Uranium-238 undergoes alpha decay. Therefore, uranium-238 will
A. Remain stable
B. Stay the same element
C. Release charged particles and no energy
<u>D. None of the above</u>
The actual answer is that it will change into a different element altogether.
The first force has magnitude 60 N and makes an angle of -30° relative to the positive horizontal axis (i.e. to the immediate right), while the second force has magnitude 150 N and direction +30° from the horizontal.
In component form, we have
The resultant force is the vector
Its magnitude is
Its direction is such that
Because the components of the resultant force are both positive, that means the angle makes with the horizontal is between 0° and 90°. So
