Answer: Eat only when you're truly hungry instead of when you are tired, anxious, or feeling an emotion besides hunger.
Plan meals ahead of time to ensure that you eat a healthy well-balanced meal.
Keep more fruits, low-fat dairy products (low-fat milk and low-fat yogurt), vegetables, and whole-grain foods at home and at work.

Answer:
I know that some foods have a lot of sugar. I read online that I don’t need any more than 25 grams of added sugar a day. One kind of pop that I like to drink has 40 grams of sugar per can. I can start by drinking less pop. Next, I learned that some food makers are now putting nutrition keys on the front of their boxes. I love all kinds of breakfast cereal, so I can use the nutrition key to compare brands. Cereal high in fiber is good, but cereal high in sugar isn’t. I’ll be more careful, too, when ordering fast food. Sometimes fast-food places want to change the size of my order from medium to large for a higher price. From now on, I won’t pick the bigger meal. Picking the medium-sized meal should be better for me and can even save me money.

In a sonometer by what change in linear density of wire its velocity becomes double? Keeping tension of wire constant
Answer:
Explanation:
In a sonometer , expression for speed of wave produced can be given as follows .
v = [tex]\sqrt{\frac{T}{m} }[/tex]
v is velocity , T is tension in wire , m is density per unit length .
Here v is inversely proportional to square root of m . So if m becomes m / 4
velocity changes as follows .
velocity = [tex]\sqrt{\frac{T}{\frac{m}{4} } }[/tex]
= [tex]\sqrt{\frac{4T}{m} }[/tex]
= 2v
velocity becomes two times . Hence to make velocity two times , mass per unit length has to be changed to one fourth value , keeping tension constant .
Give me the example of junction law and loop law?
Answer:
According to the Junction rule, in a circuit, the total of the currents in a junction is equal to the sum of currents outside the junction. Kirchhoff’s Voltage Law goes by several names as Kirchhoff’s Second Law and Kirchhoff’s Loop Rule. According to the loop rule, the sum of the voltages around the closed loop is equal to null.

In any collision (crash) the_
is ALWAYS constant
Answer:
In any collision (crash) the momentum
is ALWAYS constant
In any collision (crash) the momentum is always constant, whether it is an elastic collision or an inelastic collision the momentum before and after the collision is conserved
What is elastic collision?It is the type of collision in which the total momentum, as well as the kinetic energy of the system, is conserved.
The momentum is always preserved before and after any collision (crash), regardless of whether it is an elastic collision or an inelastic collision.
In the inelastic collision, the momentum is conserved but the kinetic energy of the quantity is not conserved.
The momentum of a quantity is preserved regardless of the type of collision, whether it be an elastic collision or an inelastic collision; the momentum of the quantity will always be conserved.
Hence, The momentum is always preserved before and after any collision (crash), regardless of whether it is an elastic collision or an inelastic collision.

Which arrow correctly indicates the direction of friction acting on the box?
Answer: [tex]F_4[/tex]
Explanation:
The friction opposes motion. We can assume the motion to be downwards because the only force is the weight of the box mgsin(theta) aka F3.
Arrow 4 correctly indicates the direction of friction acting on the box.
What is the friction force?It is a type of opposition force acting on the surface of the body that tries to oppose the motion of the body. its unit is Newton (N).
Mathematically it is defined as the product of the coefficient of friction and normal reaction.
On resolving the given force and accelertaion in the different components and balancing the equation gets.
Friction is a force that resists motion. Because the only force acting on the box is its own weight, we may conclude it is moving downhill. As the force approach the downhill the friction force is acting opposite to it.
Hence, arrow 4 correctly indicates the direction of friction acting on the box.

