Data analysis
part a: claim: the cart will have a change in mechanical energy of 48 / as its au
by 12 m.
ollect evidence about the physical meaning of the area under the line on the graph that can be
used to support the claim above. write an equation (including units) for the area between the force
line and the x-axis between x = 0 m and x = 12 m
evidence: the area under the line of the force vs. displacement graph is equal to
_. this area is also known as the
number units number units number units
physical quantity
done on the object.
reasoning: fill in the blanks of the following statement:
the claim makes sense because the
- done on the cart is also equal to the change in
of the cart.
part b: explain how the graph above could be used to determine the final speed of the cart after 12 m.

50 inches should be the resultant vector

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
