Answer:

B) caused by eating irregularly over short periods

Explanation:

Disordered eating refers to a range of irregular and unhealthy eating behaviors and attitudes toward food. Disordered eating is often C. a precursor for developing a disorder, but not a disorder on its own

Disordered eating refers to a range of irregular eating behaviors and attitudes towards food that may not meet the full diagnostic criteria for an eating disorder but still involve disturbances in eating patterns, body image, and weight. It can include behaviors such as restrictive eating, binge eating, purging, or excessive exercise.

While disordered eating shares similarities with eating disorders, it is considered a precursor or warning sign that someone may be at risk of developing a diagnosable eating disorder, such as anorexia nervosa, bulimia nervosa, or binge eating disorder. Disordered eating patterns can often progress and become more severe if left untreated, potentially leading to the development of an eating disorder.

Thereofre, disordered eating is often C. a precursor for developing a disorder, but not a disorder on its own.

Explanation:

(1) Given that,

A charge, [tex]q=3\times 10^{-7}\ C[/tex]

Electric field, E = 27 N/C

We need to find the force acting on the charge. The force on the charge is given by :

[tex]F=qE\\\\F=3\times 10^{-7}\times 27\\F=8.1\times 10^{-6}\ N[/tex]

So, the force acting on the charge is [tex]8.1\times 10^{-6}\ N[/tex]

(b) Charge, [tex]q=5\times 10^{-6}\ C[/tex]

Force, [tex]F=2\times 10^{-4}\ N[/tex]

Let E be the electric field.

[tex]E=\dfrac{F}{q}\\\\E=\dfrac{2\times 10^{-4}}{5\times 10^{-6}}\\\\E=40\ N/C[/tex]

So, the electric field is 40 N/C.

Answer:

its false

Explanation:

Answer:

a. 24 kg m/s

b.  3/5s

Explanation:

a.impulse is the change in momentum so at first the momentum is zero because the ball was at rest and the final momentum is 1.2kg*20m/s=24 kg m/s

so the impulse would be (24-0) kg m/s=24 kg m/s

b. so the impulse equation is impulse is force *delts time

so 24 kg m/s=40N*t

t=24 kg m/s /40N=3/5 s

the momentum = m * v

m : mass

v : velocity

momentum = 1 * 50 = 50 kg.m/s

It's not true, no. The weight can be used to calculate an object's product of mass, but not gravity. The object's mass is multiplied by gravity, as is evident. However, an object's mass will never be 0 and will always be constant, its weight would be zero if there is no gravity. Since mass and weight are not the same, the assertion is untrue.

Weight is the gravitational pull of a large second object, thus the Moon or the Earth, at the first object. Weight is a result of the universal law of gravity, according to which any two objects will gravitationally pull one another with a force exactly equal to the applied of their masses and divided by the square of a distance separating them.

Because of this, larger items naturally weigh more when placed in the same spot; yet, the farther any object seems to be from the Earth, the less weight it has.

Because of the tiny difference in size between the polar and equatorial radii of the Earth, an object's weight at the South Pole is somewhat higher than its value at the Equator.

Explanation:

this is because the neutrons do not have a charge, the things that have charge in an atom are electrons and protons.

and in the nucleus of an atom, there are protons and neutrons so you can see that A is not the answer

if you see the periodic table, you will know that the number of electrons and protons are equal, so the charges cancel each other out, hence the charge of an atom will be neutral

let me give you a tip which I got from my teacher, never write there is no charge in the atom, this suggests that there is no protons or electrons.

Answer:

a)   y = y₀ - 4.9, v = -9.8 m / s, b)  y =y₀ - 19.6,  v = - 19 m / s

c)  y =y₀ - 44.1, v = - 29.4 m / s

Explanation:

To solve this exercise let us use the kinematic relations

          y =y₀ + v₀ t - ½ g t²

          v = v₀ - g t

They indicate that the body is released therefore the initial velocity is zero v₀ = 0

          y = y₀ - ½ g t²

          v = - gt

a) the position and velocity for t = 1s

         y = y₀ - ½ 9.8 12

         y = y₀ - 4.9

         v = - 9.8 1

         v = -9.8 m / s

the negative sign indicates that the velocity is directed downwards

b) t = 2 s

         y =y₀ - ½ 9.8 2 2

         y =y₀ - 19.6

         v = - 9.8 2

         v = - 19 m / s

c) t = 3 s

        y = y₀ - ½ 9.8 3 2

        y =y₀ - 44.1

        v = - 9.8 3

        v = - 29.4 m / s

Answer:

Weight and reaction.

