Explanation:
Dos resistencias de 30 y 20 Ω se conectan en seria a un generador que tiene una diferencia de potencial de 20 V entre sus bornes. a. Determina la resistencia equivalente de la asociación b. Dibuja el circuito y coloca un amperímetro que indique el valor de la intensidad de la corriente y unos voltímetros que muestren la diferencia de potencial entre los extremos de las resistencias ¿Qué valores muestran estos aparatos?
Answer:
V = 12V, V = 8V
Explanation:
a) In this series circuit the equivalent resistance is
Req - R1 + R2
Req = 30 + 20
Eeq = 50 Ω
b) see attached
c) the circuit current is
i = V / Req
i = 20/50
i = 0.4 A
voltages are>
V = 0.4 30
V = 12V
V = 0.4 20
V = 8V

Use this free body diagram to help you find the magnitude of the force needed to keep this block in static equilibrium.
А.15.3 newtons
В.36.3 newtons
C. .63.5 newtons
D. 95.5 newtons
Split F₁ into its horizontal and vertical components:
F₁ = F₁ cos(θ) i + F₁ sin(θ) j
(boldface = vector; regular font = magnitude)
By Newton's second law, if the object is in equilibrium, then
• the net horizontal force on the block is
∑ F = F₁ cos(θ) - F₃ = 0 → F₁ cos(θ) = 70 N
• the net vertical force is
∑ F = F₁ sin(θ) + F₂ - W = 0 → F₁ sin(θ) = 65 N
Recall that cos²(θ) + sin²(θ) = 1 for any θ, so we have
(F₁ cos(θ))² + (F₁ sin(θ))² = (70 N)² + (65 N)²
F₁² = 9125 N²
F₁ = √(9125 N²) ≈ 95.5 N
All objects in our solar system orbit the Sun. How is the movement of planets like
Earth around the Sun different than that of comets traveling around the Sun?
PLEASE HELP I WILL GIVE BRAINLIEST JUST PLEASE PLEASE HELP
Answer:
planets move in elliptical orbit.
Explanation:
this is because planets are formed closer to the sun while the comets are formed further.
The Sun is home to 99.85% of all stuff in the Solar System.All objects in our solar system orbit the Sun.The movement of planets is elliptical in nature.
What is solar system?Our solar system consists of the Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, as well as the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
It consists of the planets' satellites, as well as numerous comets, asteroids, and meteoroids, as well as the interplanetary medium. The Sun is home to 99.85% of all stuff in the Solar System.
The movement of planets is elliptical due to the fact that planets are present closer to the sun while the comets are present farther away from the sun as compared to the planets.
Hence the movement of planets is elliptical in nature.

The local newspaper has published the passage below. Last week, scientists released incredible images of aurora australis, known as the northern lights, as seen from the Hubble telescope. The Hubble telescope was placed in orbit in 1990 by the space shuttle and has since delivered the sharpest images we have of our planet, our galaxy, and the universe. The images delivered last week show the beautiful display of lights in the southern hemisphere. These lights are the result of the solar activity known as solar wind. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn. Which statement in the news passage above is inaccurate
Answer:
The statement as aurora australis known as northern lights is incorrect. As the designation of aurora australis is for the southern lights i.e. which occur in the southern hemisphere.
Explanation:
Aurora or natural lights is a phenomenon that occurs at the poles of the Earth due to interaction between the Earth's magnetic field and cosmic rays. This interaction results in the beautiful display of colors on both poles. These are named, aurora borealis or aurora australis depending on their geographical location. If they occur on the northern pole they are termed as aurora borealis while those occurring on the southern pole are named aurora australis.
Answer:
C. The aurora australis is known as the northern lights.

