Motion is a change in position measured by distance and time.
Answer:
Explanation:
Resistivity and resistance are proportional and depends of the length and the cross-sectional area of the wire:
furthermore, the density is the mass divided by the volume, and the volume can be written as the area multiplyed by the length:
Now you have tw equations and two variables, so you can solve for each of them.
first, solve for A in both equations and replace them:
now replace this into any of the previous equiations:
If you assume the wire has circular cross-sectional area, then the area is:
solving for d:
replacing A and simplifying:
Answer:
s=1721.344m ,v=104.96m/s.
Explanation:
using thr equation of motion;
u=0, plane starts from rest,
s=1721.344m
v=u+at
v=0 +3.2*32.8
v=104.96m/s
This is honestly not something I’ve learned. The answer is something I don’t know.
Answer:
The change in volume decreases the area over which collisions of
the container and gas particles occur, so the pressure increases.
Explanation:
P = F/A = F ÷ V/h = Fh/V
