What are polar coordinates?It is two-dimensional coordinate system which uses a straight line distance (from a reference point) and the angle made by it (with respect to reference direction) to represent a point in the X-Y plane.
Given are the position vectors in polar coordinates of three points in X-Y coordinate system.
The transformation from polar coordinates (r, θ) into cartesian coordinates (x, y) is done using the following formulae -
x = r cosθ
y = r sinθ
a) → r = 12.4 m , θ = 170°
x = 12.4 x cos (170°) = 12.4 x -0.98480775301 = -12 .21
y = 12.4 x sin (170°) = 12.4 x 0.17364817766 = 2.15
In cartesian form → ( -12.21 i + 2.15 j )
b) → r = 4 cm , θ = 50°
x = 4 x cos (50°) = 4 x 0.64278760968 = 2.57
y = 4 x sin (170°) = 4 x 0.76604444311 = 3.06
In cartesian form → ( 2.57 i + 3.06 j )
c) → r = 20 inches , θ = 210°
x = 20 x cos (210°) = 20 x -0.86602540378 = -17.32
y = 20 x sin (210°) = 20 x -0.5= -10
In cartesian form → ( -17.32 i - 10 j )
Therefore, in cartesian coordinates, we can write the position vectors as -
a) → r = 12.4 m , θ = 170° ↔ - 12.21 i + 2.15 j
b) → r = 4 cm , θ = 50° ↔ 2.57 i + 3.06 j
c) → r = 20 inches , θ = 210° ↔ - 17.32 i - 10 j

outlet and at the reactor inlet are of 14.4 m s−1 and 10.7 m s−1, respectively. What is the change of rate of kinetic energy (in W )? a. 102.68 b. −698.78 c. −696.53 d. 696.60 e. −102.68
Answers
We find that the change in kinetic energy is positive and equal to 696.60 W, option d. The formula for kinetic energy is given by KE = 1/2 * mv^2, where m is the mass of the fluid and v is its velocity.
In this case, we are given the velocities at the outlet and the reactor inlet, which are 14.4 m/s and 10.7 m/s, respectively. Since the mass of the fluid is not provided, we can assume it to be constant.
The change in kinetic energy is given by the difference in kinetic energies at the outlet and the reactor inlet, which can be calculated using the formula:
ΔKE = (1/2 * m * v_outlet^2) - (1/2 * m * v_inlet^2)
Simplifying this expression, we get:
ΔKE = 1/2 * m * (v_outlet^2 - v_inlet^2)
Plugging in the given values, we have:
ΔKE = 1/2 * m * (14.4^2 - 10.7^2)
Calculating this expression, we find the answer to be approximately 696.60 W. Therefore, the correct option is d. 696.60.
In summary, the change in the rate of kinetic energy is approximately 696.60 W. This is calculated by taking the difference between the kinetic energy at the outlet and the kinetic energy at the reactor inlet using the formula ΔKE = 1/2 * m * (v_outlet^2 - v_inlet^2). Plugging in the given velocities of 14.4 m/s and 10.7 m/s, we find that the change in kinetic energy is positive and equal to 696.60 W.

These charge particles, that travel to the earth from the sun along with electromagnetic radiation, are called the solar wind. The solar wind penetrates the atmosphere of the earth much more at the geopmagnetic north and south poles than anywhere else on the earth. Why
Answers
The solar wind penetrates the Earth's atmosphere much more at the geomagnetic north and south poles due to the configuration of Earth's magnetic field lines.
Earth's magnetic field is generated by its core and creates a protective shield called the magnetosphere. This shield is important because it deflects harmful solar wind particles away from Earth's atmosphere. The magnetic field lines are shaped like loops that extend from the geomagnetic north and south poles. The field lines are more concentrated and closer to the Earth's surface at the poles, which allows solar wind particles to follow these lines and penetrate deeper into the atmosphere at the poles compared to other regions. This increased penetration at the poles is what causes phenomena such as auroras, where charged particles interact with the Earth's atmosphere to create beautiful light displays.

You rev your car's engine to 2500 rpm (rev/min). What is the period of the engine? T = ??s What is the frequency of the engine? f = ??Hz If you change the period of the engine to 0.038 s , how many rpms is it doing? f = ??rpm
Answers
The speed of the car's engine, n = 2500 rev/min. In order to find the period of the engine, we use the formula;T = 1/f, where f = frequency.
Substituting the value of n into the formula, we can write;f = 2500 rev/min = (2500 rev/min) / (60 s/min) = 41.67 rev/s.
Therefore,T = 1/f = 1/41.67 rev/s = 0.024 s.
The period of the engine is 0.024 s.
To find the frequency of the engine; We use the formula f = 1/T.
Substituting the value of T, we get;f = 1/0.024 s = 41.67 Hz.
The frequency of the engine is 41.67 Hz. When T=0.038 s. We can use the formula f = 1/T to find the frequency when T = 0.038 s.
Substituting the value of T, we get;f = 1/T = 1/0.038 s = 26.32 Hz.
Frequency of the engine is 26.32 Hz.
We know that;f = n / 60.
Therefore,n = f × 60.
Substituting the value of f, we get;n = 26.32 Hz × 60 = 1579.3 rev/min.
Therefore, the engine is running at 1579.3 rpm when T = 0.038 s.