A cruise ship travels across a river at 25 meters per minute. If the river is 6200 meters wide, how long
does it take the ship to reach the other side.
Answer:
248 minutes
Explanation:
6200/25=248
This means there is 248 25s in 6200
which means it will take 248 minutes to travel through the river
Also here's a neat trick:
The units for speed is meters/minute
The units for distance is meters
Dividing distance by speed will cancel out the meters and leave only the speed.

find the energy released when there is a decrease of 0.3kg of material in a nuclear reaction
Answer:
E = 2.7 x 10¹⁶ J
Explanation:
The release of energy associated with the mass can be calculated by Einstein's mass-energy relation, as follows:
[tex]E = mc^2[/tex]
where,
E = Energy Released = ?
m = mass of material reduced = 0.3 kg
c = speed of light = 3 x 10⁸ m/s
Therefore,
[tex]E = (0.3\ kg)(3\ x\ 10^8\ m/s)^2[/tex]
E = 2.7 x 10¹⁶ J
The distance between the two nearest points on a wave where the particles are in phase is 2 m. What is the wavelength of the wave?
A. 1/2 m
B. 1 m
C. 2 m
D. 2 seconds
E. none of these
Answer:
Suppose that the wave equation is:
f(x) = A*cos(k*x)
The wave is in phase for two points x₁ and x₂ if:
f(x₁) = f(x₂)
And if these points are consecutive (for example, two consecutive peaks) then the wavelength of the wave is:
wavelength = x₂ - x₁
In this case, we know that the wave is in phase for two points that are 2 m apart.
Then we can use the points:
x₁ and x₂ such that:
x₂ = x₁ + 2m
We also know that these are the nearest points such that this happens, then we can assume that the points are consecutive.
Then the wavelength will be:
wavelength = x₂ - x₁ = (x₁ + 2m) - (x₁) = 2m
Then the wavelength is 2m.
The correct option is C.

Determine whether the interference is constructive or destructive at each location indicated.
A.constructive or destructive
B. constructive or destructive
C. constructive or destructive
D. constructive or destructive
Answer:
A. Constructive
B. Destructive
C. Destructive
D. Constructive
Explanation:
Constructive interference takes place at locations along the path of two superposed waves where the waves are in phase such that a high or low point of one of the waves corresponds with a high or low point of the other wave which gives a resulting wave amplitude which is the sum of the amplitudes of the individual waves
Destructive interference takes place at locations along the path of two superposed waves where one wave is out of phase with the other wave such that a high or low point of one of the waves coincides with a low or high point of the other wave respectively thereby cancelling the effect of the other wave and giving a resulting wave that has an amplitude which is the difference in the amplitudes of the individual waves
Therefore;
At point A, the peak of each wave partially coincides resulting in constructive interference
At point B, the peak of the blue wave and the trough of the red wave partially coincides resulting in destructive interference
At point C, the through of the blue wave and the peak of the back wave partially coincides resulting in destructive interference
At point D, the trough of each wave partially coincides resulting in constructive interference.
Write your question here (Keep it simple and clear to get the best answer) a car accelerates uniformly from an initial velocity of 10m/s at 2m/s squre for 4s.What is the average velocity
Answer:
Average velocity = 18 m/s
Explanation:
Given the following data;
Initial velocity = 10m/s
Acceleration = 2m/s²
Time = 4 seconds
To find the average velocity, we would use the first equation of motion;
[tex] V = U + at[/tex]
Where;
V is the final velocity.
U is the initial velocity.
a is the acceleration.
t is the time measured in seconds.
Substituting into the equation, we have;
V = u + at
V = 10 + 2*4
V = 10 + 8
V = 18 m/s
An object travels a distance d with acceleration a over a period of time t according to the equation: d = at² After 2.3 seconds with an acceleration of 9.8 m/s2, how far does an object travel (rounding the answer to two significant figures)?
Answer:
A 26m
Explanation:
firstly the answer will not be part c as distance unit will be meters (m)
next, substitute the values of a and t as shown
[tex]\frac{1}{2} (9.8)(2.3)^2 = 25.921[/tex]
the answer rounded off to 2 significant figures will be hence 26m
