A capacitor of capacity 10 microfarad is charged through a resistance of 100 kilo-ohms by a DC source of 2 volts. The potential difference across the capacitor after 2 sec will be:

a. 1
b. 2
c. 1.73
d. 1.52

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

this would be about 43%

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)

neg x, pos y

friction

explanation:

they us to move forward and backwards
