2^2х^2 + 25y^2-128x -100-44= 0
​

Answer 1

Answer:

sorry

Step-by-step explanation:

8. Three resistances x1, X2, and x3 are connected in a circuit in different ways. x is the effective resistance. The properties observed for these different ways of connecting x1, X2 and x3 are given below. Write the way in which they are connected in each case. (I-current, V-potential difference, X-effective resistance)

a. Current I flows through x1, x2 and x3

b. x is larger than x1, x2, and x3

c. x is smaller than x1, X2 and x3

d. The potential difference across X1, X2

and x3 is the same

e. x = x1 + x2 + x3

f. x = 1/(1/x1 + 1/X2 + 1/x3)

Answer 2

a)Since velocity is not changing, acceleration is equal to zero.

(b) Reading the graph, velocity=20ms

−1

(c) s = area of the figure enclosed under v-t graph. Distance covered in 15s, s=ut=20×15=300m