At any given time, ____ of the earth is illuminated by the sun. Select one: a. one-fourth b. one-third c. one-half d. two-thirds
Answers
At any given time, one-half of the Earth is illuminated by the sun (sunlight). The correct answer is option c).
This is because the Earth rotates on its axis once every 24 hours, causing different parts of the Earth to be exposed to sunlight at different times. As the Earth rotates, the half facing the sun experiences daytime, while the half facing away from the sun experiences nighttime.
The amount of sunlight that reaches the Earth's surface at any given location also depends on the tilt of the Earth's axis and its orbit around the sun. The Earth's axis is tilted at an angle of approximately 23.5 degrees relative to its orbit around the sun, which causes the seasons.
During the summer solstice, the hemisphere tilted towards the sun receives the most direct sunlight and experiences the longest day of the year, while the opposite hemisphere experiences the shortest day of the year.
During the winter solstice, the opposite occurs. During the equinoxes, the Earth's axis is neither tilted towards nor away from the sun, and both hemispheres experience equal amounts of daylight and darkness.

ben starts waling at 2 mi/h. after an hour and a half amanda begins jogging at 6 mi/h. how long until amanda catches ben
Answers
Amanda would need to catch up to Ben in 6/10 hours, or 0.6 hours.
What is distance?Use the distance equation d = st, which reads distance equals speed times time, to find the distance. Given that both rate and speed denote a specific amount of travel per unit of time, such as miles per hour or kilometers per hour, they are comparable. R = s = d/t indicates that rate r is equal to speed s.
At 7 miles per hour, Amanda starts jogging down the same path.
Thus, following t hours, Amanda's position is determined by:
A(t) = 7t
Ben begins moving at a 2mph pace along a path.
Ben will be at position 2×1.5 = 3 when Amanda departs in an hour and a half. Ben's position therefore after t hours is as follows:
B(t) = 3+2t
A(t) = B(t)
7t = 3+2t
5t = 3
t = 3/5
t = 0.6hrs

If I triple the mass per unit length of guitar string, its natural frequency changes by what factor?
Answers
If you triple the mass per unit length of guitar string, the natural frequency changes by a factor of 0.63.
The natural frequency of a stretched string is given by the formula:
f=\frac{1}{2L}\sqrt{\frac{T}{\mu}}
where f is the frequency, L is the length of the string, $T$ is the tension in the string and \mu is the mass per unit length of the string.
Therefore, if you triple the mass per unit length of the guitar string, then the frequency changes by a factor of: \frac{f_2}{f_1}=\sqrt{\frac{\mu_1}{\mu_2}}
where f_1 is the original frequency and \mu_1 is the original mass per unit length, f_2 is the new frequency and \mu_2 is the new mass per unit length.
Substituting the values, we get:
\frac{f_2}{f_1}=\sqrt{\frac{\mu_1}{3\mu_1}}\frac{f_2}{f_1}=\sqrt{\frac{1}{3}}\frac{f_2}{f_1}=0.63
Therefore, if you triple the mass per unit length of guitar string, its natural frequency changes by a factor of 0.63.

Two point charges are placed at the following points on the x-axis. +2.0 C at
×=0, -3.0.C at 0.40m. Find the electric field strength at 1.20m?
Answers
The electric field strength at a distance of 1.20 m on the x-axis is -1.5 × 10⁴ N/C.
To find the electric field strength at a distance 1.20 m on the x-axis, we can use Coulomb's law:
\($$F=k\frac{q_1q_2}{r^2}$$\)
where F is the force between two charges, q1 and q2 are the magnitudes of the charges, r is the distance between the charges, and k is the Coulomb constant.For a single point charge q located at the origin of the x-axis, the electric field E at a distance r is given by:
\($$E=\frac{kq}{r^2}$$\) where k is the Coulomb constant.
So, let's calculate the electric field due to each charge separately and then add them up:
For the +2.0 C charge at x = 0, the electric field at a distance of 1.20 m is:\($$E_1=\frac{kq_1}{r^2}=\frac{(9\times10^9)(2.0)}{(1.2)^2}N/C$$\)
For the -3.0 C charge at x = 0.40 m, the electric field at a distance of 1.20 m is:
\($$E_2=\frac{kq_2}{r^2}\)
\(=\frac{(9\times10^9)(-3.0)}{(1.20-0.40)^2}N/C$$\)
The negative sign indicates that the direction of the electric field is opposite to that of the positive charge at x = 0.
To find the net electric field, we add the two electric fields\(:$$E_{net}=E_1+E_2$$\)
Substituting the values of E1 and E2:
\($$E_{net}=\frac{(9\times10^9)(2.0)}{(1.2)^2}-\frac{(9\times10^9)(3.0)}{(0.8)^2}N/C$$E\)
net comes out to be -1.5×10⁴ N/C.
Therefore, the electric field strength at a distance of 1.20 m on the x-axis is -1.5 × 10⁴ N/C.

Rearrange to make h the subject and the answer given is 11900 (3sig.fig.)
The maximum height to which he can climb will be 1.168 x 10⁴ meters.
What is potential energy?
The potential energy of a body is the energy of the body due it position. The potential energy always exist for two bodies which are in mutual interaction with each other for example by a force. For body a on earth, the potential energy of the body - earth system is -
E[P] = mgh
Given is a mountain climber that has a mass of 95 kg.
We can write -
Mass of climber = [M] = 95 kg
Energy gained by eating the chocolate = [E] = 11.1 MJ = 1.11 x 10⁷ joules
Assume that the height achieved achieve by the climber is [h] meters
Therefore, the potential energy gained at that height will be equal to 11 MJ
Therefore -
mgh = 1.11 x 10⁷
95 x 10 x h = 1.11 x 10⁷
95 x 10 x h = 1110 x 10⁴
h = (1110 x 10⁴)/950
h = 1.168 x 10⁴ meters
