With a diameter that's 11 times larger than Earth's, Jupiter is the largest planet.
Jupiter is the biggest planet in the solar system. No wonder ancient astronomers named it after Jupiter, King of the Roman gods. More than 1,000 planets the size of Earth could fit inside Jupiter. A tunnel through Jupiter would be 11 times longer than a tunnel through Earth. A trip around Jupiter equator would take 6 times longer than a trip around the Earth's equator. 
        
                    
             
        
        
        
The velocity of sound in at 300C is 511.3 m/s.
Explanation:
The equation that gives the speed of sound in ar as a function of the air temperature is the following:

where
T is the temperature of the air, measured in Celsius degrees
In this problem, we want to find the speed of sound in ar for a temperature of

Substituting into the equation, we find:

So, the velocity of sound in at 300C is 511.3 m/s.

Given parameters: 
Mass of the car = 1000kg 
Unknown: 
Height  = ? 
To find the heights for the different amount potential energy given, we need to understand what potential energy is. 
Potential energy is the energy at rest due to the position of a body. 
  It is mathematically expressed as: 
           P.E  = mgh 
m is the mass 
g is the acceleration due to gravity = 9.8m/s²
h is the height of the car
Now the unknown is h, height and we make it the subject of the expression to make for easy calculation. 
                h = 
<u>For 2.0 x 10³ J;</u>
                   h  =  = 0.204m
   = 0.204m 
<u>For 2.0 x 10⁵ J;</u>
                   h  =  = 20.4m
   = 20.4m 
<u>For 1.0kJ  = 1 x 10³J; </u>
                   h  =  = 0.102m
   = 0.102m
