Answer:
Inertia
Explanation:
We have to find that on which quantity the momentum of an object does not depend.
We know that
Momentum of object=mv
Where m=Mass of object
v=Velocity of object
Momentum of object depends upon mass and velocity.
When velocity of object increases then momentum is also increases.
When the mass of object is increases then the momentum of object is also increases.
If mass decreases then the momentum of object decreases.
If velocity decreases then the momentum of object decreases.
Acceleration depends on velocity because
Acceleration=
Therefore, momentum is also depend upon the velocity.
Inertia is defined as the property of object that resist change in its motion.
Therefore, momentum does not depend on Inertia of object.
Answer:
669042 N upward
Explanation:
= Work done by gravity on pile driver
= Work done by beam
u = Initial velocity
v = Final velocity
m = Mass of pile driver = 2200 kg
g = Acceleration due to gravity = 9.81 m/s²
h = Height the pile driver falls = 4.2 m
d = Bend in beam = 14 cm
Total work done = Change in Kinetic energy
The force the beam exerts on the pile driver while the pile driver is brought to rest is 669042 N upward
Answer:
589.3 nm
Explanation:
The wavelength of a sodium light is 5893 A.
We need to find the wavelength in nm.
Also,
So, the wavelength of sodium light is 589.3 nm.
