The nand operator (not and) has two inputs and one output. the value of the output is 0 if an only if both inputs are 1. this, you can see, is the not of an and operator. now, recall that an and gate and or gate can each be constructed from two transistors while a not gate can be constructed from one transistor and a resistor. a nand gate can be constructed from two transistors and one resistor. draw the configuration of two transistors and resistor that implement a nand gate.

insects!

explanation:

the answer is to check all of them! they all apply well at least i think so!

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.

attach the statements so i can answer : )
