How does the composition of a comet compare with that of the Sun?.
alekssr [168]

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.

The complete combustion of a small wooden match produces approximately 512 cal of heat. How many kilojoules are produced? Expres
k0ka [10]

We have to covert 512 cal of heat in kilo joules.

As, 1 cal = 0.004184 kJ = 4.184 joules.

Therefore,

512 \ cal = 512 \times 4.184 \ J = 2142.208 \ J \\\\\ =  2.142 \times 10 ^3 J = 2.142 \ kJ

Thus, combustion of a small wooden match produces approximately ( in kilo joules ) is 2.142 kJ .

A force of 100. newtons is used to move an object a distance of 15 meters with a power of 25 watts. Find the time it takes to do
Flauer [41]
<h3>It takes 60 seconds to do the work</h3>

<em><u>Solution:</u></em>

Given that,

Force = 100 newtons

Distance = 15 meters

Power = 25 watts

To find: time it takes to do the work

<em><u>Find the work done:</u></em>

work = force \times displacement\\\\work = 100\ newtons \times 15\ meters\\\\work = 1500\ joule

<em><u>Find the time taken</u></em>

power = \frac{work}{time}\\\\25\ watts = \frac{1500\ joule}{time}\\\\time = \frac{1500\ joule}{25\ watt}\\\\time = 60\ second

Thus it takes 60 seconds to do the work
