2.4 how?
i discussed it with my friends
they all had 1.2

IDK

 

[amina1300]

What about the first question how'd u guys solve it

 

[Holmes]

IDK

or maybe I am thinking of a wrong question

 

[anastasia grey113]

What about the first question how'd u guys solve it

well the velocity was 2.4
by equating potential and kinetic energy

 

[anastasia grey113]

or maybe I am thinking of a wrong question

yes u r
this was question 1 velocity xDD

What about the first question how'd u guys solve it

line of force is simly where a mas experinces a force toward the direction of the line

 

[Holmes]

What do you guys think the threshold will be this time?

Below 55 for sure

 

[haithsoul]

a

What about the first question how'd u guys solve it

and the rock WILL escape

 

[anastasia grey113]

line of force is simly where a mas experinces a force toward the direction of the line

yh i wrote the direction of the gravitational force applied by the object
its attractive so usually towards the object

Formula for the gain?

and the rock WILL escape

yeapp lol since 2.8>2.4

 

[haithsoul]

Formula for the gain?

gain was 8

 

[anastasia grey113]

Formula for the gain?

Rf/Rin + 1 since it was non inverting

 

[anastasia grey113]

gain was 8

wasnt it 9?

 

[Holmes]

wasnt it 9?

It was 9

 

[anastasia grey113]

It was 9

yh lol
and we had to replace the 6400 resistor with a thermistor right

 

[haithsoul]

wasnt it 9?

god damn

 

[anastasia grey113]

god damn

its ok youll get an ecf

 

[haithsoul]

n

yh lol
and we had to replace the 6400 resistor with a thermistor right

no it said the gain was constant so you put resistor with v in

 

[anastasia grey113]

n

no it said the gain was constant so you put resistor with v in

it said decreasing gain with increasing temperature no?
