Answer:
B. They reproduce
Explanation:
Both arent made up of one cell, and both arent made up of mutliple cells. Only some unicellular and multicellular organisms are infectious.
Answer:
Your answer would be:
B.) They reproduce.
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism. Multicellular organisms use many different cells to function.

How are stationary waves formed on a string?
Answer:
hey, please open my account and see my question, please help me solve the task, I have to send it to the teacher soon.
Answer:
When waves are generated and they reflect off a fixed end, the reflected waves are completely out of phase. The reflected waves and the incident waves interfere with each other along the path and results in the formation of nodes and anti-nodes. Nodes are points of completely out of phase interference and anti-nodes are points of completely in phase interference.
-What is the potential energy at point A?
-What is the kinetic energy at point A?
-What is the kinetic energy at point B?
-What is the potential energy at point D?
-What is the kinetic energy at point D?
Answer:
1560520156Explanation:
Assuming there is no friction or other force involved, recall that energy is conserved in a system as long as no external force acts on the system.
Using the data from point C, we can find out that the total energy of the system is 156 because [tex]E = K+Pe[/tex].
Since at point A the object doesn't move, it has Kinetic energy of 0, because [tex]K=\frac{1}{2} mv^2[/tex], therefore [tex]0=\frac{1}{2} m0^2[/tex]. However at point A it has maximum Potential energy, because [tex]Pe=mgh[/tex].
At point B, we can find the Kinetic energy by using [tex]E = K+Pe[/tex]. Substitute values:
[tex]156=104+K\\52=K[/tex]
At point D, the object has maximum kinetic energy and no potential energy, therefore it's the opposite of point A.

Problem 19: Oil with a density of 892 kg/m is flowing smoothly through a pipe, as
shown. In the lower portion, the oil is flowing at vi = 1.84 m/s, and the pressure gauge
indicates P, = 237 kPa. In the upper portion of the pipe, oil is flowing at V2 = 3.61 m/s at a
height that is 8.63 m above the lower portion.
The pressure of the oil with the given properties flowing in the horizontal pipe at the upper portion of the pipe is 157 kPa.
Pressure in the upper portion of the pipe
The pressure in the upper portion of the pipe is calculated by applying Bernoulli's equation,
P₁ + ¹/₂ρv₁² + ρgh₁ = P₂ + ¹/₂ρv₂² + ρgh₂
Given;
P₁ = 237 kPav₁ = 1.84 m/sh₁ = 0v₂ = 3.61 m/sh₂ = 8.63 mρ = 892 kg/m³P₂ = ?Susbtsitute the given parameters and solve the for the pressure in the upper portion of the pipe.
237,000 + ¹/₂(892)(1.84)² + (892)(9.8)(0) = P₂ + ¹/₂(892)(3.61)² + (892)(9.8)(8.63)
238,509.9776 = P₂ + 81,252.325
P₂ = 238,509.9776 - 81,252.325
P₂ = 157,257.65 Pa
P₂ ≅ 157 kPa
Thus, the pressure of the oil with the given properties flowing in the horizontal pipe at the upper portion of the pipe is 157 kPa.

What role does your chosen reaction play in your life? Combustion
Answer:
When fuels burn in combustion reactions, they release useful thermal energy (heat). Combustion reactions are used to heat our homes, power most cars, and to generate a lot of our electricity.
Energy production from the reaction is what drives life and human greed. We stay alive by eating carbon-rich compounds, which are then burned in a spectacularly controlled and efficient manner to provide us with energy. It is the all-important energy term in the combustion equation that has made life on Earth possible

Calculate the electric field at x = 2 given the electric potential at this point is ϕ=3x3.
Hi there!
Recall the following relationship:
[tex]E = -\frac{dV}{dx}[/tex]
E = Electric field strength (V/m)
V = Potential Difference (V)
Take the derivative of the given electric potential equation using the power rule:
[tex]\frac{d}{dx}x^n = nx^{n-1}[/tex]
[tex]-\frac{dV}{dx} = -(3 \cdot 3 \cdot x^2) = -9x^2[/tex]
Evaluate at x = 2:
[tex]E(2) = -9(2^2) = \boxed{-36 \frac{V}{m}}[/tex]
**The magnitude of the field strength would simply be 36 V/m.

