What is cardio?Any form of exercise that raises your heart rate and keeps it there for a long time is considered cardio. As you start to breathe more quickly and deeply, your respiratory system will start to work harder.
The four components of a fitness program are flexibility, cardio, strength, and power.
The physical exercise that increases muscular strength and fitness is referred to as strength.The capacity to produce the most muscle contractions possible during a movement is referred to as power.Cardio refers to the capacity to handle various circumstances of various lengths.Flexibility is the characteristic that is linked to the range of motion offered by a particular joint.Therefore, the correct option is D. His program works for him, so he should not change it.

When two atoms bond chemically it is because of the interaction between
A) the nuclei of each atom.
B) the protons in each atoms.
C) all electrons in the atoms.
D) the valence electrons in each atom.
Pls hurryyyy!!!
Answer:
Explanation:D
When two atoms bond chemically it is because of the interaction between the valence electrons in each atom because only the valence electrons of an atom are responsible for the chemical activity.
Therefore the correct answer is option D.
What is a chemical reaction?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.
Because only an atom's valence electrons are responsible for the chemical activity and because the quantity of valence electrons indicates an atom's valency,
Valency is a highly important requirement for the chemical reactivity of any element, two atoms connect chemically as a result of their contact.
Thus, the correct answer is option D.

an object applies force of 500n on the area if 10m². find the force exerted
Exerted force is called Pressure.
From,
Pressure = Force/Area
P = 500N/10m²
P = 50N/m²
The force exerted is 50N/m²
although the pivot exerts a force on the ruler it does not exert a torque with respect to the pivot point. why not?
Answer:
The situation is not shown, however if one calculates torques about the pivot point, then the pivot point itself exerts no torque because the force applied by the pivot point exerts zero torque because Fp * L = 0 where L = 0 in this case.
If one wants to calculate torques about, say, the end of the ruler then one would need to calculate the torque applied by the pivot point.
a body has a weight of 2.8 Newtons what is the Mass of the body in grams
Answer:
285.7 g
Explanation:
Weight = mass x gravity
mass has units of kilograms
gravity is 9.8 m/s²
newton units are kg m / s²
So:
2.8 kg m/s² = mass x 9.8 m/s²
Divide both sides by 9.8
2.8 kg m/s²
---------------- = mass in kg = 0.2857kg
9.8 m/s²
Convert kilograms to grams by multiplying by 1000
0.2857kg 1000 g
-------------- X --------------- = 285.7g
1 1 kg

a dog is running at 5.5 m/s then comes to a complete stop in 1.5 seconds. What is the dogs acceleration?
The dog's acceleration running at 5.5 m/s then comes to a complete stop in 1.5 seconds is 8.25m/s²
HOW TO CALCULATE ACCELERATION:
The acceleration of a moving object can be calculated by multiplying the velocity of the object by the time taken. That is;Acceleration (m/s²) = speed (m/s) × time (s)According to this question, a dog is running at 5.5 m/s then comes to a complete stop in 1.5 seconds. The acceleration can be calculated as follows:Acceleration = 5.5 × 1.5Acceleration = 8.25m/s²Therefore, the dog's acceleration running at 5.5 m/s then comes to a complete stop in 1.5 seconds is 8.25m/s².Learn more at: https://brainly.com/question/19573976?referrer=searchResults

Explanation:
Well ball on ramp .Which factors are affected?
Centre of massAcceleration due to gravity Mass of ball .Force appliedSo if we put the ball right above the centre of mass it can be best stabled
A ball Of Mass. 0.5 kg initially at rest is kick directly toward offense from appoint 20 m away as shown below the velocity of the ball as it leaves the kickers foot is 16 M/S at angle 45 degrees above the horizontal the top of the fence is 4 m high the ball hits nothing Wallen flight and a resistance is negligible the acceleration due to gravity is 9.8 M/S^2 determine the time it takes for the ball to reach the plane of the fence.
Answer:
a. The horizontal component of the velocity is constant so vxt = d where vx = v0 cosθ = 16m/s t = d/v = 2s
b. The height of the ball during its flight is given by y = v0yt + ½ gt2 where v0y = v0sinθ = 12m/s and g = –9.8m/s2 which gives at t = 2s, y = 4.4m. The fence is 2.5m high so the ball passes above the fence by 4.4m – 2.5m = 1.9m

An airplane flies with a velocity of 750. kilometers
per hour, 30.0° south of east. What is the
magnitude of the eastward component of the
plane's velocity?
A. 866 km/h
B. 650. km/h
D. 375 km/h
C. 433 km/h
The magnitude of velocity in east direction will be 650 N approximately.
What is velocity ?
velocity is given by the change in distance by the object with respect to change in time. It is a vector quantity and having S.I unit as m/s.
Here it is given that magnitude of velocity is 750 N and making an angle of 30 degree with x axis in counterclockwise direction as shown in figure below :
Now resolving and writing magnitude of velocity V in x and y direction respectively :
[tex]\begin{aligned}Vcos\theta&= 750 cos30^{o}=650 \:m/s\\Vsin\theta&= 750sin30^{o}= 375 m/s\end{aligned}[/tex]
It should be noted that [tex]vsin\theta[/tex] is acting in negative y direction.
Therefore, the magnitude of velocity in east direction is 650 m/s

What do you think will happen to current if we increase or decrease the resistance of the connecting wire?
Answer:
If resistance is increased, the current decreases and if the resistance is decreased, the current flowing through the wire increases.
Explanation:
V = IR is ohm's law which implies I = V/R, where I is the current and V is the voltage and R is the resistance. Hence, I is inversely proportional to R.

what is the smallest possible value for the index of refraction?
Answer:
1.0
Explanation:
The smallest possible value for the index of refraction is 1.0.
What is Index of refraction?This talks about how fast light travels through an object by taking note of how much the light is bent, or refracted, as it enters into the material.
The smallest possible value for the index of refraction is 1.0 because the speed of light in any medium is always less than than the speed of light in air or vacuum.
