how is light reflected from a prism
Answer:
White light entering a prism is bent, or refracted, and the light separates into its constituent wavelengths. Each wavelength of light has a different colour and bends at a different angle. The colours of white light always emerge through a prism in the same order—red, orange, yellow, green, blue, indigo, and violet.
What do you know about nuclear energy?
Answer:
Nuclear energy comes from splitting atoms in a reactor to heat water into steam, turn a turbine and generate electricity. Ninety-three nuclear reactors in 28 states generate nearly 20 percent of the nation's electricity, all without carbon emissions because reactors use uranium, not fossil fuels.

Describe how you would measure the Volume of an irregular solid object.
You can include any apparatus and equations.
Answer:
Find a recipient that you can put the object completely inside, and fill this recipient with water. After, you put the irregular solid you want to measure the volume inside, and the water will spill out the recipient. So you take the water that spilled out and uses a graduated recipient to measure the volume of water. The volume of the solid will be exactly the same volume of water that spilled of the first recipient
The P.E stored by a mass spring system at an extension of 2 cm is 10 J. The P.E stored by the same system at an
extension of 4 cm will be:
Explanation:
extension(x) = 0.02m When the P.E is 10J.
extension(x)= 0.04m PE?.
P.E is proportional to Extension²
P.E/x² = P.E"/x"²
10/(0.02)² = P.E/(0.04)²
P.E= 10x(0.04)²/(0.02)²
P.E= 40J
6. 498.82 mg comverted to kg
Answer:
0.00049882 kg
........................
Answer:
498.82 mg=0.00049882 kg
Explanation:
To get this answer, you must multiply the quantity of mg by 0.000001, which is also 0.001². Since one gram is 1000 mg, and 1000 g is 1 kg, you must divide the amount of mg by one million, or multiply by 1/1000000, or 0.000001. I hope this helped you. Enjoy your day, and take care!

39 liters of water at
20 °C are mixed with
21 liters of water at
60 °C. What is the
temperature of the
mixture?
Answer:
Temperature of the mixture=8 °C
Explanation:
Let, Temperature of the mixture=t °C
Q₁ = Q₂
=> m₁SΔΘ₁ = m₂SΔΘ₂
=> 39 × (20+t) = 21 × (60-t)
∴ t = 8 °C

If Bert the Bat travels eastward at 40 mph with a tailwind of 6 mph, what is his actual speed?
Answer:
36 mph.
Explanation:
Now Albert here is using the wind to his advantage but if say there was no wind then he would not have the 6 mph behind him so we subtract 6 from 40 to get 36. hope this helps :)

in the Newton's Third Law of Motion state three characteristics
Answer:
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.

A student uses the right-hand rule as shown.
What is the direction of the magnetic field in front of the wire closest to the student?
O up
Oright
O down
O left
Answer: O:right
Explanation: In this case you place your finger on the current, and your fingers should curl showing the way, you must use your right hand in this case, otherwise that would mean the fingers on your left would bend way back, and snap off, (Not really lol, just saying)
The direction of the magnetic field in front of the wire closest to the student is right. Thus, the correct option is B.
The direction of the magnetic field encircling a current-carrying wire can be determined using the right-hand rule. The magnetic field's direction is shown by the direction in which your fingers wrap around the wire if you point your right thumb in the direction of the current.
In this case, the student is using the right-hand rule with their thumb pointing upward. This means that the direction of the current is flowing into the page, perpendicular to the direction of their thumb.
To determine the direction of the magnetic field in front of the wire closest to the student, we can curl our fingers around the wire in the direction of the current (into the page) while keeping our thumb pointing upward. This results in the direction of the magnetic field being to the student's right.

A baseball diamond is a square (don’t be fooled that it is usually shown rotated by 45°). Each side of the square is 90 feet long (to two significant figures). How far must a fielder throw the ball from second base to home plate?
A line from second to home creates a right triangle with 45 degree angles.
This makes the diagonal line the side length of the square multiplied by the sqrt(2)
Second to home = 90sqrt(2) = 127.279 feet ( round answer as needed)
the length of air column at which the first resonance was observed when a vibrating fork was placed on a resonance tube was 30cm. Calculate the wavelength of air column and frequency of the fork speed of sound 330m/s
[tex]\boxed{\sf Wavelength=\lambda=4\ell}[/tex]
[tex]\\ \sf\longmapsto \lambda=4(0.3)[/tex]
[tex]\\ \sf\longmapsto \lambda=1.2m[/tex]
Now
[tex]\boxed{\sf Frequency=\nu =\dfrac{v}{\lambda}}[/tex]
[tex]\\ \sf\longmapsto \nu=\dfrac{330m/s}{1.2m}[/tex]
[tex]\\ \sf\longmapsto \nu=275s^{-1}[/tex]
Answer:
Velocity=330m/s=v
Length=l=30cm=0.3m
Wavelength=λ=4ℓ
⟼λ=4(0.3)
⟼λ=1.2m
Now
Frequency= ν= λ/v
⟼ν= 1.2m/330m/s
⟼ν=275s^-1
