The electromagnetic spectrum is the range of all types of radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays.

The route followed by a hiker consists of three displacement vectors A with arrow, B with arrow, and C with arrow. Vector A with
kotykmax [81]

Answer:

D_{B}=1173.98m\\D_{C}=675.29m

Explanation:

If we express all of the cordinates in their rectangular form we get:

A = (1404.77 , 655.06) m

B = A + ( -D_{B} *sin(41) , -D_{B} * cos(41) )

C = A + B + ( -D_{C} *cos(20) , D_{C} * sin(20) )

Since we need C to be (0,0) we stablish that:

C = (0,0) = A + B + ( -D_{C} *cos(20) , D_{C} * sin(20) )

That way we make an equation system from both X and Y coordinates:

A_{x} + B_{x} + C_{x} = 0

A_{y} + B_{y} + C_{y} = 0

Replacing values:

1404.77 - D_{B}*sin(41) - D_{C}*cos(20) = 0

655.06 - D_{B}*cos(41) + D_{C}*sin(20) = 0

With this system we can solve for both Db and Dc and get the answers to the question:

D_{B}=1173.98m

D_{C}=675.29m

The runner reaches the first camera, at the 500 m mark, at 9:03:05 a.m. and the second camera, at the 600 m mark, at 9:03:25 a.m
SVEN [57.7K]

Answer:

Explanation:

Distance travelled = 600 - 500 = 100 m

Time taken = 9:03:25 a.m.-  9:03 :05 a.m.

= 20 s

average speed = distance / time taken

= 100 / 20 m /s

= 5 m /s
