Centripetal force is the force that maintenance objects that are moving in a circular motion.
F = mv²/r
= (1500 × 16²)/100
= (1500×256)/100
= 384000/100
= 3,840 N
2) F = (mv²)/r
6000 N = (1200 × 20²)/r
r = (1200 × 400)/6000
= 480,000/6000
= 80 m
Answer - An object is in motion when its distance from another object is changing. ... A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. You assume that the reference point is stationary, or not moving.
Answer:
14.57 ohms
Explanation:
Here in the figure ,Rb & R₄are in series & also Rc & R₅ are in series. As they are in series , ( Rb + R₄ ) & (Rc & R₅) are in parallel . So the equivalent resistance in that branch = ( 2 + 18 ) ║ ( 3 + 12 )
= 20 ║ 15
= (20×15) / (20 + 15)
= 8.57 ohms
Also Ra ( 6 ohm ) is in series with that branch ,. So the equivalent resistance of the whole circuit = 8.57 + 6 = 14.57 ohms.
All isotopes contain different number of neutrons then the original element
