Answer:
Because it is above the Earth's atmosphere. The atmosphere disturbs the starlight (a bit like looking through water) and blurs the images. So Hubble's images are much sharper than those from other telescopes.
Explanation:
Answer:
Hubble's orbit outside the distortion of Earth's atmosphere allows it to capture extremely high-resolution images with substantially lower background light than ground-based telescopes. It has recorded some of the most detailed visible light images, allowing a deep view into space.

The image on the left shows the charges on a balloon after it’s been rubbed with a wool cloth. The image on the right is a piece of tissue paper. What will happen to the tissue paper as it approaches the balloon and why? A. The tissue paper will stick to the balloon because the tissue paper is negatively charged. B. The tissue paper will stick to the balloon because the tissue paper is positively charged. C. The tissue paper will move away from the balloon because the tissue paper is negatively charged. D. The tissue paper will move away from the balloon because the tissue paper is positively charged.
When the balloon comes in contact with the tissue paper it will stick to the balloon because the tissue paper is positively charged.
What is static electricity?Static electricity is the electrical current generated when a negatively charged material polarize other material temporarily. When a material is rubbed with a conducting surface it will gain electrons and become s negatively charged.
When this negatively charged body comes in contact with a nonpolar material, The non-polar one will be polarized partially and its positive charges will allocate near the negative charges.
When the balloon is rubbed on a wool it gans negative charges and the electrons from the balloon tends to attract the positive pole of the tissue paper and the paper will stick on it. Thus, option B is correct.

What is heat?What are it's units?
Answer:
As a form of energy, heat has the unit joule (J). The standard unit for the rate of heat transferred is the watt (W), defined as one joule per second.
heat is a form of energy therefore the unit of heat is the same as that of energy has the CGS unit of heat is erg and its SI unit is Joule
relationship between Joule and erg is --

You are asked to design an experiment which is similar to Match Graph activity. If you move 3m back from the motion sensor in 2s. What is your speed?
Answer:
The speed is 1.5 m/s.
Explanation:
Given that,
Distance = 3 m
Time = 2 sec
We know that,
The position and time graph shows the speed of motion.
We need to calculate the speed
Using formula of speed
[tex]v=\dfrac{d}{t}[/tex]
Where, d = distance
t = time
Put the value into the formula
[tex]v=\dfrac{3}{2}[/tex]
[tex]v=1.5\ m/s[/tex]
Hence, The speed is 1.5 m/s.

how light is channelled down an optical fibre
Explanation:
Suppose you want to shine a flashlight beam down a long, straight hallway. Just point the beam straight down the hallway -- light travels in straight lines, so it is no problem. What if the hallway has a bend in it? You could place a mirror at the bend to reflect the light beam around the corner. What if the hallway is very winding with multiple bends? You might line the walls with mirrors and angle the beam so that it bounces from side-to-side all along the hallway. This is exactly what happens in an optical fiber.
The light in a fiber-optic cable travels through the core (hallway) by constantly bouncing from the cladding (mirror-lined walls), a principle called total internal reflection. Because the cladding does not absorb any light from the core, the light wave can travel great distances.
However, some of the light signal degrades within the fiber, mostly due to impurities in the glass. The extent that the signal degrades depends on the purity of the glass and the wavelength of the transmitted light (for example, 850 nm = 60 to 75 percent/km; 1,300 nm = 50 to 60 percent/km; 1,550 nm is greater than 50 percent/km). Some premium optical fibers show much less signal degradation -- less than 10 percent/km at 1,550 nm.

What is the length of the x-component of the vector shown below?
A. 72.5
B. 8.1
C. 23.6
D. 34.1
Answer:
Option B. 8.1
Explanation:
From the question given above, the following data were obtained:
Angle θ = 71°
Hypothenus = 25
Adjacent = x
Thus, we can obtain the x component of the vector by using the cosine ratio as illustrated below:
Cos θ = Adjacent /Hypothenus
Cos 71 = x/25
Cross multiply
x = 25 × Cos 71
x = 25 × 0.3256
x = 8.1
Therefore, the x component of the vector is 8.1

Which sports are similar to the sport that you’ve chosen? How are the sports similar? How are they different?
Answer:
sports are not that simular they are just diferrent ok bud
Explanation:
Answer:
if you chose boxing..
Explanation:
Boxing is similar to any one-on-one sport where opponents go head to head. I think it’s like wrestling, karate, and mixed martial arts. The sports are similar in that they require one opponent to overtake another. They are different in how that is accomplished. For example, karate and mixed martial arts are about striking. But wrestling is about putting someone in a hold without hitting them. Boxing and wrestling have been around for a long time. I think karate has too.

Cars powered by hydrogen fuel cells emit which substance?
oxygen
carbon dioxide
hydrogen
water
Answer:
Water
Explanation:
Just took it and got a 100 :)
Cars powered by hydrogen fuel cells will emit hydrogen. The correct option is C.
What is a hydrogen fuel cell?
If hydrogen is produced using a process that does not require carbon, it can be burned with oxygen and emits no carbon when doing so. It can be applied to internal combustion engines or fuel cells.
One endeavor to lower vehicle emissions is the development of cars driven by hydrogen fuel cells. These vehicles use hydrogen gas that has been kept under specific circumstances to produce electricity that powers the motor.
Water vapors are released when hydrogen and oxygen are burned. It doesn't release any dangerous chemicals, including greenhouse gases. It is a substitute that has no emissions that harm the environment. It is a very good choice for the future, especially given the current level of pollution around the globe and the depletion of fossil resources.
