If the amplitude of ocean waves increases by a factor of 1.1, by how much does the energy increase?

Chemistry

klasskru [66]3 years ago
6 0

Answer:

The energy increases by a factor of 1.2.

Explanation:

The energy (<em>E</em>) of an ocean wave is directly proportional to the square of its amplitude (<em>A</em>).

<em>E</em> ∝ <em>A</em>² or <em>E = kA</em>²

If you have two waves with amplitudes <em>A</em>₁ and <em>A</em>₂, then

\frac{E_{2} }{E_{1} } = \frac{A_{2}^{2} }{A_{1}^{2} } = (\frac{A_{2} }{A_{1} }})^{2}

If <em>A</em>₂ = 1.1<em>A</em>₁, then

E_{2} = E_{1} \times (\frac{1.1A_{1} }{A_{1} })^{2} = (1.1)^{2} = 1.2

The energy increases by a factor of 1.2.

A sample of methane (CH4) has a volume of 25 mL at a pressure of 0.80 atm. What is the volume of the gas at each of the followin
Xelga [282]

Answer:

a. 50ml b.10ml c. 6.097ml d. 190.1 ml

Explanation:

According to Boyle's law

Volume is inversely proportional to pressure at constant temerature

Mathematically

P1V1=P2V2

P1=Initial pressure=0.8atm

V1=Initial volume=25ml

making V2 the subject

at 0.4atm P2=0.4 atm,

V2=25×0.8/0.4

=50ml

at 2 atm V2=25×0.8/2

=10 ml

1mmHg=0.00131579

2500mmHg=3.28 atm

At 3.28 atm,V2=25×0.8/3.28

=6.097 ml

at 80.0 torr

1 torr=0.00131579

80 torr=0.1052 atm

at 0.1048 atm V2=25×0.8/0.1048

=190.1 ml

Which of the following molecules has one lone pair of electrons?
BigorU [14]
You can automatically rule out CH₄ since it has no lone pairs at all around the central atom. Water has 2. Ammonia is the only Lewis structure that contains one lone pair.

WILL GIVE BRAINLIEST, Which of the following would have the greatest amount of surface area?
Elodia [21]

Answer:

C. 1 cubic foot of loose sand

Explanation:

For many  objects having equal volume , surface area will be maximum

of the object which has spherical shape .

But when a sphere is broken into tiny small spheres , total surface area of all the small spheres will be more than surface area of big sphere .

Hence among the given option , surface area of loose sand will have greatest surface area . Loose sand is equivalent to small spheres .
