A wave with a period of three seconds travels at a speed of 12 m/s what is the wavelength of the wave

Answer:

<em>λ </em>= 0.28m

Explanation:

Equation used is <em>v = λf</em>, where <em>v</em> is velocity, <em>λ</em> is wavelength, and <em>f</em> is frequency

We need to find wavelength so rearrange the equation in term of wavelength.

<em>v = λf</em>

<em>λ = f/v</em>

We know that period is the inverse of frequency (f = 1/T), so lets substitute that into our equation

<em>λ = f/v</em>

<em>λ = (1/T)/v</em>

Plug in your the given values given in the question.

We're given v=12m/s and T=3sec

<em>λ = (1/T)/v</em>

<em>λ</em> = (1/3)/12

<em>λ</em> = 1/36 = 0.2777777 = 0.28m

If a substance is found to be reactive flammable soluble and explosive what observation is also a physical property
Ainat [17]

Answer:

  • <u><em>soluble</em></u>

Explanation:

Chemical properties only manifest when a chemical reaction occurs. Being reactive, flammable and explosive are chemical properties, because they involve chemical reactions: the substances are changed; the chemical bonds of some substances, called reactants, are broken, and the chemical bonds are created, forming other substances, called products.

Solubility is a<em> physical property</em> because during dissolution no new substances are formed. You can prove it when the solvent evaporates leaving behind the same original substance.

The the observation that the substance is <em>soluble</em> is describing a <em>physical property.</em>

What is the oxidation number of the element Se
maria [59]

Answer:

The oxidation number of a monatomic (composed of one atom) ion is the same as the charge of the ion. For example, the oxidation numbers of K+, Se2−, and Au3+ are +1, -2, and +3, respectively. The oxidation number of oxygen in most compounds is −2.

One cycle of the power dissipated by a resistor ( R = 800 Ω R=800 Ω) is given by P ( t ) = 60 W , 0 ≤ t &lt; 5.0 s P(t)=60 W, 0≤
OLga [1]

Answer:

42.5W

Explanation:

To solve this problem we must go back to the calculations of a weighted average based on the time elapsed thus,

Power_{avg} = \frac{P_1(t_1)+P_2(t_2)}{t_1+t_2}

We need to calculate the average power dissipated by the 800\Omega resistor.

Our values are given by:

P(t)=60 W, 0\leq t

P(t)=25 W, 5.0\leq t

Aplying the values to the equation we have:

Power_{avg} = \frac{P_1(t_1)+P_2(t_2)}{t_1+t_2}

Power_{avg} = \frac{60(5-0)+25(10-5)}{(5-0)+(10-5)}

Power_{avg} = 42.5W