Skater begins to spend with arms held out at shoulder height. The skater wants to match the speed of the spin to the beat of the music. How does the skater use knowledge of the conservation of momentum to do this?
Answer:
the moment of inertia with the arms extended is Io and when the arms are lowered the moment
I₀/I > 1 ⇒ w > w₀
Explanation:
The angular momentum is conserved if the external torques in the system are zero, this is achieved because the friction with the ice is very small,
L₀ = L_f
I₀ w₀ = I w
w =[tex]\frac{I_o}{I}[/tex] w₀
where we see that the angular velocity changes according to the relation of the angular moments, if we approximate the body as a cylinder with two point charges, weight of the arms
I₀ = I_cylinder + 2 m r²
where r is the distance from the center of mass of the arms to the axis of rotation, the moment of inertia of the cylinder does not change, therefore changing the distance of the arms changes the moment of inertia.
If we say that the moment of inertia with the arms extended is Io and when the arms are lowered the moment will be
I <I₀
I₀/I > 1 ⇒ w > w₀
therefore the angular velocity (rotations) must increase
in this way the skater can adjust his spin speed to the musician.

Work needed = 23,520 J
Further explanationGiven
height = 12 m
mass = 200 kg
Required
work needed by the crane
Solution
Work is the transfer of energy caused by the force acting on a moving object
Work is the product of force with the displacement of objects.
Can be formulated
W = F x d
W = Work, J, Nm
F = Force, N
d = distance, m
F = m x g
Input the value :
W = mgd
W = 200 kg x 9.8 m/s²x12 m
W = 23520 J
What is the main purpose of catabolism? to build up needed molecules in the body to produce energy for use by the body to remove built-up waste in the body.
Answer:
to produce energy for use by the body.
Explanation:
Catabolism can be defined as a metabolic process which typically involves the breaking down of complex molecules (inorganic and organic) into smaller and simpler molecules. This metabolic process (catabolism) is always accompanied with the release of energy in the form of adenosine triphosphate (ADP).
Some examples of the complex molecules broken down through catabolism are proteins, nucleic acid, polysaccharides, and lipids; which are broken into the following smaller molecules, amino acids, nucleotides, monosaccharides, and fatty acids respectively.
Hence, the main purpose of catabolism in living organisms such as humans, animals and plants is to produce energy for use by the body.

6. Abdul moves a magnetic toy train away from a magnet that cannot move. What happens to the
potential energy in the system of magnets during the movement?
a
The potential energy decreases because the train moves in the same direction as the
magnetic force.
b
The potential energy decreases because the train moves against the magnetic force.
С
The potential energy increases because the train moves against the magnetic force.
d
The potential energy does not change because the magnets in the system do not change.
Yeah
Answer: Potential energy increases because the train moves against the magnetic force.
Explanation:
When the magnetic toy train is moved away from a magnet that cannot move, the potential energy in the system of magnets during the movement is affected as there's an increase in the potential energy because the train moves against the magnetic force.
We should note that the potential energy simply means the energy that is stored in the magnetic toy. Since the magnetic toy has been moved away from the magnet, the likelihood of its attraction will reduce thereby there'll be a rise in the potential energy.

A tiny aeroplane accelerates at 35 m/ s2 with a force of 20 N. What is the mass of the aeroplane?
Answer:
0.57 kg
Explanation:
We are given that
Force, F=20 N
Acceleration ,a =[tex]35m/s^2[/tex]
We have to find the mass of Aero-plane.
To find the value of mass we will divide the force by acceleration.
We know that
Force, F=ma
Using the formula
[tex]20=m\times 35[/tex]
[tex]\frac{20}{35}=m[/tex]
[tex]m=0.57 kg[/tex]
Hence, the mass of the aero-plane=0.57 kg
How would you describe impulse in the simplest way possible
Answer:
Explanation:
impulse is a sudden force or desire — this could be an electrical impulse, or an impulse to get some pizza.
If you act on a sudden feeling or thought, you’re following an impulse.
That's like a whim: an impulse isn't something you've given a lot of thought. Another meaning of impulse is an electrical charge or pulse. Electrical impulses are coursing through wires all through your house every day. Both kinds of impulses make things happen. The electrical impulse keeps the refrigerator going, and then you have an impulse to eat all the ice cream in the fridge.

a 28 kg student stand on the surface of the Earth. What is the magnitude of the
gravitational force of the earth on the student?
Answer:
F = 274.68[N]
Explanation:
The gravitational force is equal to the weight of a body, or this case that of a person. Weight can be calculated by means of the product of mass by gravitational acceleration. In this way we have the following equation:
[tex]F=m*g[/tex]
where:
F = force or weight [N]
m = mass = 28 [kg]
g = gravity acceleration = 9.81 [m/s²]
