It would depend on the amount it would be still or crushed<span />
Before collecting a specimen of urine or feces, the nursing assistant asks the nurse or consults the lab for which storage and delivery method to use.
There are different tests that need to be performed on a urine or feces specimen. It depends on the patients that which test would be asked for him to be done.
The storage and delivery methods for urine and feces in the case of different tests has to be consulted by the nurse or consultant.
Incase of an emergency test, whose results are immediately required the method of delivery is a fast mode one. For patients that have a mild disease or are not at risk, other reliable methods can be used. Each specimen should be properly labeled for proper checking.

What are Sound Waves ?</h3>
Sound waves are longitudinal. That is, the direction of the waves is parallel to the direction of its propagation of particles.
Given that a boy finds an abandoned mine shaft in the woods, and wants to know how deep the hole is. He drops in a stone, and counts 4 seconds before he hears the "plunk" of the stone hitting the bottom of the shaft.
- The speed of the sound V = 330m/s
- The time it takes the sound to reach the top = t
Speed V = distance / time
330 = h/t
Make t the subject of formula
t = h/330
As the stone is dropped, initial velocity = 0, Using the formula
h = 1/2gT²
But T = 4 - t
T = 4 approximately
Substitute all the parameters
h = 1/2 × 9.8 × (4)²
h = 4.9 × (16)
h = 78.4m
Therefore, the shaft is 78m approximately deep. The correct option is D which is 78 meters

Answer:
T = 3.475 s
Time period is independent from mass
Explanation:
- To reduce the human error in taking any measurements we take multiple N number of readings. Then sum up all the readings and divide by N to find an average. The error between each individual reading and the actual reading is reduced by repetition.
- We use the plot of T^2 against L to form a linear relationship between two variables. We square the entire the equation for linearize the equation.
- Given, L = 3 m . The time period is approximated by a pendulum expression given as:
T = 2*pi*sqrt ( L / g )
Where, g is the gravitational acceleration 9.81 m/s^2
- Then we have:
T = 2*pi*sqrt ( 3 / 9.81 )
T = 3.475 s
- From above expression we see that time period is independent from the mass at the end of the string but a function of pendulum geometry and kinetics.
Angle of incidence is the angle when the light strikes an object while angle of reflection is the angle produced when the light strikes off/reflects from the object.
The relation between these two is that both the angles are equal.
The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
Hope this helps!
