KE= .5*M*V^2
.5*.5*10^2
=25Joules
the answer should be b) molecules because molecules are what creates a amino acid
Explanation:
36. How long does it take a car to slow down from a speed of 54 km/h to 32 km/h over a distance of 65 m? Answer in seconds. 37.
Answer:
2.15 m
Explanation:
Newton's Law of Universal Gravitation:
is the gravitational force of attraction
is the universal gravitational constant
and
are the two masses of the two objects
is the distance between the centers of the two objects.
List the known values:
Plug these values into the equation:
Notice that the units
,
, and
cancel out. We are left with the unit
for radius r.
Get rid of the units to make the problem easier to read.
Multiply the masses together.
Multiply the gravitational constant and the masses together.
Solve for
by dividing both sides by 3.47 * 10^(-8) and moving
to the left.
Take the square root of both sides.
The students are sitting about 2.15 m apart from each other.
I think unbalanced forces is one of the reasons
