Answer:
Explanation:
If two forces act on an object in the same direction, the net force is equal to the sum of the two forces.
Answer:
Explanation:
Following relation exists between number of turns and volt
Volt in primary / volt in secondary = no of turns in primary / no of turns in sec
19000 / 120 = no of turns in primary / 159
no of turns in primary = 19000 x 159 / 120
= 25175 Ans .
Where’s the picture we can’t see a picture
27) Velocity and time
28) it indicates increasing velocity
29) It is moving in constant velocity which means no acceleration.
Answer:
V2 = (V1 - u) / (1 - V1 u / c^2)
V1 = speed of ship in observer frame = .99 c to right
u = speed of frame 2 = -.99 c to left relative to observer
V2 = speed of V1 relative to V2
V2 = (.99 - (-.99 ) / (1 - .99 (-.99)) c
V2 = 1.98 / (1 + .99^2) c = .99995 c
