Explain why people who use the drug in the following scenario might have potential health risks.

Steve is a principal investigator at Live Pharmaceuticals, Inc., and is working on a new drug. He tells a coworker, “Never mind the exact content of the essential ingredient. The ingredient quality does not matter. Just ensure the drug doesn’t exceed the weight limit.”

For this we have the hidrostatic equation:

[tex]\boxed{P = \rho gh}[/tex]

Being:

P = Pressure

ρ = Density of liquid (water) = 1000 kg/m

g = Gravity = 9,81 m/s²

h = Height = 4 m

Replacing acording formula:

[tex]\boxed{P = 1000 \ kg/m ^{3} * 9,81 \ m/s^{2} * 4 \ m}[/tex]

Resolving:

[tex]\boxed{P = 39240 \ Pa}[/tex]

To solve this problem, we apply the kinetic energy formula;

        K.E  = [tex]\frac{1}{2}[/tex] m v²  

m is the mass

v is the unknown

 Now, insert the parameters and solve;

        484  = [tex]\frac{1}{2}[/tex] x 8 x v²

        484  = 4v²

           v² = 121

            v  = 11m/s

The end of the detergent molecule which attaches to fat (grease) repels water molecules. It is known as hydrophobic, meaning "water fearing." By attempting to move away from the water molecules, the hydrophobic ends of the detergent molecules push up to the surface. This weakens the hydrogen bonds holding the water molecules together at the surface. The result is a break in the surface tension of the water.

Answer:

In a soap-and-water solution the hydrophobic (greasy) ends of the soap molecule do not want to be in the liquid at all. Those that find their way to the surface squeeze their way between the surface water molecules, pushing their hydrophobic ends out of the water. This separates the water molecules from each other.

The study of the physical properties of light, such as its wavelength and amplitude, and the human perception of color is called psychophysics. It comprises two major areas: discrimination and absolute.

The study of wavelength and amplitude, interaction between physical stimuli and their consequential effects such as perceptions and sensations is called psychophysics.

This concept is applied in psychophysics tasks where extensive research and studies are performed on sensory and other visual information.

To put it in simple words, psychophysics is vital for measuring the perception of a subject through stimulus detection experiments.

Stimuli detection is done either through the method of limits, adjustment technique, or constant stimuli method.

Answer:

The displacement of the object is -8 m

Explanation:

Displacement

The displacement of a moving object can be calculated as the area under (or above) the graph of velocity vs time.

If the area is below the y-axis, then the displacement is negative. Otherwise is positive.

It's important to differentiate displacement from distance. Displacement takes into consideration the direction of the movement. Distance does not and it's always positive.

From the graph provided, we can see the velocity from t=12 s from t=16 s is negative, and the displacement will also be negative.

The displacement is calculated as the area of the triangle with base b=16-12= 4 seconds and height = -4 m/s, thus:

[tex]\displaystyle D = \frac{4*(-4)}{2}=-\frac{16}{2}=-8\ m[/tex]

Answer:

Gravitational potential energy and Elastic potential energy

Explanation:

The two types of potential energy the springs described in the question have are Gravitational potential energy and Elastic potential energy.

Firstly, it must be noted that potential energy is the energy stored/present in a stationary (non-moving) object (or object at rest).

Gravitational potential energy is the potential energy as a result of the vertical position of an object due to force of gravity acting to pull it down. The gravitational potential energy is as a result of the springs been attached to the ceiling which causes the force of gravity to want to pull it down. This gravitational force is further increased when the swing is attached causing the weight of swing to act in the direction of the force of gravity.

Elastic potential energy is the potential energy stored in an elastic object or energy stored in an object that can be stretched or compressed. This is the energy that would always be found in a spring, so when the springs have been attached to the ceiling and the swing has been fastened to them, there elastic potential energy would reduce as a result of the kinetic energy that must have been used to stretch the springs.

Answer:

5000 J

Explanation:

W=F*D

W=500N*10m

w=5000 J

When a man applies a force of 500 N to push a truck 10 m down the street. Then the work of 5000 J has been done.

Work done is the amount energy gained (loosed) in bringing the body from initial position to final position. It is denoted by W and its SI unit is joule(J). i.e. Work(W) is force(F) times displacement(s). W=F× s When a body is displaced with 1 newton of force by 1 m, then we can say that work has been done on the body by 1 joule.

Writing for it's dimension, W=F× s

Force has dimension [L¹ M¹ T²]

Displacement has dimension [L¹]

multiplying both the dimensions Force and Displacement we get, dimension of Work [L² M¹ T²].

Given,

F = 500 N

s = 10 m

Work = Fs = 500×10 = 5000 J

(a) The height reached by cat A is 2.5 m.

(b) The speed of cat A before it hits the ground is 36.4 m/s.

(c) The speed of cat B before it hits the ground is 22.39 m/s.

(d) The time spent in air by cat A than cat B is 1.43 seconds.

The time of motion of cat A is calculated as follows;

h = vt - ¹/₂gt

-23 = 7t - 4.9t²

4.9t² - 7t - 23 = 0

solve the quadratic equation using formula method;

a = 4.9, b = -7, c = - 23

t = 3.0 seconds

The time of motion of cat B is calculated as follows;

h = vt - ¹/₂gt

23 = 7t + 4.9t²

4.9t² + 7t - 23 = 0

solve the quadratic equation using formula method;

a = 4.9, b = 7, c = -23

t = 1.57 seconds

h = u²/2g

h = (7²)/(2 x 9.8)

h = 2.5 m

v = u + gt

v = 7  + 3(9.8)

v = 36.4 m/s

v = u + gt

v = 7  + 1.57(9.8)

v = 22.39 m/s

Time difference = 3 s - 1.57 s = 1.43 seconds

Thus, the height reached by cat A is 2.5 m.

The speed of cat A before it hits the ground is 36.4 m/s.

Answer:

It emits beta particles and gamma rays.

Explanation:

The correct answer is 19.7 m/s.

Range is the height of the projectile when it reaches a vertical velocity of zero; after that, gravity will take over and quicken the object's descent. The projectile range, which is determined by the object's initial velocity, is the horizontal displacement of the object projected.

Only when one force is applied at the start of the trajectory does projectile motion occur; thereafter, gravity is the only resistance. A projectile launched under specified beginning circumstances will have a range in physics. Assuming a flat Earth with a consistent gravity field and no air resistance may make it more predictable.

Range R = 38.7 m

Acceleration due to gravity g =9.8 m/s

Launch angle θ = 51

Range of the projectile is given by

R = [tex]u^2[/tex] Sin2θ / g

[tex]u^2[/tex] = gR/ Sin 2θ

u = √gR/ Sin 2θ

u = √ 9.8 × 38.7 / Sin ( 2 × 51)

u = 19.7 m/s.
