Answer:
The relationship between temperature and kinetic energy is directly proportional.
Explanation:
The temperature is directly proportional to the kinetic energy of the gas molecules. We know that kinetic energy is the energy due to the motion and when gas molecules absorbs heat, they move with more speed and the kinetic energy of particles increases as a result.
According to the kinetic theory of gases
K = 3/2RT/Na
Where K is the average kinetic energy of gas molecules, T is the temperature of the gas, Na is Avogadro's number and R is the universal gas constant.
Answer:
Explanation
The unit of force, Newton is a derived unit because it depends on three fundamental units. i.e kilogram , meter and second.
Hope I helped!
Best regards! :D
it is an example of kinetic energy
so the answer is b kinetic energy
Answer:
Poynting vector, 
Explanation:
It is given that, The electric and magnetic fields of an electromagnetic wave are given by :
Electric field, 
Magnetic field, 
We need to find the Poynting vector for this wave. the Poynting vector is given by :
So, the Poynting vector for this wave is 
. Hence, this is the required solution.
Use Net Force Equation.
Fnet = F1 + F2 + F3 + F4
In which the following main forces in play are:
F1 = Gravitational Force
F2 = Normal Force
F3 = Thrust Force
F4 = Air resistance
Since this is assumed to happen on a flat surface, the gravitational and normal forces cancel out. So we are left with:
Fnet = F(thrust) + F(air resistance)
Now we can use this equation to solve for the net force.
Fnet = 10N [right] + 7N [left]
Fnet = 10N [right] - 7N [right]
Fnet = 3N [right].
Therefore, the total net force acting on this car would be 3N [right]
