five properties of light
Answer:
Light is electromagnetic radiation that has properties of waves. The electromagnetic spectrum can be divided into several bands based on the wavelength. As we have discussed before, visible light represents a narrow group of wavelengths between about 380 nm and 730 nm.
OR
The primary properties of visible light are intensity, propagation-direction, frequency or wavelength spectrum and polarization, while its speed in a vacuum, 299 792 458 m/s, is one of the fundamental constants of nature.

The magnetic field at point P due to a 2.0-A current flowing in a long, straight, thin wire is 8.0 μT. How far is point P from the wire?
Answer:
r = 0.05 m = 5 cm
Explanation:
Applying ampere's law to the wire, we get:
[tex]B = \frac{\mu_oI}{2\pi r}\\\\r = \frac{\mu_oI}{2\pi B}[/tex]
where,
r = distance of point P from wire = ?
μ₀ = permeability of free space = 4π x 10⁻⁷ N/A²
I = current = 2 A
B = Magnetic Field = 8 μT = 8 x 10⁻⁶ T
Therefore,
[tex]r = \frac{(4\pi\ x\ 10^{-7}\ N/A^2)(2\ A)}{2\pi(8\ x\ 10^{-6}\ T)}\\\\[/tex]
r = 0.05 m = 5 cm

“a car is parked uphill on a sloped street. How would you draw the force diagram to illustrate all of the forces acting on this car to keep it parked on the slope?”
Answer:
Explanation:
There are 3 main forces at work here, gravity, normal and friction. The gravity pulls the car straight down and is what keeps the car on the ground. Normal force is straight up from the points where the car is touching, so since the wheels are the only parts of the car touching the street, this is where all the normal force is. Friction force opposes any and all motion, the car wants to slide down the hill and would slide down the hill if there was no friction, so the friction force is in the opposite direction of the cars intended motion.

about and today's times? If so, how? If not, explain your thoughts?"
Answer:
this is based on your opinion but mine is...
Explanation:
Do you think that the role of culture, gender, and/or race has changed in sclence between the times we are learning about and today's times? If so, how? If not, explain your thoughts?
Yes by how because Race’ cannot be biologically defined due to genetic variation among human individuals and populations. (A) The old concept of the “five races:” African, Asian, European, Native American, and Oceanian. According to this view, variation between the races is large, and thus, the each race is a separate category. Additionally, individual races are thought to have a relatively uniform genetic identity. (B) Actual genetic variation in humans. Human populations do roughly cluster into geographical regions. However, variation between different regions is small, thus blurring the lines between populations. Furthermore, variation within a single region is large, and there is no uniform identity.
Technician A says that daytime running lights (DRLs) light the headlights, usually at reduced intensity, whenever the engine is running. Technician B says high-intensity discharge (HID) headlights are brighter and have a yellow tint. Who is right?
Answer:
technician A is right
Explanation:
Daytime running lights are auxiliary lights that allow other cars to see us better. They are not intended to illuminate the road, so their intensity is low.
Consequently technician A is right
HID lights are high intensity lights, generally bluish-white in color, yellow lights are halogen lights with lower intensity than HID lights.
Consequently, technician B is wrong
Which BEST explains why rainbows only appear when there is rain and sun? a)The rain needs to dim the light for them to appear. b)The combination of light and water creates a prismatic effect. c)The sun restricts the light rays that impact with the water. d) Heavy rain and little sun produce the strongest rainbows.
Answer:
C
Explanation:
Answer:
You're answer would be B.
Explanation:
Fact: A water droplet refracts and disperses the incident sunlight, then reflect it internally and finally refract it again, when it emerges out of water droplet thus acting like a prism.
In Option B, It states: The combination of light and water creates a prismatic
Therefore, This option is true! However, I would say the combination of light and water make more of a chroma effect to water (my opinion)!

