Answer:

The true statement is that sound travels through solids easier than liquids

Explanation:

The first statement is wrong as sound travels faster within a denser medium

The third statement is wrong as sound travels faster within a denser medium

The fourth statement is wrong as solids are denser than liquids. That is why when you put your ear on the track of a train (DON'T TRY IT) the sound reaches faster to your ears than if you hear something underwater

Answer:

Sound travels through solids and liquids at the same speed

Explanation:

Because sound needs a dencer object to travel fast and since both liquid and solids are closer than gas sound travles faster in them.

The peak magnetic field of the electromagnetic wave in the red part of the visible spectrum is 9.67 x 10⁻¹⁰ T.

<h3>Relationship between electric and magnetic field</h3>

The relationship between electric and magnetic field at a given peak electric field is given as;

c = (E₀) / (B₀)

where;

  • c is speed of light
  • E₀ is the peak electric field
  • B₀ is the peak magnetic field

B₀ = E₀ / c

B₀ = (2.9) / (3 x 10⁹)

B₀ = 9.67 x 10⁻¹⁰ T

Thus, the peak magnetic field of the electromagnetic wave in the red part of the visible spectrum is 9.67 x 10⁻¹⁰ T.

Solve the equation x=3logy2 for y.
melisa1 [442]

X = 3 · log(Y²)

X = 3 · 2·log(Y)

X/6 = log(Y)

10^(X/6) = 10^log(Y)

Y = 10^(X/6)

An object of mass 800g hangs on a spring. Calculate the force exerted by the object if acceleration due to gravity is 10/s2​
xxTIMURxx [149]

Answer:

8 N

Explanation:

Using the equation F=ma (F: force/ m: mass  in kg/ a: acceleration),

F = (800/1000)(10)

F = 8 N
