Why do we not feel air pressure?
Answer:
Explanation:
Is beacuse of the air within our bodys is exerting the same pressure out wards so tjere is no pressure difference
Answer:
it is because our body itself is not adept enough to resist the air pressure. For every reaction, there be an balanced opposite reaction according to Newton's law. namely, all forces such as air pressure are in proportion therefore we will not perceive air pressure which also means no net force.

An object is placed 110 mm from a concave mirror with a focal length of 5.0 cm.
Answer:
Approximately 92 mm.
Explanation:
Object's distance, u = 110 mm = 11 cm
focal length of the mirror = 5 cm
Image distance, v = ?
To determine the image distance, apply the mirror's formula;
[tex]\frac{1}{f}[/tex] = [tex]\frac{1}{u}[/tex] + [tex]\frac{1}{v}[/tex]
[tex]\frac{1}{v}[/tex] = [tex]\frac{1}{f}[/tex] - [tex]\frac{1}{u}[/tex]
= [tex]\frac{1}{5}[/tex] - [tex]\frac{1}{11}[/tex]
= [tex]\frac{11-5}{55}[/tex]
[tex]\frac{1}{v}[/tex] = [tex]\frac{6}{55}[/tex]
⇒ v = [tex]\frac{55}{6}[/tex]
= 9.166667
v = 9.2 cm
The image distance is 92 mm.

b...radio waves answer
Which form of electromagnetic radiation with a relatively high amount of energy is used to sanitize lab goggles?
Answer:
Gamma radiation.
Explanation:
Electromagnetic waves are waves produced with respect to the interaction of electric field and magnetic field. They can be arranged with respect to their increasing or decreasing wavelength to form a pattern called electromagnetic spectrum.
Gamma radiation can be used for sterilization purpose due to the fact that it has a relatively high amount of energy, and do not produce any characteristic radiation.
on what mass will a force 16N produce an acceleration of 160N
Answer:
m = 0.1 [kg]
Explanation:
To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration. In this way, we have the following equation.
[tex]F =m*a[/tex]
where:
F = force = 16[N]
a = acceleration = 160 [m/s²]
m = mass [kg]
Now replacing:
[tex]m=F/a\\m = 16/160\\m = 0.1 [kg][/tex]

Question 4 options: The steps that lead you from dependence to independence are referred to as The _________ to Lifetime Fitness, Health, and Wellness.
Answer:
Stairway.
Explanation:
The steps that lead you from dependence to independence are referred to as the stairway to Lifetime Fitness, Health, and Wellness.
This ultimately implies that, these stairway or steps are very important and essential for all humans who seek Lifetime Fitness, Health, and Wellness.
A good health can be defined as the state of well-being (wellness) in which all of the components of an individual's health are balanced. These state of wellness comprises of six (6) important components and they are;
1. Physical: this is a measure of the state of an individual's body or the way the body functions. It is enhanced by eating right, working out or exercising, avoiding drugs and alcohol, maintaining a good body mass index etc.
2. Emotional: this deals with the state of an individual's mind being void of worries, negativity etc.
3. Social: this involves keeping a good relationship with friends, family and many others around.
4. Environmental: it deals with maintaining a hygienic surrounding, that is devoid of pollutants.
5. Mental or intellectual: avoiding unnecessary stress and anxiety while dealing or coping with the realities of life.
6. Spiritual: it encompasses belief systems, values, ideals, morality etc.
Hence, when an individual is able to balance all of these above mentioned components, then he or she is said to be healthy.

A crane lifts an air conditioner to the top of a building. If the building is 12 m high, and the air conditioner has a mass of 200 kg, how much work did the crane do to lift it? (Hint: the force the crane exerts is equal to the weight of the air conditioner)
Work needed = 23,520 J
Further explanationGiven
height = 12 m
mass = 200 kg
Required
work needed by the crane
Solution
Work is the transfer of energy caused by the force acting on a moving object
Work is the product of force with the displacement of objects.
Can be formulated
W = F x d
W = Work, J, Nm
F = Force, N
d = distance, m
F = m x g
Input the value :
W = mgd
W = 200 kg x 9.8 m/s²x12 m
W = 23520 J

How much power did they exert climbing the stairs? answer choices . 400 W. 1200 W. 200 W. 120 W. Tags
200 W was used in climbing the stairs.
We'll begin by calculating the energy. This can be obtained as follow:
Mass (m) = 40 kg
Height (h) = 3 m
Acceleration due to gravity (g) = 10 m/s²
Energy (E) =? E = mghE = 40 × 10 × 3
E = 1200 JFinally, we shall determine the power exert in climbing the stairs. This can be obtained as follow:
Energy (E) = 1200 J
Time (t) = 6 s
Power (P) =?[tex]Power = \frac{Energy }{Time}\\\\Power = \frac{1200}{6}[/tex]
Power = 200 WThus, 200 W was used in climbing the stairs.

