When two plates come together, it is known as a convergent boundary.Magma from the mantle solidifies into basalt, a dark, dense rock that underlies the ocean floor. Thus at divergent boundaries, oceanic crust, made of basalt, is created. Two plates sliding past each other forms a transform plate boundary.
Answer:
s = 3.84 x 10⁸ m
Explanation:
The distance traveled by an object, while in uniform motion, is given by the following equation:
s = vt
where,
s = distance covered
v = speed
t = time interval
In this case:
s = distance between Moon and Earth = ?
v = speed of radio waves = 3 x 10⁸ m/s
t = time taken to travel = 1.28 s
Therefore,
s = (3 x 10⁸ m/s)(1.28 s)
<u>s = 3.84 x 10⁸ m</u>
Answer:
(A) 12.222 ohm (B) 990 W
Explanation:
We have given the voltage of the heating element V = 110 V
The current in the heating element i = 9 A
(a) According to ohm's law V =iR
So 
(b) The power dissipated in the resistor is given by 
So the power dissipated = 990 W
Answer:
hide on a place where there is no windows take a radio
Explanation:
In optics, a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams travelling in different directions.
