That only happens when the temperature is below freezing and the air around the ice is dry.
The answer is the first one. That's because the general theory of relativity is the thing experiencing whatever is experiencing relative to something else. The second answer is just plain wrong. The third answer is just a constant, and doesn't relate to experiencing anything. And the fourth answer is a force between two objects, and it has no second comparison. The first answer is how a subject experiences two different things.
Answer:
Part a)

Direction of force is along the motion of charge
Part b)

direction of electric field is along the direction of motion
Explanation:
Part a)
As we know that the change in electric potential energy is equal to the work done by electric field


now from the equation of work done we know that



Direction of force is along the motion of charge
Part b)
As we know the relation between electrostatic force and electric field given as



direction of electric field is along the direction of motion
Answer:
File transfer protocol secure (FTPS)
Explanation:
File transfer encryption is an essential security measure that prevents outsiders from being able to read or understand the data that is being transferred. This protects the information from potential hackers.
There are three options for encrypting file transfer data: FTPS (File Transfer Protocol Secure), FTP (File Transfer Protocol) and HTTPS (HTTP Secure).
File Transfer Protocol (FTP) and File Transfer Protocol secure (FTPS) are used for transferring files. However FTPS is the only secure, encrypted protocol.
