Listed following are various physical situations that describe how light interacts with matter. Match these to the appropriate category.1) TRANSMISSION?-visible light meets clear glass-visible light does not pass through a black wall-red light hits a red sweatshirt-light comes from your computer screen-cell phone signals pass through walls-blue light hits a red sweatshirt-white light hits a white piece of paper-light comes from a light bulb

TRANSMISSION-

visible light meets clear glass

-cell phone signals pass through walls-

Explanation:

Transmission means that light actually passes through an object. Light in this context refers to electromagnetic radiation. All the radiation found in the electromagnetic spectrum are generally called light. This includes radio waves used in telecommunication.

White light is transmitted through glass because it actually passes through the glass.

Passage of cell phone signals through walls is also a typical example of transmission of light.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
