Answer:
123 km/h
Explanation:
The distance between the Jeep Wrangler and the Ford Taurus is increasing.
Let us consider the north direction as positive when observing from the ground
So, the south direction will be negative
But when the observer is one of the cars the direction will be the same i.e., moving away from each other, so the velocity will be added.
Hence velocity of the Jeep relative to the Ford will be
Velocity of the Jeep + Velocity of the Ford
= 74+49 = 123 km/h
∴ Velocity of the Jeep relative to an observer in the Ford is 123 km/h
a. subduction.
Explanation:
A subduction zone is a zone where the oceanic crust dives beneath the continental crust.
- Subduction zones are typical features of convergent margins where two plates pulls together.
- They are formed by continent-oceanic covergence and ocean - ocean covergence.
- In oceanic - continent convergence, the denser oceanic crust slides under the continental crust because it is denser than the mantle below.
- In oceanic - oceanic crust convergence, either of the plate slides under the other into the mantle.
- Trenches, volcanoes, earthquakes are typical geologic features associated with them.

Answer:
Explanation:
Let us assume that the radius of the wire, r = 0.8 mm = 0.0008 m
EMF of the battery, V = 12 V
Slope of I versus 1/d, m = 600 A-m
The resistance of any material is given by :
d is the length of wire
Since,
So, the resistivity of the material of which the wire is made is .
The statemengt is <em>false</em>. Electromgnetic waves do not require a medium to transfer energy. They can transfer energy through vacuum (empty space with nothing in it). If electrimagnetic waves needed a medium to move through from place to place, then we could never see the sun, and also it would get very cold here.
