A charge-coupled device (CCD) is a light-sensitive integrated circuit that captures images by converting photons to electrons.
A touch screen is a computer display screen that is also an input device. The screens are sensitive to pressure; a user interacts with the computer by touching pictures or words on the screen.
The similarity is the sensitivity.
The difference is CCD scans or ‘takes images’, whereas touch-screen is where a user interacts with the software.

Upthrust is the force that is pushing you up. Kinda to stop you from sinking right into the Earth. Upthrust is simply any force that is causing something to be pushed upwards. Kinda like the opposite of gravity, which is pulling you down =]
Hope this helps ❤️
Explanation:
Many would know it as a reaction force. Reaction force is the force by the surface on the object perpendicular to it's motion. So if we apply force on the sliding block perpendicular to it's direction of motion, friction will increase. ... That force is proportional to the velocity with which it is moving.
