Describe the motionof an object that gas acceleration of 0 m/s

Physics
1 answer:
Maru [420]3 years ago
3 0

If an object has acceleration of zero meters per second², then the object is traveling at a constant speed.

Note:  The constant speed doesn't have to be zero, so the object is not necessarily at rest.  It can be moving at any speed, as long as the speed doesn't change.  (If the speed changed, then the acceleration wouldn't be zero.)

Matter that emits no light at any wavelength is called
ruslelena [56]
<span>A negative space is the space around and between the real object. It is the space that forms around the subject after it has altered to give an artistic feel. A dark energy is hypothesized to infuse all of space accelerating the expansion of the universe. It is also an unknown form of energy. A black hole exhibits a strong gravitational pull that no astronomical object can escape from it. A dark matter is a black space in the universe that constitutes most of the unknown. They so not emit light at any wavelength. The answer is letter D.</span>

What organs are involved in caring out these functions?
11Alexandr11 [23.1K]

The human brain is the body's control center, receiving and sending signals to other organs through the nervous system and through secreted hormones. It is responsible for our thoughts, feelings, memory storage and general perception of the world.

The human heart is a responsible for pumping blood throughout our body.

The job of the kidneys is to remove waste and extra fluid from the blood. The kidneys take urea out of the blood and combine it with water and other substances to make urine.

The liver has many functions, including detoxifying of harmful chemicals, breakdown of drugs, filtering of blood, secretion of bile and production of blood-clotting proteins.

The lungs are responsible for removing oxygen from the air we breathe and transferring it to our blood where it can be sent to our cells. The lungs also remove carbon dioxide, which we exhale.

Skin is important in creating a physical barrier to protect the body from pathogens.

we measure a voltage difference of 5.0 V between two points on the conducting paper between two parallel conducting electrodes.
Alex17521 [72]

Answer:

E=1824.81 V/m

Explanation:

Given that

Voltage difference = 5 V

Distance ,D= 3 mm

 θ = 24°

As we know that electric filed given as

E=\dfrac{V}{d}

Given that D is 24° with respect to the perpendicular to the electrodes.So we have to take cos component of D.

d= D cosθ

d= 3 cos24°

d = 2.74 mm

So

E=\dfrac{V}{d}

E=\dfrac{5}{2.74\times 10^{-3}}

E=1824.81 V/m

Color depends on what characteristic of light?
Andrej [43]

Answer:

On the wavelength

Explanation:

Visible light is just a small portion of the electromagnetic spectrum, which classifies all the electromagnetic waves from shortest wavelength (gamma rays) to longest wavelength (radio waves).

Visible light refers to the part of the spectrum which has wavelength between 380 nm and 750 nm. These are the only electromagnetic wave that our eyes can see, and depending on their wavelength, they appear as a different color. In particular, each color corresponds to a different range of wavelengths:

Violet: 380-450 nm

Blue: 450-495 nm

Green: 495-570 nm

Yellow: 570-590 nm

Orange: 590-620 nm

Red: 620-750 nm

the velocity of a car traveling in the positive direction decreases from 32 m/s to 24 m/s in 4 seconds. what is the average acce
anastassius [24]

Answer:

a=-2m/sec^2

Negative sign shows that velocity of the car is decreases at a constant rate

Explanation:

We have given velocity of the car is decreases from 32 m /sec to 24 m/sec in 4 second

So initial velocity of the car u = 32 m /sec

And finally car reaches to a velocity of 24 m/sec

Time taken to change in velocity = 4 sec

So final velocity v = 24 m/sec

From first equation of motion v = u+at

So 24=32+a\times 4

a=-2m/sec^2

Negative sign shows that velocity of the car is decreases at a constant rate
