Answer:
Part a)
Angle in degree is given as
Part b)
Size of the object is
Explanation:
Part a)
As we know that
180 degree = radian
so we have
so we have
Part b)
As we know that the relation of angle with radius is
The property that compares the mass of an object with its volume is density.
Just took the test and D: Standing Wave is the answer! :)
You can solve for acceleration by using the equation a=d/t
The third option (a=d/t) is correct because it is the only formula that solves for a, which stands for acceleration.
Hope this helped!
