By the way . . . . . The question is wrong, wrong, wrong.
When you jump up from Earth, the Earth DOES jump backwards away from you.
The wavelength of the light can be calculated by dividing the speed of light by its frequency. Since both the speed of light and the frequency are given, we simply just need to perform a simple calculation.
ANSWER: D.
I believe 2 is the midpoint
Answer:
Explanation:
Since we know that the displacement of the boat in the direction of flow of the river must be zero
so we have to at such an angle with shore so that the component of velocity of boat along the direction of flow must be equal and opposite to the flow velocity of the water
so we will have
Now the resultant velocity of the boat is in perpendicular to the flow of water
so we will have
Both NPN and PNP transistors consist of a base composed of an N-type material.
