The strength of the gravitational forces between two objects is completely determined by
<em>-- the masses of the objects</em>
<em>-- the distance between the centers of the objects.</em>
Nothing else has any effect on the strength of the gravitational forces between them. Not their motion, or other forces acting on them, or a steel, concrete, and Kryptonite wall between them.
Answer:
Question
Explanation:
The independent variable in Part I, the one that is intentionally manipulated, is the
.
The independent variable in Part II, the one that is intentionally manipulated, is the
.
The independent variable in Part III, the one that is intentionally manipulated, is the
.
The independent variable in Part IV, the one that is intentionally manipulated, is the
.
After rolling off the edge of the cliff and falling ' M ' meters down,
the speed of the boulder is
Square root of ( 19.6 M ) .
If M=111 meters, then the speed is <em>46.64 meters per second</em>.
We have known for roughly 500 years that if there's no air resistance,
the mass of the falling object makes no difference, and all objects fall
with the same acceleration, speed, time to splat, etc.
Answer:
v = 6.315 cm
Explanation:
given,
R₁ = 4 cm = 0.04 m
R₂ = 15 cm = 0.15 m
n =1.5
v = 0.06315 m
v = 6.315 cm
hence, the distance of the image from the back surface is v = 6.315 cm
Due to the bucket not moving, the bucket will solely have potential energy. because potential energy=mgh, the energy of the bucket will equal 50(9.8)(3), which is 1470 joules.
