The dot product of two vectors is a scalar quantity that only depends on the scalar product of the vectors' components, and not on the choice of reference frame.
The dot product of two vectors, v1 and v2, can be written as:
v1 · v2 = |v1||v2|cosθ
where |v1| and |v2| are the magnitudes of the vectors and θ is the angle between them. The dot product is a scalar quantity, which means that its value does not depend on the orientation of the vectors in space.
If we change the reference frame in which the vectors are defined, their coordinates will change, but their magnitude and orientation in space will not. This means that the dot product of the vectors will remain the same, regardless of the choice of frame.
For example, let's say that v1 and v2 have coordinates (a1, b1, c1) and (a2, b2, c2) in a reference frame S. If we change to a different reference frame S', the coordinates of v1 and v2 in this new frame will be (a1', b1', c1') and (a2', b2', c2').
However, using the property v1 * v2 = v1^t v2, where v1^t is the transpose of v1, the dot product can be calculated as:
v1 · v2 = (a1, b1, c1) * (a2, b2, c2) = (a1a2 + b1b2 + c1c2)
This expression shows that the dot product is a scalar that only depends on the scalar product of the vectors' components, and not on the choice of reference frame.
Therefore, we can conclude that the dot product of two free vectors does not depend on the choice of frames in which their coordinates are defined.

Rather than the linear relationship, you might choose to model the upward force on the parachutist as a second-order relationship,
F U =−c’υ 2
Where c’ = a bulk seconds-order drag coefficient (kg/m). (a). Using calculus, obtain the closed-form solution for the case where the jumper is initially at rest (v=0att=0).
(b). Repeat the numerical calculation with the same initial condition and parameter values, but with second-order drag. Use a value of 0.22 kg/m for c’.
(1) The closed-form solution for the case where the parachutist is initially at rest is:
h(t) = h0 + v0t - 0.5gct^2,where h0 is the initial height, v0 is the initial velocity, g is the acceleration due to gravity, and c is the drag coefficient.
(2) When second-order drag is taken into consideration, the equation becomes:
h(t) = h0 + v0t - 0.5gct^2 - 0.5(c'v_0^2/g)t^3,where c' is the bulk second-order drag coefficient. The second-order drag term reduces the height with respect to the case without drag.

K=P*V is a formula for expressing the value of k. The equation might be written as V= k/P if it were turned over.
According to Boyle's law, the proper relationships between volume and pressure are P 1/V and V 1/P. According to Boyle's law, a gas's volume at constant temperature is inversely proportional to its pressure. This means that when a gas's volume grows, its pressure will also decrease since there will be fewer collisions between its molecules and the container's walls. Similar to this, when pressure rises due to higher gas-container wall-to-gas molecule collisions when the gas volume is reduced. The graphic accompanying this answer is the graph illustrating the relationship between an ideal gas's pressure and volume. The regression equation has the form V = kP-1 (which is the same as V = k/P).

