Given :
Pilot sits 2.19 m from the center of rotation.
Horizontal centripetal acceleration is 65.8 m/s².
To Find :
The angular velocity of the pilot .
Solution :
We know, centripetal acceleration is given by :
[tex]a = \omega^2 r\\\\\omega = \sqrt{\dfrac{a }{r}}\\\\\omega = \sqrt{\dfrac{65.8 }{2.19}}\\\\\omega = 5.48\ s^{-1}[/tex]
Hence, this is the required solution.

[tex] \frac{1}{(1 - \sqrt{3) {}^{2} } } [/tex]
Answer:
\frac{2+\sqrt{3}}{2}
Explanation:
so we simplify tthe denominator first
[tex](1-\sqrt{3})^2=[/tex][tex]4-2\sqrt{3}[/tex]
so the new fraction is:[tex]\frac{1}{4-2\sqrt{3}}[/tex]
We'll ratinalize the fraction to get: [tex]\frac{2+\sqrt{3}}{2}[/tex]

Explanation:
A Chevy Camaro drives straight off the top level off a parking garage at 13 m/s. If the car landed 90 meters away from the base of the parking garage, how high (height) was the top level?
Answer:
H = 234.85m
Explanation:
Using the formula for calculating range to find the maximum height
Range R = U√2H/g
U is the speed = 13m/s
H is the max height
R is the distance covered in horizontal direction
g is the acceleration
Substitute the given values as shown;
90 = 13√2H/9.8
90/13 = √2H/9.8
6.923 = √2H/9.8
6.923² = 2H/9.8
2H = 6.923² * 9.8
2H = 469.70
H = 469.70/2
H = 234.85m
Hence the top level was 234.85m high

The voltage between two points in a circuit is 4.2 V. If the resistance between
the points is 72, what is the current, according to Ohm's law?
A. 0.058 A
B. 76.2 A
O C. 17.1 A
O D. 302 A
Answer:
I = 0.058 [A]
Explanation:
Ohm's law is defined as voltage equal to the product of current by resistance.
[tex]V =I*R[/tex]
where:
V = voltage = 4.2 [V]
I = current [amp]
R = resistivity = 72 [ohm]
Now clearing I, we have:
[tex]I = V/R\\I = 4.2/72\\I = 0.058 [A][/tex]
Answer:
A. 0.058 A

Jake and Amir are both standing on identical skateboards and
perform a physics experiment in which they push off one
another to move. Jake is taller and more massive than Amir. If
Jake pushes with 20 N of force, what force would he feel
backwards away from Amir? F= N
Answer: 20
Explanation:
If Jake pushes with 20 N of force, the force that he would feel backwards away from Amir is 20N
Force simply means the strength or energy that can later the position of an object. Force can also be described as a push or pull.
It should be noted that since Jake pushes with 20 N of force, the force that he would feel backwards away from Amir will be the exact force that was used in pushing.
This will therefore be 20 Newton as well.

Two students are studying for a Science Test. On the table, they had a glass of water and identical cell phones. Both of their phones had run out of battery, therefore they were both charging in the same wall outlet. One student’s charging cord was 3ft and the other student’s charging cord was 9ft. which of the phones charged the fastest using Ohm’s Law. Cite evidence to support your theory.
Answer:
The student with the 3ft charger
Explanation:
Because the electricity from the 3ft charger has a shorter distance to mooves than the 9ft one

What factors determine the distance at which two atoms form a bond ?
Answer:
The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.

