How does physical fitness best reflect having a scientific foundation (connected to science)?Explain
Explanation:
Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations and daily activities. Physical fitness is generally achieved through proper nutrition, moderate-vigorous physical exercise, and sufficient rest.
Physical fitness is generally achieved through exercise. Photo shows Rich Froning Jr. – four-time winner of "Fittest Man on Earth" title.
Before the industrial revolution, fitness was defined as the capacity to carry out the day’s activities without undue fatigue. However, with automation and changes in lifestyles physical fitness is now considered a measure of the body's ability to function efficiently and effectively in work and leisure activities, to be healthy, to resist hypokinetic diseases, and to meet emergency situations.
Match the type of boundary with it's characteristic
Answer:
Transform= not destroyed or created
Divergent= crust created
Convergent= crust destroyed
Explanation:
The plates move in the opposite or away from each other at a transforming plate boundary. The two platform borders are not produced or destroyed in this case. As both plates converge on each other and thus destroy the plates for converging plate boundaries. When the plate is divergent, both plates shift away from each other by opening up and solidification for a new crust.
Answer:
Transform= not destroyed or created
Divergent= crust created
Convergent= crust destroyed

Why might a PC monitor be covered with dust?
After gaining electrons from the cloth, can the polythene rod attract small pieces of paper?
Answer:
The attractive forces between the dust particles and Television Screen is due to static electricity. The free dust particles have some residual charge due to force of friction from air or colliding dust particles while the television screen has an opposite charge. They attract and dust settles on it.If a polythene rod is rubbed with cloth, the rod can lift small pieces of paper. This can be explained by stating that the rod becomes charged. A charged object will attract a neutral object until it touches and then it is repelled.Explanation:

Beryllium has a charge of +2, and bromine has a charge of –1. Which is the best name for the ionic bond that forms between them? beryllium bromide beryllium bromine bromine berylliumide bromide berylliumide
Answer:
Beryllium bromide
Explanation:
There exists 2 elements in the question
Beryllium Be with valence of +2, and it's a metal
Bromine Br with a valence of -1, and is a non - metal.
Both of them combine together forming an ionic bond:
Be + Br(2) -> BeBr(2)
In naming the compound, we would say that since the first is a metal, beryllium, and the second being a halogen, bromine. We name it by calling the first name together with the last name and changing the last name of the non metal from -ine to -ide.
So we have, Beryllium Bromide.

An arrow is fired at 5.20 m s−1 at an angle of 22.0° above the horizontal. Find the horizontal component of the initial velocity, expressing your answer in m s−1 to 2d.P.\
Answer:
[tex]4.82ms^{-1}[/tex]
Explanation:
We are given that
Initial velocity, u=5.20m/s
[tex]\theta=22^{\circ}[/tex]
We have to find the horizontal component of the initial velocity.
We know that
Horizontal component of velocity=[tex]ucos\theta[/tex]
Using the formula
Horizontal component of the initial velocity=[tex]5.2cos22^{\circ}[/tex]
Horizontal component of the initial velocity=[tex]5.2\times 0.9272[/tex]
Horizontal component of the initial velocity=[tex]4.82ms^{-1}[/tex]
Hence, the horizontal component of the initial velocity=[tex]4.82ms^{-1}[/tex]

A car is launched by a spring and goes to the top of a loop. Fill in the energy bar chart by drawing a vertical bar(s) in the correct position (both Initial & Final conditions).
Answer:
A) the initial point all energy is elastic potential and the final point all energy is kinetic
B) a bar graph the two bars have the same height and the sum of their height is the initial energy
C) two bars, one for the kinetic energy and the other for the gravitational potential energy.
Explanation:
A) For this exercise we must use the energy conservation relations
starting point. When the spring is compressed
Em₀ = K_e = ½ k x²
end point, at the bottom of the loop
Em_f = K = ½ m v²
energy is conserved
Em₀ = Em_f
½ k x² = ½ m v²
v = [tex]\sqrt{ \frac{k}{m} }[/tex] x
In a bar graph the initial point all energy is elastic potential and the final point all energy is kinetic
B) intermediate point in a quarter of the radius
In this case we use the lower part of the loop as the starting point and the quarter part of the bow as the end point.
Em₀ = K
Em_f = K + U = ½ m v² + m g R
in a bar graph the two bars have the same height and the sum of their height is the initial energy
C) End point highest part of the loop
starting point, bottom of loop
Emo = K = ½ m v₀²
from part A of the exercise we saw that it is equal to the elastic energy of the spring
final point. Highest part of the loop
Emf = K + U
Em_f = ½ m [tex]v_{f}^2[/tex] + mg (2R)
where R is the radius of the loop
Em₀ = Em_f
1/2 m v₀² = 1/2 m v_{f}^2+ mg 2R
v₀² = v_f^2 + 4gR
In a bar graph there are two bars, one for the kinetic energy and the other for the gravitational potential energy. The sum of the heights of these bars is the initial energy, so the energy is transformed but not created or destroyed in the process.

What is Newton's 2nd law dealing with acceleration
Answer:
Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.
