Nadine knows that she should do some balance training, but she does not know much about it. She already has a full exercise schedule and is worried that she cannot fit in another intense workout session. What is the BEST advice for Nadine?
A.
She can add a few simple exercises to her regular routine.
B.
She really does not need to worry about it if she is stretching.
C.
She won’t get much out of her other workouts if balance isn’t addressed.
D.
She should find at least half an hour to go to the gym and work on balance.
PLEASE NO LINKS
I'm not that sure but I think the answer is D.
Cause without balance most exercises will not be easy to do.
But I suggest u wait for another person to answer.
She already has a full exercise schedule and is worried that she cannot fit in another intense workout session. She should find at least half an hour to go to the gym and work on balance. Thus option D is correct.

-------------------------------is the time measuring device in which periodic motion is produced by mechanical winding.
Answer:
Pendulum ClockExplanation:
Explanation ---> Pendulum Clock is a time measuring device which was possible by the discovery of oscillation in which to and fro motion is present.In a blinding blizzard, a reindeer trudges 310.0 m 55° east of south across the tundra. How far south does the reindeer move? How far east does the reindeer move?
Please show work.
The characteristic of the displacement is a vector allows to find the results for the components of the displacement are;
It moves to the south distance is: y = 177.8 m It moved to the east distance is: x = 253.9 m
The displacement is a vector quantity, therefore it has modulus and direction, see attached for a diagram.
The reference system the West - East axis coincides with the x axis and the South - North axis with the y axis.
Let's use trigonometry to find its components.
cos 55 = [tex]\frac{y}{d}[/tex]
sin 55 = [tex]\frac{x}{d}[/tex]
y = d cos 55
x = d sin 55
let's calculate
y = 310 cos 55
x = 310 sin 55
y = 177.8 m
x = 253.9 m
In conclusion using the characteristics of the displacement is a vector we can find the components of the displacement are;
It moves to the south distance is y = 177.8 m It moved to the east distance is x = 253.9 m

PLEASE HELP ASAP! WILL GIVE BRANLIEST! Pay attention to what happens to the things around you as you go about your day. Describe three examples of Newton’s third law in action. In your examples describe the action and the equal and opposite reaction.
Answer:
jumping, pulling a elastic band, bouncing a ball
Explanation:
when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
When we pull an elastic band, it automatically returns to its original position. The more you pull the more force it generates. This is the same when you pull or compress a spring. The action (applied force) is stored as energy and is released as a reaction with an equal and opposite force
A ball is able to bounce because of the reaction from the ground. If there was no reaction then the ball would not bounce but rather stick to the ground.

Define power and discuss how to determine power worth 4 points
Power is, summarized, how fast something is done using energy. More specifically, power is the amount of energy transferred or converted per unit time.
To determine power, you use the following formula:
[tex]P=\frac{W}{Δt}[/tex]
(formatting is messed up, the denominator is Δt)
P - power
W - work
Δt - elapsed time

Your foot has been stepped on, twice! Both times, a 100 kg person put all their weight on the heel of their shoe upon your foot. The first person was wearing flats, and their heel had an area of 60 cm2. The second person was wearing high heels, and their heel had an area of 9 cm2. What can you say about the two pressures on your foot
The pressure exerted by the shoe of the second person is 6.6 times the pressure exerted by the shoe of the first person.
Se know that pressure is defined as the ratio of force to area. A person that has a mass of 100 Kg has a weight of 100Kg × 9.8 m/s^2 = 980 N. This is the force exerted on your feet.
Now, the area of the first person's shoe = 60 cm2 or 0.006m^2 hence the pressure exerted by the first person is;
P = F/A = 980 N/0.006m^2 = 1.63 × 10^5 Nm-2
The area of the second person's shoe is 9 cm2 or 0.0009m^2 hence the pressure exerted is;
P = 980 N/ 0.0009m^2
P = 1.08 × 10^6 Nm-2
Hence, the pressure exerted by the shoe of the second person is 6.6 times the pressure exerted by the shoe of the first person.

Why does plasma challenge what we know about matter? How does it confirm what we already know?
Being made of charged particles, plasmas can do things gases cannot, like conduct electricity. And since moving charges make magnetic fields, plasmas also can have them. In an ordinary gas, all the particles will behave roughly the same way. Auroras, lightning, and welding arcs are also plasmas; plasmas exist in neon and fluorescent tubes, in the crystal structure of metallic solids, and in many other phenomena and objects. The Earth itself is immersed in a tenuous plasma called the solar wind and is surrounded by a dense plasma called the ionosphere.
Plasma is a type of matter in which many electrons freely roam around the nuclei of atoms.
What is plasma?Although plasma is commonly thought of as a subset of gases, the two states behave very differently. Plasmas, like gases, have no definite shape or volume and are denser than solids or liquids.
Plasma is a sort of matter in which numerous electrons freely roam around the nuclei of atoms.
Plasma has been described as the fourth state of matter, alongside solid, liquid, and gas.
Normally, electrons in a solid, liquid, or gaseous sample of matter remain bound to the same nucleus.
Thus, plasma is considered a distinct phase because it does not conform to the standard descriptions and physical laws that are used to describe the standard three states of matter.
