Answer:
(a) A = m/s^3, B = m/s.
(b) dx/dt = m/s.
Explanation:
(a)
Therefore, the dimension of A is m/s^3, and of B is m/s in order to satisfy the above equation.
(b)
This makes sense, because the position function has a unit of 'm'. The derivative of the position function is velocity, and its unit is m/s.
0.10 x 200 = 20 mm 0.20 x 2 is 0.40 mm. so the book would be 20.4 mm thick
The correct answer is “C” ultrasound. Hope this helps!
