Answer:

13.28 km

Explanation:

The bird flies from the runner, to the finish line, and back to the runner. We can write two equations for the distance it travels:

d = 8.3 km + 8.3 km − 8.6 km/hr × t

d = 34.4 km/hr × t

Solve for t in the second equation and substitute into the first:

t = d / 34.4

d = 8.3 + 8.3 − 8.6 (d / 34.4)

d = 16.6 − 0.25 d

1.25 d = 16.6

d = 13.28

The bird flies a cumulative distance of 13.28 km.

saveliy_v [14]

Answer with Explanation:

We are given that

Magnetic field,B= $0.6\times 10^{-4} T$

$\theta=75^{\circ}$

Length of wire,l=15 m

Current,I=19 A

a.We have to find the magnitude of magnetic force and direction of magnetic force.

Magnetic force,F= $IBlsin\theta$

Using the formula

$F=0.6\times 10^{-4}\times 15\times 19sin75$

$F=16.5\times 10^{-3} N$

Direction= $tan\theta=cot(90-75)=tan15^{\circ}$

$\theta=15^{\circ}$

15 degree above the horizontal in the northward direction.
