Answer:
Momentum of block B after collision =
Explanation:
Given
Before collision:
Momentum of block A = 
= 
Momentum of block B = 
= 
After collision:
Momentum of block A = 
= 
Applying law of conservation of momentum to find momentum of block B after collision 
.
Plugging in the given values and simplifying.
Adding 200 to both sides.
∴ 
Momentum of block B after collision =
The object is moving, so at different times, it has different displacement. I'm guessing that you probably want to know the displacement at the end of the time on the graph ... 5 seconds.
Displacement is the distance and the direction FROM (the position at the beginning) TO (the position at the end).
At the beginning ... time=0 ... the position is 1 meter.
At the end ... time=5 ... the position is zero.
The distance FROM the beginning TO the end is (zero - 1m) . That's <em>-1m </em>.
Answer: tensional force
Explanation:
Tension force on a material occurs when two equal forces act on a material in an opposite direction away from the ends of the material.
Pre-tensing a wire material increases its load bearing capacity and reduces its flexure.
#1).
transfers energy ... both kinds of waves do that
travels in a vacuum ... mechanical waves can't do that
has frequency ... both kinds of waves have
requires a medium ... electromagnetic waves don't need it
2).
infrared, visible, ultraviolet
listed from longest to shortest wavelength
Answer:
The x-component of the electric field at point P -- 31,638.41
Explanation:
Given data:
charge density 
Another charge density 
Electric field due to infinite sheet of charge is given as E
= 31,638.41