At the local destruction derby a 400 kg Toyota moving at 10 m/s collides with an 800 kg Chevy. Both are at rest after the collision. What was the velocity of the Chevy before the collision?
Answer:
[tex]u_2 = -5m/s[/tex]
Explanation:
Given
Before Collision
Toyota
[tex]mass = m_1 = 400kg[/tex]
[tex]iniital\ velocity = u_1 =10m/s[/tex]
Chevy
[tex]mass = m_2=800kg[/tex]
[tex]initial\ velocity = u_2 = ??[/tex]
After Collision
Both Toyota and Chevy
[tex]final\ velocity = v = 0m/s[/tex]
Required
Determine the initial velocity of Chevy
This question will be answered using the following law of conservation of momentum which states that:
[tex]m_1u_1 + m_2u_2 = (m_1 + m_2)v[/tex]
Substitute values for m1, m2, u1 and v
[tex]400 * 10 + 800 * u_2 = (400 + 800) * 0[/tex]
[tex]4000 + 800u_2 = (1200) * 0[/tex]
[tex]4000 + 800u_2 = 0[/tex]
Collect Like Terms
[tex]800u_2 = 0 - 4000[/tex]
[tex]800u_2 = -4000[/tex]
Divide through by 800
[tex]\frac{800u_2 = -4000}{800}[/tex]
[tex]u_2 = \frac{-4000}{800}[/tex]
[tex]u_2 = -5m/s[/tex]
The velocity of Chevy before collision was 5m/s in the opposite direction of Toyota

What is the period of a rotating object if it spins 24 times in 13 seconds?
Answer:
The period is 0.54 seconds
Explanation:
Period (T)
Is the time required for a rotating object to make one complete revolution around a circular path.
If it takes a time t to complete n revolutions, the period is:
[tex]\displaystyle T=\frac{t}{n}[/tex]
The rotating object spins n=24 times in t=13 seconds, thus its period is:
[tex]\displaystyle T=\frac{13}{24}[/tex]
T = 0.54 sec
The period is 0.54 seconds

A box is sitting stationary on a long level ramp on level ground. The coefficient of static friction is (1.0). One end of the ramp is slowly lifted higher and higher. What is the angle of the ramp with respect to the ground when the box begins slidig?
Answer:
45 degrees
Explanation:
Given that the coefficient of friction, [tex]\mu=1.0[/tex]
Let the angle of the ramp be [tex]\theta[/tex].
The gravitational force acting downward [tex]=mg[/tex]
The normal reaction by the ramp on the box, [tex]N=mg\cos\theta[/tex]
So, the maximum frictional force that can act on the box, [tex]f= \mu N[/tex]
The force along with the plane in the direction of sliding, [tex]F = mg\sin\theta[/tex]
When the box begins sliding, the F must have to overcome the frictional force,f.
So, F=f
[tex]mg\sin\theta=\mu N \\\\mg\sin\theta=\mu mg\cos\theta \\\\\frac {\sin\theta}{\cos\theta}=\mu \\\\\tan\theta=\mu \\\\\theta=\tan^{-1}\mu \\\\[/tex]
Putting the value of \mu, we have
[tex]\theta=\tan^{-1}1[/tex]
[tex]\theta=45[/tex] degrees.
Hence, the angle of the ramp with respect to the ground when the box begins sliding is 45 degrees.
Our atmosphere exerts a pressure of 14.7 lb/in2. What is the force on one square foot of the earth’s surface caused by the atmosphere
Answer:
The force on one square foot of the earth’s surface caused by the atmosphere is 101.4 kN.
Explanation:
To force is given by:
[tex]F = P*A[/tex] (1)
Where:
P: is the pressure = 14.7 lb/in²
A: is the area = 1 m²
By entering the above values into equation (1) we have:
[tex]F = P*A = 14.7 \frac{lb}{in^{2}}*\frac{4.45 N}{1 lb}*\frac{1550 in^{2}}{1 m^{2}}*1 m^{2} = 101.4 kN [/tex]
Therefore, the force on one square foot of the earth’s surface caused by the atmosphere is 101.4 kN.

Studying neutrinos helped to explain how our Sun works but led to changes in theories of particle physics, how is this process consistent with the scientific process? How can details about a theory be adjusted without undermining other discoveries made through the theory's predictions?
Explanation:
Yes, evidently, the process is consistent with the scientific process because in scientific process falsification and modification are two very important traits. So this new concept have modified the existing theories.
Through the modification a theory is adjusted without undermining other discovering made through the theory's prediction.
There are many other evidences that prove this fact for example Einstien's Theory of relativity also changes the existing concepts.
