Which characteristic describes the stars indicated by the arrow in the image?
cool
hot
large
small
Answer:
The answer is cool.
Explanation:
If you look at the diagram then you can see that the star being pointed to is orange-ish. Red and orange stars are the more cooler ones.
Cool is the characteristic that describes the stars indicated by the arrow in the image. Therefore, the correct option is option A.
What is star?A star is an extremely bright ball of primarily hydrogen and helium-based gas that is kept together through its own gravity. The star is supported against gravity by nuclear fusion events at its core, which also yield photons, heat, and trace quantities of heavier elements.
The star is created when hydrogen nuclei start to fuse into helium nuclei at a temperature of roughly 10 million K (18 million °F) in the gas. The expanding star's core emits energy through nuclear fusion, which eventually slows the gas cloud's collapse. Cool is the characteristic that describes the stars indicated by the arrow in the image.
Therefore, the correct option is option A.

What is the density of a billiard ball that has a volume of 100 cm3 and a mass of 250 g?
Answer:
The answer is 2.50 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 250 g
volume = 100 cm³
So we have
[tex]density = \frac{250}{100} = \frac{5}{2} \\ [/tex]
We have the final answer as
2.50 g/cm³Hope this helps you

value of mass of a body is fixed everywhere. true or false
Answer:
Mass of a body is fixed everywhere. True
Explanation:
What is mass ?Mass is the amount of matter of a body. it is a fundamental quantity. It is a dimensionless quantity.is dimensional symbol is [M].Since amount of a matter is not dependent of place or position therefore it remains same at everywhere.
Hence value of mass of a body is fixed everywhere.

How much work is done when a body of mass m is raised to a height h above the ground?
Answer:
So if an object of mass m is raised through a height h, the work done on the object is equal to mgh, and so this amount of energy is transferred to the object. (Notice that this equation is identical to the one describing an object falling under gravity, Equation

a)the downward force of gravity on the box
b)the upward force of the table on the box
c)the reaction force on the box
d)the push force on the box
We have that from the options, the force require to move the table will be the Reaction force.i.e the force that will get a reaction out of the table i.e is Motion
The reaction force on the box
Correct Option is C
From the question we are told
Lien is pushing a box across a table. She used a force of 100 N to get the box moving
Generally The Force Requird to Move a table is greater than the contiunes force applied to it to en sure it contines in Motion.
Having said that Newtons Third law states for every action there most be an equal and opposite reaction
Therefore
From The options the force require to move the table will be the Reaction for.that is the force that will get a reaction out of the table i.e is Motion

Computer-enhanced x-rays are called __________ scans.
A. TMS
B. PET
C. CT
D. MRI
Answer:
I think the answer is C
Explanation:
EDGE 2020
Computer-enhanced x-rays is called as Computed Tomography (CT) scans. Hence option C is Correct.
What is Computed Tomography (CT) scans ?Computed tomography scan is a medical imaging technique used to get images of our body which is under study. Radiographers or radiology technologists are skilled to handle this machine. It is also know as computed axial tomography scan (CAT scan). it is used to get internal images of the body. It uses rotating X-ray tube and a detector.
CT scans are more detailed than standard X-rays. In standard X-rays, a beam of X-ray is triggered at the body, the beam passes through the body and it gets imposed on the photographic plate which is behind the body. Variation in intensity on the photographic film shows the internal structure of the body. it can not give information about internal organs and other structures.
CT scan combines X-ray images taken at different angles around your body and uses computer for processing to create images (slices) of the bones, and blood vessels. CT scan images gives more-detailed information than X-ray.
Hence option C is correct.

A car stops with an acceleration of -20 m/s/s in 8 seconds. How far did it go while stopping?
Answer:
640 m.
Explanation:
The following data were obtained from the question:
Acceleration (a) = –20 m/s/s
Time (t) = 8 s
Final velocity (v) = 0 m/s
Distance (s) =.?
Next, we shall determine the initial velocity (u) of the car. This can be obtained as follow:
Acceleration (a) = –20 m/s/s
Time (t) = 8 s
Final velocity (v) = 0 m/s
Initial velocity (u)
a = (v – u) / t
–20 = (0 – u) / 8
–20 = – u / 8
Cross multiply
–20 × 8 = – u
– 160 = – u
Divide both side by – 1
u = – 160 / – 1
u = 160 m/s
Finally, we shall determine the distance travelled by the car before stopping as follow:
Time (t) = 8 s
Final velocity (v) = 0 m/s
Initial velocity (u) = 160 m/s
Distance (s) =.?
s = (v + u)t /2
s = (0 + 160) × 8 /2
s = (160 × 8) /2
s = 1280 / 2
s = 640 m
Therefore, the car travelled 640 m before stopping.

Answer:
ca taode na kadato itoi runa ko
Answer:
Explanation:
Sound needs a material medium for their propagation like solid, liquid or gas to travel because the molecules of solid, liquid and gases carry sound waves from one point to another. Sound cannot progress through the vacuum because the vacuum has no molecules which can vibrate and carry the sound waves.
Frequency= no. of oscillations/time=40/60sec

The Indianapolis Motor Speedway has four banked curves, each of which forms a quarter of a circle. Suppose a race car speeds along one of these curves with a constant tangential speed of 75.0 m/s. Neglecting the effects due to the banking of the curve, the centripetal acceleration on the car is 22.0 m/s2. What is the radius of the curve?
Answer:
r = 255.68 m
Explanation:
When a body moves in a circular path, an acceleration, due to constant change in its direction, is developed, known as centripetal acceleration. The centripetal acceleration acts towards the center of the circular path. The formula to calculate the centripetal acceleration is given as follows:
ac = v²/r
where,
ac = centripetal acceleration = 22 m/s²
v = tangential speed = 75 m/s
r = radius of curve = ?
Therefore,
22 m/s² = (75 m/s)²/r
r = (75 m/s)²/(22 m/s²)
r = 255.68 m
