Stars that have masses approximately 0.8 times the mass of the sun take about 18 billion years to turn into red giants. how does this compare to the current age of the universe? would you expect to find a globular cluster with a main-sequence turnoff for stars of 0.8 solar mass or less? why or why not?

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day

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.
