Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ice. Sun is a nearly perfect ball of hot plasma, heated to incandescence in its center by nuclear fusion reactions. Comets can be compared to the sun on the basis of size, composition, and position in the solar system.

<h3>What is the sun?</h3>

The Sun is the central star of our Solar System. It's a nearly perfect ball of hot plasma, heated to incandescence in its center by nuclear fusion reactions.

Sun emits energy mostly as visible light, ultraviolet light, and infrared radiation. It is the most vital source of energy for life on Earth.

<h3>What are comets?</h3>

A comet is a tiny entity circling the Sun that contains a significant amount of volatile ices, which includes entrained dust particles.

The comet forms two tails, one of ionized molecules and radicals and the other of dust, as dust and gas in the coma flow freely into space.

Comets are frozen remnants of the solar system's origin, made of dust, rock, and ice.

They range in size from a few miles to tens of miles across, but as they get closer to the Sun, they heat up and spew gases and dust into a flaming head the size of a jet.

Hence comets can be compared to the sun on the basis of size, composition, and position in the solar system.

What do repeated trails in an experiment allow scientists to do?
fredd [130]

Answer:

Explanation:

When we do multiple trials of the same experiment, we can make sure that our results are consistent and not altered by random events. Multiple trials can be done at one time. If we were testing a new fertilizer, we could test it on lots of individual plants at the same time.

The heat capacity of nickel is 0.444 J/(g · °C). Calculate the amount of heat needed to raise the temperature of 18 g of nickel
azamat

The final speed of the nickel at the given quantity of heat is determined as 202.1  m/s.

<h3>Final speed of the nickel</h3>

Apply the principle of conservation of energy.

Q = mcΔθ

Q = (18)(0.444)(66 - 20)

Q = 367.63 J

Q = K.E = ¹/₂mv²

2K.E = mv²

v = √(2K.E/m)

where;

  • v is the final speed

v = √(2 x 367.63)/(0.018))

v = 202.1 m/s

PLEASE HELP THIS IS DUE LIKE HELP ME PLEASE
marysya [2.9K]

Answer:

At the end points of motion (either side) the velocity must be zero because the velocity is changing from - to + (it can't turn around around without passing thru zero,

The velocity will then increase to the midpoint of the motion.

m g h = 1/2 m v^2    where h is the vertical distance thru which the pendulum travels
