Answer:
Explanation:
In free fall, gravity constantly accelerates an object (increases its velocity)—until it hits terminal velocity. Specifically, gravity increases a falling object's velocity by 9.8 meters per second (m/s) with every passing second. (Whereas velocity is measured in m/s, acceleration is measured in meters per second squared, or m/s2.) How does this constant acceleration affect the distance that an object travels over time? In this experiment you will roll a marble down a ramp to find out.
Answer:
95.3 N
Explanation:
The tension in the cable is found by the equation:
Where 
is the mass density, and 
is velocity.
First we find mass density:
--> 
is mass: 
and 
is length of the cable: 
, so:
And the velocity:
the time is 
and in that time the pulse went down and back along the cable 4 times, if one time down and back is:
2*4.15m=8.3m,
four times this path is:
4*8.3m=33.2m
thus, the velocity is:
And with this data we can now calculate the tension:
The tension is 95.3N
Green: nm 495–570. Yellow: nm 570–590. 590–620 nm for orange. Red: 620-750 nm (400–484 THz frequency)
Solids' molecules are strongly attracted to one another. As a result, the molecules are barely moving and tightly packed. Because of this, shape and volume are fixed.
The forces of attraction and repulsion in liquids are comparable. Compared to the solid state, they move a little bit more. They then assume the shape of the container while still having a fixed capacity.
The attraction forces between the molecules in gases are quite weak. They move quite freely and grow in an effort to fill as much space as they can. Consequently, their volume and shape vary (adopt the shape of the container).
