-- There are three pairs of mass with gravitational forces between them.
-- The distances between the masses are the same for each pair.
-- The only other quantity that determines the strength of the gravitational
force is the product of the masses.
-- The product of the masses is greatest for the apple and the watermelon,
so the strength of the gravitational force between them is the greatest.
Answer:
2.933 kg m/s
Explanation:
impulse = change in momentum
impulse = mass ( final velocity - initial velocity )
= 0.0459 ( 63.9 - 0 )
= 0.0459 × 63.9
= 2.93301 kg m/s
or = 2.933 kg m/s up to 4 significant figures
Answer:
We know that the time period of the vibration of the second's pendulum is T=2s. Hence, the length of the second's pendulum is 99.3 cm
Scientists use their data to make charts and graph to communicate the results of an experiment.
