Mach 5. Mach 1 is defined as the speed of sound. The number after “Mach” is the multiplier. So Mach 5 is 5x the speed of sound.
Answer:
Explanation:
For transitions:
Also,
Where,
h is Plank's constant having value
c is the speed of light having value
So,
So,
Given,
1 m = 10⁻⁹ nm
Answer:
Every object located in the universe emits radiation.
Explanation:
This is the fact which represents evidence of The Big Bang Theory.
Accurately
Explanation:
If we took our laboratory spring to the moon, we can accurately measure the mass because mass of any substance is the same every where in the universe.
Mass is the amount of substance in a matter. Since the same substance on earth is made up of same matter on moon, the mass will remain the same.
- The only difference between the measurement would be the weight.
- Weight is the vertical force on an object.
- It is function of mass and acceleration due to gravity.
Weight = mass x acceleration due to gravity.
- Acceleration due to gravity on earth and moon are different.
- The gravity on moon is about one-sixth that on earth.
- The weight using the same mass will be one-sixth
- But the mass will be the same.
