Two 10.-ohm resistors have an equivalent resistance of 5.0 ohms when connected in an electric circuit with a source of potential difference. Using circuit symbols found below, draw a diagram of this
circuit.
Answers
The resistors are connected in parallel between the terminals of a battery.
Note: If those resistors are connected in parallel, then their equivalent resistance is already 5 ohms, even if they're still in the drawer or in a box on the shelf. They don't have to be connected to a source of voltage for that to happen.

Answers
Answer:
680.4
Explanation:
the formula is V1 over T1 is equals (=) to V2 over T2 .
and we have been given that
V1 represents 315
T1 represents 25°c
V2 is unknown and what we're finding
T2 represents 54°c
so 315×54 all over 25 ...gives you 680.4

D. Neap tides, which is where there are very high tides and very low tides
Answers
Answer:
The answer is B. Spring tides, which are where there are very high tides and very low tides.
Explanation:
Spring tides occur when the sun and the moon are in alignment with Earth.
At the time of a new moon or full moon when the sun, earth, and the moon are in full alignment the solar tide affects the lunar tide leading to the creation of extra-high high tides, and very low, low tides. The basic reasons for this phenomenon are the gravity of the sun and the moon is acting on the earth oceanPlease thank my answer and vote. (Maybe mark brainliest please)

Answer:
I = 1.8 N s, it is directed towards the right
Explanation:
For this exercise we use the relationship between momentum and moment
I = Δp
F t = p_f - p₀
in this case the initial velocity is v₀ = - 2,0 m / s and final velocity v_f = 10,0 m / s, we assume the positive right direction
I = m (v_f - v₀)
let's calculate
I = 0.150 (10.0 - (-2.0))
I = 0.150 (10 + 2)
I = 1.8 N s
as the impulse is positive it is directed towards the right

What is refraction?
It is the phenomenon of bending of light when it travels from one medium to another medium. The bending towards or away from the normal depends upon the medium of travel as well as the refractive index of the material.
Snell's law,
n₁sin(θ₁) = n₂sin(θ₂)
Where n is the refractive index and θ represents angles
A concave lens is used to diverge the incident rays of light falling on it. because of this, the image formed by the concave lens is virtual.
These concave lenses are used in several days to day life applications such as cameras, telescopes, and eye glasses.

Your Answer:
Answer
units
Answers
Answer:
η = 0.7
Explanation:
The refractive index of the material can be calculated by using the following formula:
[tex]\eta = \frac{c}{v}\\[/tex]
where,
η = refractive index of the material = ?
c = speedof light in vaccuum = 3 x 10⁸ m/s
v = speed of light in this material = 4.3 x 10⁸ m/s
Therefore,
[tex]\eta = \frac{3\ x\ 10^8\ m/s}{4.3\ x\ 10^8\ m/s}[/tex]
η = 0.7

The largest Brazilian rainforest is the Amazon rainforest, which is the largest rainforest in the world and occupies 42% of the Brazilian territory. The forest is composed of a rich environmental diversity, constituted by many species of fauna and flora and diverse river resources.
However, there is a growing transformation in the Amazon rainforest caused by organizational exploitation that uses its resources to transform the forest area into agricultural land and pastures for livestock. This problem will cause a reduction in sustainability over time, which will cause serious negative effects on the environment, such as a reduction in biodiversity and an increase in the emission of gases responsible for the greenhouse effect on the planet.

When an ionic compound dissolves like salt, what breaks apart from each other in the water?
Answers
Answer:
When ionic compounds dissolve in water, they break apart into the ions that make them up through a process called dissociation. When placed in water, the ions are attracted to the water molecules, each of which carries a polar charge. ... The ionic solution turns into an electrolyte, meaning it can conduct electricity.
The bonds that is present between atoms of ionic compounds break apart when it is dissolved in water.
What happen when ionic compound dissolve in water?When ionic compounds dissolve in water, the ions in the solid separate in the solution because water molecules has polar nature which attracts that ions. The hydrogen of water molecule attracts chlorine of ionic compound whereas hydroxle ion attracts sodium of ionic compound.
So we can conclude that the bonds that is present between atoms of ionic compounds break apart when it is dissolved in water.

In which of these can convection not occur
A. Gases
B.solids
C.liquids
D.fluids
Answers
I believe the answer would be B.solids.
Explanation:
Hope this helped!
In solids these can convection not occur and convection can occur in both liquids and gases, as they are both considered fluids. Thus, option B is correct.
However, convection cannot occur in solids, as the particles in solids are generally fixed in position and do not have the freedom to move and transfer heat through bulk motion as in convection.
A solid is one of the three fundamental states of matter, along with liquids and gases. It is characterized by having a definite shape and volume. Solids are composed of tightly packed particles, such as atoms, molecules, or ions, that are held together by strong intermolecular forces.
These particles vibrate in fixed positions but do not have the ability to move freely throughout the substance. As a result, solids maintain their shape and volume under normal conditions and exhibit relatively low compressibility compared to gases and liquids. Examples of solids include metals, rocks, wood, plastics, and ice.

A skateboarder traveling at 7.0 meters per second rolls to a stop at the top of a ramp in 3.0 seconds. What is the skateboarder’s acceleration?
*Please only answer if you know - and ABSOLUTLEY NOOOOOOOO LINKS*
Thank you! :)
Answers
Answer:
-2.33 m/s²
Explanation:
The computation of the skateboarder’s acceleration is shown below;
Acceleration means the change in velocity per unit with respect to time.
In the given case, the initial velocity is 7 m/s.
As in the question it is mentioned that it comes to a stop, so the final velocity would be zero.
And, The time elapsed is 3 seconds.
Now the following equation should be used
a = (v,final - v,initial) ÷ t
= (0 - 7)/3
= -2.33 m/s²
