Warming signs before fad diet includes:

1. When a special type of diet is recommended for weight loss.

2. When quick weight loss is promised instead of advice on the need to exercise, eat healthy foods including fruits and vegetables, and adopt a good feeding behavior.

3. Promises rapid weight loss in a short period of time.

After taking the fad diet the following might be experienced:

1. Constipation.

2. Weakness and fatigue.

3. More accumulation of fats in the body in the long run after a short term normal  BMI (Body mass index).

4. Lower metabolic rates over time.

Explanation:

weight loss is a practice adopted by people for various reasons ranging from the desire to stay healthy to, ability to pursue a career that requires a good Body Mass Index. For instance, A BMI (Body mass index) which is equal to a person's weight (kg) / (height(m))^2 of 30 and higher is considered obese.

Fad diet which may give a temporary result of weight loss is not considered totally healthy as it doesn't capture the need to eat a healthy balanced diet instead focuses on more routine consumption of a particular kind of diet.

A healthy weight loss plan captures the need to exercise, reduce body fats while eating healthy. Eating fruits, vegetables are also encouraged.

If the change in velocity increases, the acceleration during the same time period increases as well. The correct option is B.

Electric current is the flow of electric charge through a conducting material, such as a wire. It is measured in units of amperes (A), which represents the rate of flow of electric charge.

The standard definition of electric current is that it is the amount of electric charge passing through a given area of a conductor in unit time.

Mathematically, electric current is expressed as:

I = Q / t

Where

I = the electric current,

Q =the amount of electric charge that flows through a conductor,

t = the time interval during which the charge flows.

The unit of electric charge is coulombs (C), which represents the charge carried by a current of one ampere flowing for one second. So, one ampere of electric current represents a flow of one coulomb of electric charge per second.

Electric current is typically measured using an ammeter, which is a device that is inserted in series with a circuit to measure the current flowing through it. The ammeter is designed to have very low resistance, so it does not significantly affect the current flowing through the circuit being measured.

Here in the question,

If the change in velocity increases, the acceleration during the same time period increases as well. This is because acceleration is directly proportional to the change in velocity over time, as expressed by the formula:

a = (v_f - v_i) / t

Where

a = acceleration,

v_f = the final velocity,

v_i = the initial velocity,

t = the time interval during which the velocity changes.

If the change in velocity is greater, the numerator of the equation is larger, and therefore, acceleration is greater. Similarly, if the time interval is kept constant, an increase in velocity change leads to an increase in acceleration.

Therefore, when velocity increases the acceleration also increases.

Answer:

b. -1.5 m/s²

Explanation:

Given the following data;

Initial velocity = 15m/s

Time = 10 seconds.

Since the car came to rest, final velocity = 0m/s

To find acceleration;

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of final speed from the initial speed all over time.

Mathematically, acceleration is given by the equation;

[tex]Acceleration (a) = \frac{initial \; speed - final \; speed}{time}[/tex]

[tex]a = \frac{v - u}{t}[/tex]

Where,

a is acceleration measured in [tex]ms^{-2}[/tex]

v and u is initial and final speed respectively, measured in [tex]ms^{-1}[/tex]

t is time measured in seconds.

Substituting into the equation, we have;

[tex] Acceleration, a = \frac{0 - 15}{10}[/tex]

[tex] Acceleration, a = \frac{-15}{10}[/tex]

Acceleration = -1.5 m/s²

Answer:

[tex]375\ \text{kg m/s}[/tex]

Explanation:

[tex]m[/tex] = Mass of biker = [tex]75\ \text{kg}[/tex]

[tex]v[/tex] = Velocity of bike = [tex]5\ \text{m/s}[/tex]

Momentum is given by the product of mass and velocity so,

[tex]p=mv[/tex]

[tex]\Rightarrow p=75\times 5[/tex]

[tex]\Rightarrow p=375\ \text{kg m/s}[/tex]

The momentum of the biker is [tex]375\ \text{kg m/s}[/tex].

The biker's momentum will be "375 kg m/s".

The proportion or resultant of a subatomic particle mass as well as the speed. Momentum would be a vector quantity, which means it does have a magnitude and therefore an orientation or directions.

According to the question,

Biker's mass, m = 75 kg

Biker's velocity, v = 5 m/s

We know the relation,

Momentum = Mass × Velocity

or,

→ p = mv

By substituting the values, we get

      = 75 × 5

      = 375 kg m/s

Thus the above answer is correct.

