Answer:
D
Explanation:
Weight and force have same derived units
An increase in the distance between the objects causes a greater change in the gravitational force than the same increase in mass.
This is because the relationship between force and distance for a gravitational force is F ∞ 1/r²
(I couldn't find a proportional sign so I used ∞ instead)
Answer:
0.3376 mm
Explanation:
The computation of the spacing in mm between the slits is shown below:
As we know that
where,
= wavelength
L = distance from the scrren
= spanning distance
As there are 11 bright fingers seen so m would be
= 11 - 1
= 10
Now placing these values to the above formula
So, the spacing is
= 0.3376 mm
We simply applied the above formula.
Answer:
Using the kinetic theory, explain the rise of water in a glass capillary tube. ... Glass and water are composed of different molecules. The force of attraction between the glass molecules and the water molecules is stronger than that among water molecules hence the rise of water in the tube.

Answer:
if your bedroom is empty yes but if not most likely no
Explanation:
Why Cannot we hear an echo in a small room?
They can't hear an echo in small room because in it the sound can't be reflected back. For an echo of a sound to be heard,the minimum distance between the source of sound and the walls of the room should be 17.2 m.Obviously,in a small room echoes cannot be heard.
