Answer:

The wavelength of the waves created in the swimming pool is 0.4 m

Explanation:

Given;

frequency of the wave, f = 2 Hz

velocity of the wave, v = 0.8 m/s

The wavelength of the wave is given by;

λ = v / f

where;

λ is the wavelength

f is the frequency

v is the wavelength

λ = 0.8 / 2

λ = 0.4 m

Therefore, the wavelength of the waves created in the swimming pool is 0.4 m

A cell phone charger operates at 5 volts and can deliver a maximum current of 1.0 Amp. If your cell phone has an energy storage
madam [21]

Answer:

<em>it</em><em> </em><em>takes</em><em> </em><em>2</em><em>.</em><em>1</em><em>6</em><em> </em><em>hrs</em><em> </em><em>to</em><em> </em><em>fully</em><em> </em><em>charge</em><em> </em><em>the</em><em> </em><em>phone</em>

Explanation:

V = 5v

I = 1A

E = 38.9 Kj = 38900 j

t = ?

E = IVt

t = E/IV

t = 38900 ÷ (1 × 5)

t = 38900 ÷ 5

t = 7780 seconds

t = 7780/3600............( converting time in seconds to hours)

t = 2.16 hrs

A sled of mass m is coasting on the icy surface of a frozen river. While it is passing under a bridge, a package of equal mass m
sweet [91]

Answer:B

Explanation:

Given

mass of Sled is m

another package of mass m is thrown on it

Suppose u be the initial velocity of sled

conserving momentum

mu=2mv

v=\frac{u}{2}

where v is the final velocity

Initial kinetic energy =\frac{1}{2}mu^2

Final Kinetic Energy=\frac{1}{2}(2m)\cdot (\frac{u}{2})^2

Final Kinetic Energy=\frac{1}{2}\times \frac{1}{2}mu^2

Final kinetic Energy is half of initial

Acetic acid (HC2H3O2) is an important ingredient of vinegar. A sample of 50.0 mL of a commercial vinegar is titrated against a 1
butalik [34]

Answer:

The concentration of acetic acid present in the vinegar is 0.113M

Explanation:

1. As the titration occurs between an acid and a base is called neutralization. The balanced chemical reaction between the acetic acid and the NaOH is:

NaOH+HC_{2}H_{3}O_{2}=NaC_{2}H_{3}O_{2}+H_{2}O

2. Calculate the moles of NaOH used, taking in account the concentration of NaOH 1.00M:

5.65mL*\frac{1.00molesNaOH}{1000mLNaOH}=0.00565molesNaOH

3. Calculate the number of moles of acetic acid neutralized using stoichiometry:

0.00565molesNaOH*\frac{1molHC_{2}H_{3}O_{2}}{1molNaOH}=0.00565molesHC_{2}H_{3}O_{2}

4. Calculate the concentration of acetic acid present in the vinegar:

\frac{0.00565molesHC_{2}H_{3}O_{2}}{50.0mLvinegar}*\frac{1000mLvinegar}{1Lvinegar}=0.113M
