Answer:
4.55 minute
Explanation:
51 km = 51000 m
the ray of light travels due east 51000 m , bounces back from reflecting mirrors . The reflected light gets focused on a point 135 m south . Let the angle between incident light and reflected light be θ.
tanθ = 135 / 51000
θ = .1516 degree
= .1516 x 60 minute
= 9.09 minute
angle between incident ray ( east - west ) and normal = 9.09 / 2
= 4.55 minute Ans
Is there a picture of the car you can attach? That would help me to be able to answer the question :-)
Answer:
because the light bounces off of the water creating a bend. the answer is d.
The first wave that forms when the wind begins to blow across the ocean surface is a <u>capillary wave</u>
The capillary waves represent the initial state of a wave that are produced by vortices in a flat sea. When the winds blow over an ocean, energy is transferred from the wind to the sea. and that produced the waves. They are also presented as ripples.
The capillary waves have a wavelength less than 1.7 cm or 0.68 inches and its speed of 0.2 to 0.3 meter per second.
<h3>What is a capillary wave?</h3>
It is a wave that is travelling along the interface boundary of a fluid and it is influenced by the effect of surface tension and the gravity.

Answer:
Resistor
Explanation:
Resistor provides resistance to the flow of electric current in a circuit.
It controls the amount of current in a circuit by acting as a barrier to the flow of electric charges