10000 J of heat energy is absorbed per cycle by a diesel engine that is 11% efficient. How much energy does it expel to the environment per cycle? (J)
Answer:
8900 J
Explanation:
Let heat absorbed be Q1 and heat rejected be Q2.
Q1 = 1000 J, efficiency η = 11% = 0.11
Then, Efficiency of engine can be found be using the following formula,
[tex]\eta = \frac{Q_1-Q_2}{Q_1}[/tex]
⇒ [tex]0.11 = \frac{10000-Q_2}{10000}\\Q_2 = 10000- 1100= 8900 J[/tex]
Therefore, energy does it expels to the environment per cycle = 8900 J

Oxygen Supply in Submarines Nuclear submarines can stay under water nearly indefinitely because they can produce their own oxygen by electrolysis of water.
How many liters of O2 at 298 K and 1.00 bar are produced in 1.00 hr in an electrolytic cell operating at a current of 0.0200 A?
Answer:
1.865 * 10^-4 L
Explanation:
The equation of the reaction is:
4OH^-(aq) ----->2H2O(l) + O2(g) + 4e
Since one mole of oxygen which occupies 22.4 L is produced in the electrolysis of water by 4 Faraday of electricity as shown in the equation above;
Then;
4 * 96500 C liberates 22.4 L of oxygen
60 * 60 * 0.0200 C will liberate 60 * 60 * 0.0200 * 22.4/4 * 96500
= 1.865 * 10^-4 L
According to Newton's third law, what other force must be happening?
Answer:
The desk is pushing back on Arianna
Explanation:
If you read newton's 3rd law, it states that for every action force (Arianna pushing the desk), there is an equal reaction force (The desk pushing back on her). This is true for EVERY OBJECT THAT HAS MOTION!
Considera los objetos A y B con una masa de 400g cada uno y ambos a una temperatura de 25°C. Si el calor específico de A es mayor que el de B, en las mismas condiciones de calentamiento, ¿Cuál objeto requiere más tiempo para alcanzar una temperatura de 26°C?
Answer:
El objeto A tardará más tiempo para aumentar la temperatura.
Explanation:
Al estar ambos objetos bajo las mismas condiciones de calentamiento, entonces, ambos objetos reciben la misma cantidad de calor por unidad de tiempo.
Si ambas tienen la misma masa y temperatura inicial, pero el objeto A tiene un mayor calor específico, entonces este objeto tardará más tiempo para incrementar su temperatura en 1 °C.

What variables must be known to determine the observed frequency of a wave?
Answer:
The frequency, 'f', of a wave is given by the speed, 'v' of the wave and the wavelength, λ, of the wave
f = v/λ
The frequency, 'f', of a wave is also given by the inverse of the period, 'T', of the wave which is the time it takes the wave to complete an oscillation or a cycle
f 1/T
Therefore, the variables to be known to determine the frequency of a wave includes either, the velocity and the wavelength of the wave or the period of oscillation (the wave cycle) of the wave

The Earth orbits the Sun because of the competing forces of _________________ and _______________________.
The entropy of the substance seems to decrease as this substance freezes. Why is this not contradicting the second law of thermodynamics?
Answer:
See Explanation
Explanation:
While it is true that a version of the second law of thermodynamics stated with respect to entropy states that the entropy of a system only increases or remains the same. It never decreases!
It then appears to be a contradiction when the freezing of ice leads to a more ordered structure and a seeming decrease in entropy of the ice as water changes from liquid to solid.
This law of thermodynamics is not violated here because the entropy of the universe increases (freezing is an exothermic process). This outweighs the decrease in entropy of the system hence the change in entropy is positive and the second law of thermodynamics is not violated.
7. Explain what happens to the volume of a sphere when the radius is tripled?
ANYONE PLS ASAPPPPPPP
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of surface areas and Volumes.
When the radius is 'r', we get as,
V = 4/3*(π)(r^3)
when the radius is tripled that is '3r' , we get as,
V' = 4/3 (π)(3r)^3
V' = 27*(4/3(π)(r^3))
V' = 27 V
hence the new volume, when radius is tripled, is 27 times greater than the old sphere.
