Ingrid says that a red ball of clay appears red because the clay reflects red wavelengths. Simon says that the clay appears red because it allows red wavelengths to pass through it. Which statement best explains who is correct?

Ingrid is correct. The clay appears red because it reflects red wavelengths.
Ingrid is correct. The clay appears red because it is a type of matter.
Simon is correct. The clay appears red because it allows red wavelengths to pass through it.
Simon is correct. The clay appears red because it is a solid.

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

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
