Answer:
In order to hit the same point with the second ball, you should throw it at an angle of 18° above the horizontal.
Explanation:
Horizontal reach formula for projectiles tells us
where is the initial velocity and the angle above the horizontal.
Since for both shots the reach must be the same, we have
.
Answer:
the question has some missing details i.e E = E0sin(kx -wt)y and B = B0sin(kx -wt)z
The variables E0 and B0 are the amplitudes.
option C is correct.
Explanation:
Compare the equation given with the general wave equation ; Y = Asin(kx - wt)
Where A is the amplitude
I believe the sun is the primary source of energy for Earth's weather system. The sun is the primary energy source for Earth's climate system which is the first set of essential principles of climate sciences. Additionally, it is the primary source that drives all weather events, including precipitation, hurricane and tornadoes. The sun drives the hydrologic cycle, and makes life on Earth possible.
