularity he'd achieved as the lead of the Harry Potter films. Despite enjoying his work, the English actor claims he isolated himself from the public to avoid the constant attention. Radcliffe attributes his ability to get therapy and create new, better coping techniques to his close pals.

It remains the same

Explanation:

It remains the same. This is because the number of protons doesn't change and the number of protons determines the atomic number.

The frequency of the string if it had an 8 loop standing wave pattern is determined as 13.4 Hz.

The relationship between number of loops and harmonics of the standing wave is given as follows;

Frequency of the string if it had an 8 loops standing wave pattern

f₄ = 4f₁

f₁ = f₄/4

f₈ = 8f₁

f₈ = 8(f₄/4)

f₈ = 2f₄

f₈ = 2 x 6.7 Hz

f₈ = 13.4 Hz

Thus, the frequency of the string if it had an 8 loop standing wave pattern is determined as 13.4 Hz.

Hi there!

We can begin by finding the equivalent resistance of the parallel segment shown in the diagram.
Recall the following for resistors in parallel:
[tex]\frac{1}{R_e} = \frac{1}{R_1} + \frac{1}{R_2} + ... + \frac{1}{R_n}[/tex]

Plug in the given values for the resistances and solve.

[tex]\frac{1}{R_e} = \frac{1}{40} + \frac{1}{20}\\\\\frac{1}{R_e} = 0.075\\\\R_e = \frac{1}{0.075} = 13.333 \Omega[/tex]

Now, to solve for the total voltage that will go through this segment, we can use Ohm's Law:
[tex]V = iR\\\\V = 1.2 (13.333) = 16 V[/tex]

This is a parallel branch, so 16V goes through each resistor. We can now rearrange Ohm's law equation to solve for current for each resistor.

[tex]i = \frac{V}{R}\\\\i_{40} = \frac{16}{40} =\boxed{ 0.4 A}\\\\i_{20} = \frac{16}{20} = \boxed{0.8 A}[/tex]

**Notice that the two currents ADD UP in parallel to the total. Also, this problem can be done more simply using ratios, but this method will help you solve series and parallel combination circuits.

He had pushed the bag with his leg

The object was moving at constant velocity between the points on the graph that we marked 6 s to 8s.

The term acceleration has to do with the change of velocity with time. In this case, we saw that the velocity of the car was not changed between 6 s to 8s.

Now , the object was moving at constant velocity between the points on the graph that we marked 6 s to 8s.

The time taken, and the distance travelled by the car before stop, will be 5.3 second and -53.3 m west.

The length of the path traveled by the body is known as the distance covered by the body.

Distance is a 1-dimensional phenomenon. its unit is a meter(m). The distance can be found by the product of velocity and time.

The given data in the problem will be

u is the initial velocity =20m/sec

t is the time =?

d is the distance =?

From the Newtons second law;

[tex]\rm F \triangle t = \triangle P \\\\ \triangle t = \frac{\triangle P }{F} \\\\ \triangle t = \frac{m(v_f-v_i)}{F} \\\\ \ \triangle t = \frac{2240 (0-20))}{8410} \\\\ \triangle t = 5.3 \ sec \\\[/tex]

The distance travelled before the car stop is,

[tex]\rm \triangle t = \frac{1}{2} (v_f+v_i)\traingle t \\\\ \traingle x = \frac{1}{2} (-20+0)5.3 \\\\\ \triangle x= -53.3 m \ west[/tex]

Hence,the time taken, and the distance travelled by the car before stop, will be 5.3 second and -53.3 m west.
