Ciner forms when there is a series of violent and gentle eruptions resulting in layering of lava and ash
Answer:
In space we feel weightlessness because the earth's gravity has less effect on us. The Earth's gravitational attraction at those altitudes is only about 11% less than it is at the Earth's surface. If you had a ladder that could reach as high as the shuttle's orbit, your weight would be 11% less at the top.

Explanation:
One way of classifying stars is by their temperature .
or
Science strives to be able to describe how stars and planets form and evolve. This requires theories to describe the processes which include:
Star and planet formation
Star and planet composition
Stellar and solar system evolution
The nuclear processes happening inside stars
The scientific method means that all theories are put to the test. By measuring or calculating the temperature, age and composition of other planets and stars the theories can be tested. If observed values of these parameters are not predicted by theories, then the theories are wrong and need to be revised or replaced.
The percentage of the drink that finds the target and lands in your mouth.
Answer: The correct option is Option b.
Explanation:
Power is defined as the rate of work done by an object.
Mathematically,
.....(1)
And work done is the product of force exerted on the object times the displacement covered by that object.
Mathematically,
![W=F.s](https://tex.z-dn.net/?f=W%3DF.s)
Putting this value in above equation, we get:
![P=\frac{F.s}{t}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7BF.s%7D%7Bt%7D)
where,
P = power = ?W
F = Force exerted = 10N
s = Displacement = 400cm = 4m (Conversion factor: 1m = 100 cm)
t = Time taken = 8s
Putting values in above equation, we get
![P=\frac{10\times 4}{8}\\\\P=5W](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B10%5Ctimes%204%7D%7B8%7D%5C%5C%5C%5CP%3D5W)
Hence, the correct option is Option b.
