The longitude based on the time difference is 15 degrees.

<h3>Longitude of complete rotation of the Earth</h3>

The longitude of a complete rotation of the earth in a 24 hours is calculated  as follows;

= \frac{360^0}{24} = 15^0 \ of \ longitude

<h3>Time difference</h3>

The time difference between the local apparent solar time and the Greenwich time is calculated as follows;

t = 12 pm \ - \ 11 am\\\\t = 1 \ hour

Since it is one hour time difference, the longitude is 15 degrees.

Two trains, each having a speed of 28 km/h, are headed at each other on the same straight track. A bird that can fly 60 km/h fli
Semenov [28]

Answer:

The value is D =  70.71 \ km

Explanation:

From the question we are told that

The speed of each train is v =  28 \  km/h

The speed of the bird is v_1 =  60 \  km/h

The distance between the trains is d =  66 \  km

Generally the time taken before the collision occurs is mathematically represented as

t =  \frac{d}{2 * v}

=> t =  \frac{66 }{2 *  28}

=> t = 1.18 \  h

The total distance covered by the bird is mathematically represented as

D =  v_1 *  t

=>   D =  60 * 1.18

=>   D =  70.71 \ km

What has alternating electric and magnetic fields that travel in the form of a wave?
8_murik_8 [283]

Option (B)is correct.

Alternating electric and magnetic fields has electromagnetic radiation that travel in the form of a wave.

The varying or alternating electric field produces the varying magnetic field.This varying magnetic field in turn produces varying electric field . Thus these varying electric and magnetic fields travel in the form of electromagnetic waves. These electromagnetic waves travel with the velocity of light.These are transverse in nature.
