Answer:c
Explanation:
The buoyancy force on toy depends upon the volume of toy under pool water.
According to Archimedes principle buoyant force on a floating body depends upon the weight of displaced liquid by object.
Buoyancy force is given by
where 
=density of fluid
V=volume of object under water
g=acceleration due to gravity
Answer:
<h3>The answer is 3.81 kg</h3>
Explanation:
The mass of the dog can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>3.81 kg</h3>
Hope this helps you
When the force of the opponent's punch is extended, with time, the effect of the blow or the force of the blow is reduced thereby reducing chances for a knockout punch from the opponent to the boxer.
Answer:
the mass of a mercury with volume of 263mL = 3559.3 g or 3.56 kg
Explanation:
given:
263 mL liquid mercury
find:
What is the mass of mercury
we know that the density of mercury = 13.5336 g/mL.
now, calculate the mass = volume x density
plugin values into the formula
mass = 263 mL x 13.5336 g/mL.
mass = 3559.3 g or 3.56 kg
therefore,
the mass of a mercury with volume of 263mL = 3559.3 g or 3.56 kg
Speed (s) = momentum (M) : mass (m)
s = 275kg * m/sec : 65 kg ≈ 4,23 m/sec
