Answer:

Answer:

1. Object

2. Sink

Explanation:

Step-by-step explanation:

1.5 < 1, the object is denser than the fluid

When an object is denser than a fluid it is submerged in, the object will sink.

Answer:

Yellow Light

Explanation:

Low-pressure sodium  lamps gives of a yellow/orange light/glow. Which can also be said as monochromatic yellow light. Because they only produce a single wavelength of yellow light, which results in a less intense light output.

Hopefully this is right! :D good luck

Answer:

it increases the net force pointing down the hill, so she speeds up

Explanation:

Science 6.4.2

Answer:

cold

Explanation:

cold air is more dense than warm air, therefore it has a higher pressure

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.

Answer:

the answer is b. because liquid always bubble when boiling

     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

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.

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.

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.

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.

physical activity can lead to improve the muscle strength workout on maintenance oxygen and vitamins for  tissues and allows the cardiovascular device to work more efficiently, when the heart and lung fitness enhance, energy will be enhanced.

The specificity, progression, overload, variation, and reversibility practicing often and always is so vital if you need to improve your performance.

The training help in development in fitness application are overload, progression, and specificity,  increase the repetitions, a quantity of weight, or length of time in an exercise you are familiar with, you are making use of overload.