Explanation:

With respect to Newton's third law of motion, action and reaction have equal magnitude but acts in opposite direction.

Thus, the brick of mass 10 kg has its weight (due to gravitational pull of the earth), which acts downwards through its center of mass. This makes the scale to produce an opposing force of equal magnitude, which acts upwards. These two forces acting in opposite directions balancing each other.

The two forces acting on the brick are: its weight and the reaction from the scale.

Answer:

Clouds are formed when moist air rises upward . As the air rises , it becomes colder. Eventually the air can't hold all of the water vapour in it, and some of water vapour condenses to form tiny water droplets... Clouds form at wide range of altitudes , from near the ground to very high in the atmosphere.

Answer:

I. Final velocity, V = 10m/s.

II. Distance, S = 10m.

Explanation:

Given the following data:

Acceleration = 5m/s²

Time = 2 seconds

Since the vehicle starts from rest, initial velocity = 0m/s

To find the final velocity, we would use the first equation of motion.

V = U + at

Substituting into the equation, we have

V = 0 + 5*2

V = 0 + 10

V = 10m/s.

Now, to find the distance covered, we would use the second equation of motion.

S = ut + ½at²

S = 0*2 + ½*5*2²

S = ½*5*4

S = 20/2

S = 10m

Answer:

99 joules.

Explanation:

Let m denotes mass of the object and v denotes velocity.

If mass has units of kilograms and the velocity has units of meters per second then the kinetic energy has units of joules.

Kinetic energy is an energy possessed by a body in motion.

Mass (m) = 99 kg

Velocity (v) = 2 m/s

To find kinetic energy, use the following formula:

Kinetic energy = [tex]\frac{1}{2}mv^2=\frac{1}{2}(99)(2)=99[/tex] joules

D. When a chemical reaction releases energy, it is an example of an endothermic reaction.

Explanation:

"Endo" means within. Therefore, an endothermic reaction releasing energy makes no sense.

p.s.

I owe you for your help.

Thank you so much!

The statement that is not true about the chemical reaction is when a chemical reaction releases energy, it is an example of an endothermic reaction, therefore the correct answer is option D.

A chemical reaction is a process in which one or more substances, also known as reactants are converted to one or more different substances, known as products.

A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

Substances with novel characteristics are created through chemical reactions.

Products of chemical reactions differ from the reactants in terms of their features.

Chemical bonds may break or produce new ones during interactions.

The excess energy is released during an exothermic reaction, making the potential energy of the reactant higher than the potential energy of the product. The right response is D.

Explanation:

Impulse = change in momentum = force x change in time

50 x 0.02 = 1

If a baseball is hit by a bat with a force of 50N during a time interval of 0.02s. Then the impulse on the baseball is 1 N s.

An impulse is a quantity that measures the change in momentum of an object. It is defined as the product of force and time, and it is measured in units of Newton seconds (N s) or kilogram meters per second (kg m/s). The impulse experienced by an object is equal to the change in momentum that occurs when a force is applied to it for a specific period of time.

Impulse is practically applied in various areas of physics and engineering. Here are a few examples:

Sports: Impulse is a crucial factor in many sports, especially those that involve hitting or throwing objects. In sports like baseball, cricket, and golf, the force and time of impact determine the ball's momentum and trajectory.

Transportation: The impulse experienced by vehicles during a collision is used to determine the forces that act on the occupants. This information is used to design safety features such as airbags and crumple zones.

Engineering: In mechanical engineering, impulse is used to design machines that can produce large forces over short periods. For example, hydraulic presses use a large force over a short period to shape metal or other materials.

Physics: Impulse is a fundamental concept in physics, particularly in the study of collisions and the conservation of momentum. The impulse-momentum theorem is a fundamental law of mechanics that relates the change in momentum of an object to the impulse applied to it.

Here in the Question,

The impulse on the baseball can be calculated using the formula:

Impulse = Force x Time

Given that the force is 50 N and the time interval is 0.02 s, the impulse can be calculated as follows:

Impulse = 50 N x 0.02 s

Impulse = 1 N s

Therefore, the impulse on the baseball is 1 N s.
