An inclined plane makes work easier by breaking an upward or downward movement into smaller increments.
A screw is like an inclined plane wrapped around a cylinder. It turns a small rotational force into a larger forward driving force
Explanation:
alike
no contact with the object itself
they can attract objects
they're between 2 objects
difference
source of foundations
type of forces
gravity is only for huge objects
Answer:
7.8% of the original volume.
Explanation:
From the given information:
Temperature 
= 22° C = 273 + 22 = 295° C
Pressure 
= 240 kPa
Temperature 
= 45° C
At initial temperature and pressure:
Using the ideal gas equation:
making V_1 (initial volume) the subject:
Provided the pressure maintained its rate at 240 kPa, when the temperature reached 45° C, then:
the final volume 
can be computed as:
Now, the change in the volume ΔV = V₂ - V₁
∴
The required fraction of the volume of air to keep up the pressure at (240) kPa can be computed as:
= 7.8% of the original volume.
I believe the force of friction would also remain constant because the speed is staying the same.
The idea that <span>Max Planck propose to help explain why a blackbody radiator did not give off light of increasingly high frequency as its temperature increased is that </span>C. Matter can absorb light only in certain specific amounts.
