This is an incomplete question, here is a complete question.
The bulk modulus for bone is 15.0 (GPa). If a diver-in-training is put into a pressurized suit, by how much would the pressure have to be raised (in atmospheres) above atmospheric pressure to compress her bones by 0.130% of their original volume?
Answer : The change in pressure will be,
Explanation : Given,
Bulk modulus =
Change in volume = 0.130 % of original volume
Let the original volume be, V
So, Change in volume =
Formula used for change in pressure is:
Now put all the given values in this formula, we get:
Thus, the change in pressure will be,
Answer:
v_max = (1/6)e^-1 a
Explanation:
You have the following equation for the instantaneous speed of a particle:
(1)
To find the expression for the maximum speed in terms of the acceleration "a", you first derivative v(t) respect to time t:
(2)
where you have use the derivative of a product.
Next, you equal the expression (2) to zero in order to calculate t:
For t = 1/6 you obtain the maximum speed.
Then, you replace that value of t in the expression (1):
hence, the maximum speed is v_max = ((1/6)e^-1)a
