I don’t know what to put in the boxes below

Answer:

Running is faster, uses more kilojoules and demands more effort from the heart, lungs and muscles than jogging. Running requires a higher level of overall fitness than jogging. Both running and jogging are forms of aerobic exercise.

Explanation:

[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

hope it's help you...!!!!

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

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.

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

The gravitational force is a force that attracts any two objects with mass. Two major factors, mass and distance, affect the strength of gravitational force on an object.Newtons kg-2 m2 is it's SI unit.

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 :)

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.

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.

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!

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)

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

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.

Explanation:
