It will sink because mass does not affect the physical properties of the object.
Crystalline crystals have sharp, well-defined melting points. Amorphous Solids don't have melting points.
4.2m/s. Momentum=mass x velocity so 275/65=velocity=4.23
Answer:
1) 327
2) 3
3) 109
------------
now I'm not 100% sure #4-6 are correct, but if 4 is right then 5 and 6 are, too.
4) 1074
5) 1074 + 109t
6) 2382
Explanation:
Answer:

Explanation:
From work energy theorem
Work done by all forces = Change in kinetic energy
Lets take
m= mass of object
h=height from the ground surface
initial velocity of object = 0 m/s
The final velocity of object is v
Work done by gravitational force = m g . h
The final kinetic energy = 1/2 m v²
So
Work done by all forces = Change in kinetic energy
m g h = 1/2 m v² - 0
v² = 2 g h
