The answer is "B) Most species names are written in Swedish because Linnaeus was Swedish." Actually most if not all names in the Modern System of Taxonomic Classification are in Latin.

Three adjacent keys on a piano (F, F-sharp, and G) are struck simultaneously, producing frequencies of 349, 370, and 392 Hz. Wha

PSYCHO15rus [73]

Answer:

21 Hz, 43 Hz and 22 Hz

Explanation:

The computation of the beat frequencies that are generated by this discordant combination is as follows:

As we know that

beat frequencies = |f_1 - f_2|

For the first one

= |349 Hz - 370 Hz|

= 21 Hz

For the second one

= |349 Hz - 392 Hz|

= 43 Hz

And, for the third one

= |370 Hz - 392 Hz|

= 22 Hz

Answer:

work done is 470400 J

Explanation:

given data

long = 3 m

wide = 2 m

deep = 4 m

density = 1000 kg/m³

to find out

Find the amount of work in joules

solution

we know here volume = area × length

area = 0.5 ×base×height

area = 0.5 ×2×4

area = 4 m²

so volume = 4 × 3 = 12 m³

and

weight of water = volume ×density×g

weight = 12 × 1000 × 9.8

weight = 117600 N

work done = weight × height

work done = 117600× 4

work done = 470400 J

The capacitance of an isolated charged sphere is independent of both the ______ on the sphere and the __________, it is dependen

Anestetic [448]

The capacitance of an isolated charged sphere is independent of both the charge on the sphere and the potential difference, it is dependent only on its radius

The capacitance of an isolated sphere is calculated as follows;

let the charge on the sphere = Q

let the potential difference = V

let the radius of the sphere = R

The potential difference is given as;

$V = \frac{kQ}{R}$

where;

k is Coulomb's constant $= 4\pi \epsilon _0$

The capacitance is given as;

$c = \frac{Q}{\Delta V} = \frac{Q}{V_1 - V_2} \\\\at \ infinite \ radius \ R , V_2 = 0\\\\c = \frac{Q}{V_1 } \ \ \ \ (V_1 = V = \frac{kQ}{R} )\\\\c = \frac{Q}{kQ/R} \\\\c = \frac{R}{k}\\\\c = \frac{R}{4\pi \epsilon_0}$

From the equation above, the capacitance (c) is directly proportional to its radius (R) and independent of both the charge (Q) on the sphere and the potential difference (V).

Thus, the capacitance of an isolated charged sphere is independent of both the charge on the sphere and the potential difference, it is dependent only on its radius