Famous French mathematician, physicist, and philosopher Blaise Pascal announced this law in the year 1647.
What is pascal law?According to this law, pressure applied to a liquid that is at rest is uniformly distributed throughout.
There are numerous uses for it in daily life. Numerous gadgets, like hydraulic lifts and brakes, are based on Pascal's law.
For incompressible fluids, Pascal's concept is applicable. The majority of vehicle repair shops using lifts use one common use. In essence, air from an air compressor is delivered to the top of oil in a container; the oil then exerts pressure on a sleeve or piston that raises the car.
Therefore, Famous French mathematician, physicist, and philosopher Blaise Pascal announced this law in the year 1647.

if a 50.0-kg mass weighs 554 n on the planet saturn, calculate saturn’s radius
Answer:
17.35 × 10^(-6) m
Explanation:
Mass; m = 50 kg
Weight; W = 554 N
Now, we know that;
W = mg
Thus; 554 = 50g
g = 554/50
g = 11.08 m/s²
Also, we know that;
mg = GMm/r²
g = GM/r²
Making t the subject gives;
r = √(GM/g)
G has a constant value of 6.67 × 10^(-11) Nm²/kg²
r = √(6.67 × 10^(-11) × 50/11.08)
r = 17.35 × 10^(-6) m
The radius of the saturn is [tex]\bold {17.35 x 10^{-6 }m}[/tex] if a 50.0-kg mass weighs 554 N.
From Newton's second law,
W = mg
554 = 50 x g
g = 554/50
g = 11.08 m/s²
Now, Newton's law of gravitation
[tex]\bold {F=G{\dfrac{m_1m_2}{r^2}}}[/tex]
Where,
F = force
G = gravitational constant = 6.67 x 10^-11 N.m²/kg²
m1 & m2= mass = M = 50 kg
r = distance between centers of the masses
Put the values and solve it for r,
[tex]\bold {r = \sqrt {(6.67 x10^{-11} \times \dfrac {50}{11.08}}}\\\\\bold {r = 17.35 x 10^{-6 }m}[/tex]
Therefore, the radius of the saturn is [tex]\bold {17.35 x 10^{-6 }m}[/tex] if a 50.0-kg mass weighs 554 N.

Scientists treat the number of stars in a given volume of space as a Poisson random variable. The density of our galaxy in the vicinity of our solar system is 3 stars per 10 cubic light-years. What is the probability of one or more stars in 10 cubic light-years? Round your answer to 4 decimal places.
Answer:
[tex]P(X\ge 1) = 0.9502[/tex]
Explanation:
Given
Density = 3 starts in 10 cubic light years.
Required
Determine the probability of 1 or more in 10 cubic light years
Since the number of stars follow a Poisson distribution, we make use of:
[tex]P(X=k) = f(x) = (\lambda T)^k\frac{ e^{-\lambda T}}{k!}[/tex]
[tex]\lambda = density[/tex]
[tex]\lambda = \frac{3}{10}[/tex]
[tex]\lambda = 0.3[/tex]
T = the light years
[tex]T = 10[/tex]
Calculating [tex]P(X \ge 1)[/tex]
In probability:
[tex]P(X \ge 1) = 1 - P(X = 0)[/tex]
Calculating P(X=0)
Substitute 0 for k and the values for [tex]\lambda[/tex] and T in
[tex]P(X=k) = f(x) = (\lambda T)^k\frac{ e^{-\lambda T}}{k!}[/tex]
[tex]P(X=0) = (0.3* 10)^0 * \frac{ e^{-0.3 * 10}}{0!}[/tex]
[tex]P(X=0) = (3)^0 * \frac{ e^{-0.3 * 10}}{1}[/tex]
[tex]P(X=0) = (3)^0 * e^{-0.3 * 10}[/tex]
[tex]P(X=0) = 1 * e^{-0.3 * 10}[/tex]
[tex]P(X=0) = 1 * e^{-3}[/tex]
[tex]P(X=0) = e^{-3}[/tex]
[tex]P(X=0) = 0.04979[/tex]
Substitute 0.04979 for P(X=0) in [tex]P(X \ge 1) = 1 - P(X = 0)[/tex]
[tex]P(X\ge 1) = 1 - 0.04979[/tex]
[tex]P(X\ge 1) = 0.95021[/tex]
[tex]P(X\ge 1) = 0.9502[/tex] --- approximated
Hence, the required probability is 0.9502
