Answer:
= 4.38 × 10³⁴kgm²/s
Explanation:
Given that,
mass of moon m = 9.5 × 10²²kg
Orbital radius r = 4.28 × 10⁵km
Orbital period T = 28.9days
T = 28.9 × 24 × 60 × 60
= 2,496,960s
Angular momentum of the moon about the planet
L = mvr
L = mr²w
Answer:
Option D.
Explanation:
The correct answer is Option D.
The shrinkage of the bridge material is because of thermal contraction.
Thermal contraction and thermal expansion are the phenomena of the bridge material which takes place due to the change in temperature of the atmosphere.
When the temperature of the surrounding increases expansion of the bridge material takes place and when temperature decreases the contraction of the material takes place.
This phenomenon sometimes damages the structure because due to continuous expansion and contraction of materials strength of the bridge decreases.
Answer:
The input force is the force that when you push down and the output force is the stable going into the paper.
Explanation:
I really hope this helps ;)
Answer:
False
Explanation:
Diffraction is slight bending of the light as it passes around edge of object.
It is caused as one wave of the light being shifted by the diffracting object. The shift will then cause wave to have the interference with itself. The interference can be constructive or destructive.
The patterns of the interference rely on size of diffracting object and size of wave.
Hence, the given statement is incorrect.
