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.

3. If you were in a car collision, would you rather be hit by Vehicle 1 (2,027 kg) or Vehicle 2 (1,415 kg) from Activity 73? Explain.
Answer:
I say vehicle one, because both will apply the same amount of force but, because vehicle two has less mass, it will accelerate more rather than vehicle one which will accelerate less.
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.
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.

Suppose the Sun is 1.29025 X 108 km from
Earth.
The speed of light is 2.99792 x 108 m/s.
How long does it take for its light to reach
us?
Answer in units of min.
Answer:
It takes the Sun's light 7.17 minutes to reach us.
Explanation:
We can calculate the time that takes the light to reach us by using the following equation:
[tex] t = \frac{d}{c} [/tex]
Where:
d: is the distance = 1.29025x10⁸ km = 1.29025x10¹¹ m
c: si the speed of light = 2.99792x10⁸ m/s
Hence, the time is:
[tex] t = \frac{d}{c} = \frac{1.29025 \cdot 10^{11} m}{2.99792 \cdot 10^{8} m/s} = 430.38 s = 7.17 min [/tex]
Therefore, it takes the Sun's light 7.17 minutes to reach us.

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

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.

Use newton's law to explain the vertical acceleration of a projectile
Answer:
Explained below
Explanation:
Newton's first law of motion: This law states that an object will remain at rest or continue in constant motion except it's acted upon by an external force. In projectile motion, the horizontal component of velocity will remain unchanged because we ignore air resistance since no force is acting in that horizontal direction.
Newton's second law of motion: This law states that force is the product of mass and acceleration. In projectile the force acts downwards, thus f = mg.
But g = a since internal forces will cancel out.
Thus, F = ma

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]
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

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.

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.
