1 answer:

3 0

<span>Heat in a substance is still an example of heat or thermal energy. Heat or thermal energy is further defined as the amount of available molecules of kinetic energy transferred in a specific amount of time. Heat is nothing if it is not transferred from one object to another. There are many uses of heat energy. When we are cooking using our stoves, there is heat energy. When we pour hot water onto our cup of coffee, there is heat energy.</span>

Answer:

CLAIM: When you eat the hamburger, your body uses it and breaks it down which is chemical energy than use that food for energy for mechanical energy which makes thermal energy

EVIDENCE: This happens every day to people across the world and also it is scientifically proven

REASONING: The reason why this evidence supports it is because as I said it happens everyday and when you feel energized after and apple after you were lazy that just happened

A 45.2-kg wagon is towed up a hill inclined at 18.5∘ with respect to the horizontal. The tow rope is parallel to the incline and

drek231 [11]

Answer:

The speed is 29.9 m/s

Explanation:

The force created from gravity due to the wagon mass is:

$F=m*g*sin(18.5)\\F=45.2*9.8*sin(18.5)\\F=140.55$

140.55 N pull the wagon down. Two parallel rope with tension of 191N creates 382 N on the wagon. Therefore:

$T_{total}=382-140.55=241.45$

241.45 N force is pulling up the wagon. Then we need to find the acceleration of the wagon under this force:

$F=m*a\\241.45=45.2*a\\a=5.34$

acceleration is 5.34 m/s^2. The distance is multiplication of acceleration and square of the time.

$x=1/2*a*t^2\\83.8=0.5*5.34*t^2\\t=5.6$

After 5.6 second the wagon will ride 83.8 m up to hill. And the speed of wagon at that point is:

$v=a*t\\v=29.9$

We have compared the Terrestrial Planets and the Giant or Jovian Planets, but when we look at the 4 Giant Planets we can see tha

Ksivusya [100]

Answer:

i. Magnetic fields

ii. All 4 planets in appearance have deeper atmospheres and darker cloud.

iii. All the 4 Jovian planets rotates very quickly, with a range of 10 to 17 hours.

Explanation:

The Jovian planets is different from terrestrial planets in so many ways. The Jovian planets includes Jupiter , Saturn, Uranus and Neptune.

The major similarities shared by all of these 4 planets includes

i. Magnetic fields: Each of this Jovian planets have a strong magnetic field and are generated by electric currents in its rapidly sniping interior. The magnetosphere which is the region at which the planet magnetic field dominates is far more stronger in Jupiter than other Jovian planets . Although the magnetic field of Saturn , Neptune and Uranus works in similar way to Jupiter but are less stronger.

ii. All 4 planets in appearance have deeper atmospheres and darker cloud. The uppermost clouds of Jupiter and Saturn has more of ammonia crystals .The upper cloud of Neptune is composed of methane, The cloud of Uranus is deep.

iii. All the 4 Jovian planets rotates very quickly, with a range of 10 to 17 hours. The rotation period of Jupiter is the shortest among the Jovian planets which is around 9 hours 55 minutes. The rotation period of Neptune and Uranus take longer time than the other 2 Jovian planets( a little above 17 hours).
