Density is the ratio of a substance's mass to its volume. On the other hand, according to Archimedes' principle, the volume of water displaced is equal to the volume of the object placed on the water. Thus, the density of the metal is equal to 8.39 mL. So, the density would be
Density = 32.5 g/8.39 mL = 3.87 g/mL

Answer:
180 W
Explanation:
The work done by the man against gravity is equal to its gain in gravitational potential energy:

where
(mg) = 720 N is the weight of the man
is the change in height
Substituting,

The power he must deliver is given by

where
W = 3600 J
t = 20 s is the time taken
Substituting,

Answer:
Hey there
Where trying to say that:
Newton's first law gives the concept of force and momentum?
That's false if that's is what you said.
Newton's first law tells us that objects in motion will remain in motion and objects at rest will remain at rest.
Newton's second law gives us the concept of force and momentum.
