A certain object is subject to two forces: a 10-N force straight up and a 10-N force straight down. A student stated that since both forces are in the vertical direction, the object cannot be moving horizontally. Why is this an incorrect conclusion? A. The vertical forces are balanced.
B. Vertical net forces can cause horizontal motion
C. horizontal force is not required for horizontal movements.
D. Two vertical forces can combine to form from a horizontal motion.

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.

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

i think the answer would be reserve.

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