2. how does the sound change when you increase the frequency of the waveform?
3. how does the waveform change when you decrease the frequency?
4. how does the sound change when you decrease the frequency?
pls help
Answer:
1.Wave frequency is the number of waves that pass a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.
What is the magnetic flux going through a coil with 0.065 m2 area if the intensity of the magnetic field is 0.114 T.
Hi there!
[tex]\Phi _B = \int B \cdot dA[/tex]
φ = Magnetic Flux (Wb or Tm²)
B = Magnetic field strength (T)
A = Area (m²)
This equation includes a dot product, so this can be rewritten as:
[tex]\Phi _B = B A cos\theta[/tex]
In this instance, the field is parallel to the area, so cos(0) = 1.
Calculate the magnetic flux by plugging in the given values.
[tex]\Phi _B = BA = 0.114 * 0.065 = \boxed{0.00741 Wb}[/tex]

A charged particle moves in a uniform magnetic field of 0.775 T
with a period of 4.79×10−6 s.
Find its charge-to-mass ratio ||/.
Hi there!
Recall that a charge that enters a magnetic field while moving experiences a magnetic force that causes it to enter a state of uniform circular motion.
We know the following (For a point charge):
[tex]F_B = qv B[/tex]
q = Charge (C)
v = velocity (m/s)
B = Magnetic field (T)
Fb= Magnetic force (N)
The equation for centripetal force:
[tex]F_c = \frac{mv^2}{r}[/tex]
m = mass (kg)
v = velocity (m/s)
r = radius (m)
Fc = Centripetal force (N)
Since we are given its period:
[tex]T = \frac{2\pi r}{v}\\\\v = \frac{2\pi r}{T}[/tex]
Plug this expression into the above equations. Since the magnetic force equals the centripetal force, set them equal to each other and simplify.
[tex]q\frac{2\pi r}{T} B = \frac{m}{r}(\frac{2\pi r}{T})^2[/tex]
Cancel out the expression.
[tex]qB = \frac{m}{r} (\frac{2\pi r}{T})[/tex]
Cancel out 'r'.
[tex]qB = \frac{2\pi m}{T}[/tex]
Now, we can simplify as necessary to find a value for 'q' over 'm':
[tex]\frac{q}{m} = \frac{2\pi }{TB} = \frac{2\pi }{(4.79 \times 10^{-6})(0.775)} = \boxed{1692554.464}[/tex]
Thus, the charge is 1.693 ×10⁶ times larger than its mass.

An audio compact disk (CD) has a playing time of 55 minutes. When the music starts, the CD is
rotating at an angular speed of 480 revolutions per minute (rpm) and during the playback the
rotation slows down. The average angular acceleration of the CD is a = -4.0 rev/min . Find the
angular speed at which the CD is rotating at the end of the music. Express your answer both in
rev/min and also in rad/s.
Select one:
27.2 rad/s
220 rad/s
120 rad/s
260 rad/s
22 rad/s
Answer:
See below
Explanation:
-4 rev / min^2 * 55 min = - 220 rev/ min
480 - 220 = 260 rev/min at end
2pi radians /rev * 260 rev/min = 1633.6 Radians/min
At the end of the music, the angular speed of the C.D. would be (d) 260 rev/minute and 1633.6 rad/minute
To calculate angular speed following information is given in the question:
The angular speed (ω) of the C.D. at starting = 480 revolutions/minuteThe playing time (t) of the C.D. is = 55 minutesThe angular acceleration (α) of the C.D. = -4 rev/[tex]min^{-2}[/tex] Angular speed of the C.D. at the end of the music will be = α*tAngular speed of the C.D. at the end of the music will be = 4 rev/[tex]min^{-2}[/tex] *55 min = -220 rev/minAt the end of the music angular speed = 480-220 rev/min = 260 rev/minValue of angular speed in rad/sec = 2π radians/rev*260 rev/min = 1633.6 Radians/minHence, option (d) is correct which states that the angular speed is 260 rev/min and 1633.6 radians/min.