Answer: C

Explanation:

The model which represents best of transverse wave with very high crests and low troughs is the third graph. Hence, option C is correct.

Sound is a physical perturbation from an equilibrium position that travels through an elastic medium of material. It is also possible to define sound solely subjectively, as that which is regarded by the ear, but this definition lacks clarity and is overly constrictive because it is useful to discuss sounds that are produced by devices other than the human ear, such as dog whistles and sonar hardware, which cannot be done here by the auditory system.

The characteristics of sound waves should be examined first in any study of sound. Transverse and longitudinal waves are the two fundamental forms of waves, and they differ by the direction wherein they move.

The first graph is uniform trough and crest, but the third one has higher crest but lower trough.

Answer:

1) Ex(P) = -8.34602 N/C

2) [tex]E_y(P)[/tex] = -5.23850174216 N/C

3) Question (3) is a similar question to (1)

4) [tex]E_y(P)[/tex] = -5.23850174216 N/C

5) [tex]\sigma _b[/tex] ≈ 1.041466 C/m²

6) σₐ ≈ 2.2330413 C/m²

Explanation:

The given parameter of the point charge located at the center of a conducting shell

The charge of the point charge, q₁ = -8.9 μC

The inner radius of the shell, a = 2.8 cm

The outer radius of the shell, b = 4.1 cm

The charge of the conducting shell, q₂ = 2.2 μC

Therefore, we have;

1) The point P(8.5, 0)

[tex]V = k \cdot \dfrac{q_1 + q_2 }{r^2}[/tex]

By plugging in the values, we have;

For

R₁ < R₂ < r, for the electric field at the point, 'P', we have;

[tex]E_x(P) = 9 \times 10^9 \times \dfrac{-8.9 \ \times 10^{-6} + 2.2 \ \times 10 ^{-6} }{(0.085 \ )^2} = -8.34602[/tex]

Ex(P) = -8.34602 N/C

2) For the point given with coordinates (8.5, 0), the distance of the y-component of point from the center = 0

The y-component of the electric field = 0 N/C

4) For r = 1.4 cm, along the y-axis we have;

R₁ < r < R₂

Therefore, we have;

[tex]E = k \cdot \left( \dfrac{q_1 }{r} + \dfrac{q_2}{R_2}\right)[/tex]

Substituting the values, we get;

[tex]E_y(P) = 9 \times 10^9 \times \left( \dfrac{-8.9 \times 10^{-6}}{0.014} + \dfrac{2.2 \times 10^{-6}}{0.041}\right) = -523850174216[/tex]

[tex]E_y(P)[/tex] = -5.23850174216 N/C

5) The charge density, [tex]\sigma _b[/tex], is given as follows;

[tex]\sigma_b = \dfrac{Q}{A} = \dfrac{2.2 \times 10^{-6} }{4\times \pi \times 0.041^2 } \approx 1.041466 \ C/m^2[/tex]

6) Similarly, we have;

[tex]\sigma_a = \dfrac{Q}{A_a} = \dfrac{2.2 \times 10^{-6} }{4\times \pi \times 0.028^2 } \approx 2.2330413 \ C/m^2[/tex]

Answer:

Weight = 88N

Explanation:

Given the following data;

Acceleration due to gravity on moon = 1.6m/s²

Weight on earth = 539N

To find the weight on moon.

First of all, we would calculate the mass;

Weight = mass * acceleration due to gravity.

We know that acceleration due to gravity on earth is equal to 9.8m/s²

Substituting into the equation, we have;

539 = mass * 9.8

Mass = 539/9.8

Mass = 55 kg.

Now, we solve for the weight on moon.

Weight = 55 * 1.6

Weight = 88N

The question that how many hours a day dolphins sleep requires the collection of data to answer it. Hence, option B is correct.

Dolphins are small-toothed cetaceans that are distinguished by their always open, curving mouths. Every ocean contains one of the 36 dolphin species. The majority of dolphins are marine mammals that inhabit the sea or coastal environments with brackish water. However, there are a few species that live in freshwater streams and rivers, including the South Asian river dolphin and the Amazon River dolphin, or boto.

The orca, the biggest dolphin, can reach lengths of more than 30 feet. The Maui dolphin, which is the smallest, is only five feet long.

Dolphins mostly consume fish and squid, which they can locate via echolocation, an inbuilt sonar system that reflects sound waves off prey to disclose details about its location, size, and shape. Up to a thousand clicking sounds can be heard every second from an echo locating bottlenose dolphin.
