Answer:
D. Nuclear fusion
Explanation:
Nuclear fusion is a nuclear reaction where nuclei of atoms( one of low atomic number and another with a higher atomic number) join together to form a much bigger nucleus and release a lot of energy.In the sun, which is a star of course, where light is released,hydrogen is converted to helium and the process releases massive energy into space in form of heat and light.
To find wave speed, you multiply the wavelength by the frequency. This means it is 8 times 11. This gives you 88. That means the answer is 88mm/s
Answer:
Resistance = 68.23 Ω
Explanation:
Let's start off by remembering the fact that when resistors are connected in series, their resistances is added up to find the total resistance.
The equation for resistance using resistivity is given below:
Resistance = Resistivity * Length / Area
where Length = x
Resistivity = 3x^5
and Area = = 8.04 * 10^(-8) meter squared
Substituting in the value of resistivity, length and area we get:
Resistance =
Resistance =
Since resistance in series is added, we can simply integrate this formula over the length (x = 0 to x = 0.2) to get the total resistance.
Resistance =
Resistance =
Resistance = 68.23 Ω
Answer:
Isothermal process = Temperature is constant
Explanation:
- As the name implies, iso means same and thermal is related to temperature.
- In isothermal process, the temperature of the system remains constant throughout.
- The exchange of heat takes place such that the thermal equilibrium is maintained.
- Hence, the correct option is (c) " temperature is constant".
