Gases can do that. A gas takes the shape and volume of anything you put it in.

Which of the following statements regarding heuristics and empiricism is true? A. Heuristics allows a priori theoretical concep

WITCHER [35]

Answer: <em>Option (A) is correct.</em>

Explanation:

A heuristic is often referred to as an approach to solving problems or discovery that subjects a method, which is considered to be practical although might not be guaranteed to be perfect, optimal, or rational, but sufficient for reaching to goal.

Empiricism is known as a theory under which one can states that knowledge can only be imparted from the sensory experience. It is considered to be one of the main notions underlying in epistemology, i.e. known as the study of human knowledge, alongside skepticism and rationalism.

(b) Suppose oil spills from a ruptured tanker and spreads in a circular pattern. If the radius of the oil spill increases at a c

andreyandreev [35.5K]

Answer:

$\frac{dA}{dt} \approx 245.044\,\frac{m^{2}}{s}$

Explanation:

The formula for the surface of the circle is:

$A(r) = \pi\cdot r^{2}$

The rate of change of the spill area is obtained by deriving the previous formula in terms of time:

$\frac{dA}{dt} = 2\pi\cdot r\cdot \frac{dr}{dt}$

Finally, variables are replaced by known data:

$\frac{dA}{dt} = 2\pi\cdot (39\,m)\cdot (1\,\frac{m}{s} )$

$\frac{dA}{dt} \approx 245.044\,\frac{m^{2}}{s}$

"how long would it take for a ball dropped from the top of a 400-foot building to hit the ground? round your answer to two decim

Lelechka [254]

Hello

Let's convert first the height from foot to meters:
$S=400~ft=121.92~m$
This is the space covered by the ball in its accelerated motion, where the acceleration is the gravitational acceleration:
$a=g=9.81~m/s^2$
The law of motion is given by
$S= \frac{1}{2}at^2$
Re-arranging, we can get the total time of the motion:
$t= \sqrt{ \frac{2S}{a} }=4.99~s
$
which is the time the ball takes to hit the ground.
