Diffrence between UFP&LFP​

In the formula, 'X' is the temperature value to be converted, 'UFP' is the upper fixed point and 'LFP' is the lower fixed point of the temperature scale

Explanation:

LFP means Lower fixed point and UFP means Upper fixed point. Explanation: There are different scales with different lower fixed point and upper fixed point to measure temperature but the distance between these scales is same in any table or scale considered.

c, 1a hope this

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
