C
As there have current goes through the circuit and current will induce magnetic field
Height of one roof is 5.97 m below the other roof
now its displacement in vertical direction is given as
solving above for time
now in the same time cat has to cover the distance between two buildings
so here we can say
solving above for speed
so speed of cat is 6.54 m/s
Answer:
An interaction of one object with another object results in a force between the two objects. Thus, at-least two objects must interact for a force to come into play.
If there's no air resistance, then the diver keeps moving horizontally at 40 m/s, even after s/he jumps out of a perfectly good airplane.
Also, gravity ADDS 9.8 m/s of downward speed for every second the diver falls.
One second after leaving the airplane, the diver is moving horizontally at 40 m/s, and moving vertically downward at 9.8 m/s .
The question asks for the "downward velocity". That's 9.8 m/s .
The diver's TOTAL velocity is
√ (40² + 9.8²)
= √ (1,600 m²/s² + 96.04 m²/s²)
= √ (1,696.04 m²/s²)
= 41.2 m/s in some direction between
straight forward and straight down.