A pump B whose characteristics are given in table 1 below is used to pump water from an open tank through 40 m of 70 mm diameter pipe of friction factor f = 0.02 to another open tank in which the surface level of the water is 5.0 m above that in the supply tank. (a) Determine the flow rate when the pump is operated at 1450 rpm. (b) It is desired to increase the flow rate and three (3) possibilities are under investigation. (i) To install a second identical pump in seris with pump B. (ii) To install a second identical pump in parallel with pump B. (iii) To increase the speed of the pump by 10%. Predict the flow rate that would occur in each of these situations.
Answer:
this anawer is much more longer than i expected
Explanation:
a) To determine the flow rate when the pump is operated at 1450 rpm, the following formula can be used:
Q = (π/4) * D^2 * N * v / (60 * f * L), where
D = 70 mm = 0.07 m (diameter),
N = 1450 rpm (speed),
v = fluid velocity,
f = 0.02 (friction factor), and
L = 40 m (pipe length)
Substituting the given values, we get:
Q = (π/4) * 0.07^2 * 1450 * v / (60 * 0.02 * 40)
v = Q / [(π/4) * 0.07^2 * 1450 / (60 * 0.02 * 40)]
We can calculate the head loss due to friction, hf:
hf = f * (L/D) * (v^2 / (2 * g)), where
g = 9.8 m/s^2 (acceleration due to gravity)
Substituting the known values,
hf = 0.02 * (40/0.07) * (v^2 / (2 * 9.8))
v = √[(2 * 9.8 * hf) / (0.02 * (40/0.07))]
The head of water at the pump, h, can be calculated from the difference in water level between the two tanks:
h = 5 m (difference in water level)
The head loss due to the pump, hp, can be calculated using the following formula:
hp = h - hf
Substituting the known values,
hp = 5 - hf
hf = 5 - hp
v = √[(2 * 9.8 * (5 - hp)) / (0.02 * (40/0.07))]
Finally, the flow rate can be calculated:
Q = (π/4) * 0.07^2 * 1450 * v / (60 * 0.02 * 40)
b) (i) If a second identical pump is installed in series with pump B, the head available at the first pump, h1, is equal to the head developed by the second pump, h2. Thus,
h1 = h2
5 - hf1 = hf2
The head loss in each pipe is the same and can be calculated as follows:
hf = f * (L/D) * (v^2 / (2 * g))
Substituting the known values,
hf = 0.02 * (40/0.07) * (v^2 / (2 * 9.8))
The total head loss can be calculated as follows:
hf = hf1 + hf2
Substituting the known values,
hf = hf1 + hf1 = 2 * hf1
v = √[(2 * 9.8 * (5 - hf)) / (0.02 * (40/0.07))]
Q = (π/4) * 0.07^2 * 1450 * v / (60 * 0.02 * 40)
(ii) If a second identical pump is installed in parallel with pump B, the total flow rate will be equal to the sum of the flow rates through each pump. Thus,
Q = Q1 + Q2
Which of the following is the correct statement regarding the inertial reference frame?Select one:a. An inertial reference frame must be fixedb. A reference frame fixed to the earth is not a true inertial reference framec. None of the aboved. An inertial reference frame can move with a non-constant velocitye. An inertial reference frame can have rotations
It is one in which the law of inertia is not applicable. It must be at rest with respect to the Earth: It moves at a steady rate: It is one where Newton's First Law of Motion holds true: AI Recommended Response: The law of inertia does not apply in an inertial frame of reference.
The Sun is the solar system's center of mass and is regarded an inertial frame of reference, except that its speed is slow, as in non-inertial frames, and we can't conduct any experiments to determine its reference frame. Because the Coriolis and centrifugal forces vanish in any inertial frame, the concept of special relativity would identify these frames where the forces vanish as sharing the same and simplest physical laws, and so rule that the spinning frame is not an inertial frame. Assume a body is preserved on the earth's surface; for a person on the earth, it is at rest, however for a person on the moon, it is in motion; which is my inertial frame here? In reality, the phrase inertial frame is relative, which means that we must first assume a reference frame to be the inertial frame of reference. So, a more comprehensive definition of an inertial frame would be: An inertial frame is at rest or moves with constant velocity in relation to my imagined inertial reference frame.

The given signal is periodic with fundamental period, N = 8.
Consider Standard equation,
x(n)=Acos(πn+θ)
Comparing given signal we get,
ωn=0.25πn
2πfn=πn4
∴f=1/8
Result : Given signal, x(n) is periodic with Fundamental Period, N = 4
x(n)=cos(0.5nπ)+sin(0.25nπ)
Solution:
Consider x(n) to be combination of x1(n) & x2(n)
Where,
x1(n)=cos(0.5πn1)& x2(n)=sin(0.25πn2)
∴,ω1n1=0.5πn1 &ω2n2=0.25π [tex]n_{2}[/tex]

Why Would a Pilot Let His Plane Run Out of Fuel?
Numerous issues, including human or technical mistake, might result in running out of fuel.
Here are a few causes of pilots running out of fuel. Flying commercial aircraft involves a lot of unknowns. Each of these has the potential to go wrong and harm the aircraft. The engines won't run if there isn't fuel. The aircraft has to be refueled if its fuel runs out while it is in the air. Otherwise, the aircraft will go down. Unwanted circumstances do arise from time to time, and there are instances of this in aviation history. Despite the fact that each jet's exact answer differs, most of them can fly for at least 60 minutes before needing to refuel. A private jet's range is determined by the size and weight of the aircraft.
